The Best Wireless Angle Grinder
The best wireless angle grinders are massively loved for their portability and convenience. You can go with these tools anywhere. source of power for these tools is a lithium-ion battery, a technology credited to the efforts of the famous physicist John Goodenough in around 1980, so it would be correct to say that wireless angle grinders are less than four decades old.
These tools can work for as long as you want, provided you have batteries handy. However, an angle grinder naturally uses a lot of power, so power consumption must be minimized through use of small grinders. For this reason, wireless angle grinders may not be equally effective to wired versions.
Design of this tool means there is a permanent magnet. The metal dust in the motor can cause short-circuits, so these machines tend to wear quickly. However, a battered powered grinder has an impressive power-weight ratio. The slow discharge rate of Li-Ion batteries means those of us who forget to plug in our grinders after a long day can still polish a few items the following morning. Check out the following three items.
A) Dewalt DCG412B 20V MAX*
8,000 RPM motor provides high power for cutting and grinding applications
Power tools from Dewalt are renowned for their reliable performance, so its does not take us by surprise that the Dewalt DCG412B does come out top of this list. We have tried out this machine and we can confidently say that it is one of the best in its class. Its versatility on different jobs is amazing.
If we were to single out an excellent feature on this tool, it would be the 7000 RPM motor. This level of power is just what you need to do a wide variety of cutting and grinding jobs.
The battery is easily the most critical aspect of any cordless power tool. Without a good battery, there is no way the user is going to be productive with a cordless angle grinder. The Lithium-Ion battery capacity is good enough for even professionals who want to take full advantage of the powerful motor. It charges fast and retains the charge for many hours so that you can accomplish all those lengthy projects seamlessly.
We mentioned the capability of this tool to tackle a wide range of tasks. Well, several features complement the massive power. First, there is the quick-change wheel, a feature that comes in handy when you need to change the wheel. Believe it or not, you don’t need any tool to change the wheel. The tool also comes with a tool free guard that allows the user to adjust/position the guard easily and quickly.
Even for a machine weighing in at only 5.1 pounds, working for long hours can cause fatigue and blisters. Not with the DEWALT DCG412B. The grip is easy and convenient thanks to the unique 2-finger trigger switch that also incorporates a lock-off button. The 2-position side handle enhances versatility and comfort further. With these features, the user will be in control no matter how a project lasts.
We expect this angle grinder to provide good performance over the years. Highly recommendable.
B) Makita XAG03Z 18V LXT
Automatic Speed Change technology adjusts speed and torque during operation for optimum performance
Like Dewalt, Makita tools are common in jobsites globally. This angle grinder from the renowned manufacturer is so powerful you will think it is connected to the mains. We would recommend this excellent tool to any professional because it has the power, speed and versatility to handle most tasks in the jobsite.
The most striking feature is the brushless motor, which operates at a higher speed and produces more power than many angle grinders in the same range.
Speed variation is a valuable feature if you will be handling a wide variety of materials. The XAG03Z has an edge over many other angle grinders because it features Automatic Speed change Technology, which is exclusive to Makita. This feature offers optimum performance through speed and torque adjustments during operation.
As we indicated earlier, the definition of a cordless power tool is in its battery quality. As you would expect, this wonderful tool comes with a Lithium-Ion battery. The machine is also designed to ensure efficient use of the available power. We are specifically talking about the electronic control of the motor, a design that ensures a significantly longer run time of the tool per charge.
No contractor wishes to buy an angle grinder that does not fit the harsh jobsite conditions; they sometimes just fall the salesperson’s sweet words. Without mincing words, we think that you should consider getting the XAG03Z for your contracts. You will probably not look for a new angle grinder for many years to come. In summary, why we have confidence in the resilience and reliability of this angle grinder:
- Intense power
- Excellent speed
- Compact design
- Variable speed and torque
There you have it! A tool that offers intermediate performance yet it does not cost much. You will probably not get a similar combination of reliability, versatility and power anywhere else for that price.
C) PORTER CABLE PCC761B 20-volt
High-Performance Motor produces 8,500 rpm
Anyone looking for the best angle grinder would pay attention if he/she came across this Porter Cable product. It is high performing, affordable and above all, it comes from a time-tested manufacturer. Since time immemorial, Porter Cable has been producing cheap but very high quality power tools.
Therefore, for a good price, you are getting a tool that will not disappoint- it will give you 8,500 rpm from its monstrous motor. With this power, you can tackle just about any job. This includes even cleaning corroded metal surfaces. This is why we are convinced this angle grinder would suit any do-it-yourself user.
Another win for this tool would be the light weight-only 6.8 pounds. This is the kind of machine that you can use continuously without significant fatigue. It also features the popular 3-position handle that maintains convenience even when you are working in awkward spaces. To add to the ease of use is the spindle lock, which comes into application when you need to change the wheel. Wheel changes have never been easier with this feature.
It is also worthwhile to highlight the fact that the PORTER CABLE PCC761B has a very reliable Lithium-Ion battery. This battery provides excellent power, as evidenced by the inclusion of this tool in the elite cordless platform, popularly known as the 20V Max System. Note that this is a bare tool, so you will get the battery separately.
There is no way we were going to forget the gear housing. We noticed its strong cast metal make, which is assurance for longevity no matter the jobsite conditions. When you use the angle grinder for extended hours, you can be sure the gear housing will dissipate most of the generated heat, thereby enhancing the life of your tool.
If you are constantly working in tight corners and need a powerful tool, this product is exactly what you need. Overall, this is an excellent tool for the given price. If you have Porter Cable batteries already, it is even better.
The Best Wired Angle Grinders
The most attractive thing about a wired angle grinder is its constant connection to a power source. An angle grinder does a lot on the jobsite and a wired tool is the perfect way to maximize this capability. As this grinder can run for many hours, weight and grip are crucial factors. These grinders are built for making deep cuts, so they are generally heavier than wireless versions. Our analysis of the Best Wired Angle Grinders is based on amperage, so we will be looking at 7 Amps, 7 Amps and 6 Amps angle grinders. Read the reviews below for more.
Best Angle Grinders with More Than 7 Amps
Does the amperage of an angle grinder matter a lot? The amperage for angle grinders mainly ranges from 6A to 10A. It is not a secret that grinder speed is largely dependent on power of the motor. If you have been paying more attention to the size than the rating, you have a reason to adjust your considerations a bit. In the next section, we look at several angle grinders that give incredible power of more than 7 amps. As you will notice, these high rated machines are capable of more than their lower rated counterparts are, the obvious choice for power being the 11-amp DEWALT DWE402.
A) DEWALT DWE402 4-1/2-Inch 11-Amp Paddle Switch
If you have not used a wired power tool from Dewalt yet, then you are missing a lot. Everything from this company comes loaded with optimum power and a design to overcome the upheavals of the jobsites.
Talking of jobsite conditions, the best wired angle grinder should be designed to last long. The DEWALT DWE402 promises many years of flawless performance, first if you look at the brushes design. The oversized components ensure this product outlasts many previous models, including the DeWaltD28402. Second, the sizeable spiral bevel gear also adds life to the machine.
We have seen many power tools with incredible weight-power ratios, and we must say this product is among the best angle grinders in this respect. Hold the machine and put it work and you would believe it. Weighing in at only 6.2 pounds, this tool comes with a beastly 11-Amp that is capable of generating 11,000 rpm.
As for cutting quality and capability, the DEWALT DWE402 does not disappoint. Users like the spindle lock button, which the manufacturer uses to maximize cut depth. Contrary to what you might expect in other tools, this feature does not interfere with durability of this angle grinder.
As you enjoy the deep cuts and unmatched power, you will be doing so in the most enjoyable manner. For example, the ergonomics of the grinder are greatly enhanced by the expert combination of plastic and metal construction. The plastic made handle is soft to the touch, yet tough enough to withstand years of use. Further, the Quick-Change wheel release is all you need to remove the wheel-no need for a wrench whatsoever.
Finally but not the least, we also took note of the dust ejection system. Every workplace deserves cleanliness so this tool feature should be popular. This feature ensures long life of the tool by ejecting all debris and dust from the tool.
Its true that the DEWALT DWE402 may not be the most ergonomic angle grinder around, but we believe most users find it comfortable enough. Features such as the expertly designed side handle, lightweight and compact design are rare to find as a set.
B) Kawasaki 841428 4-1/2-Inch
Wheel diameter of 4-1/2-Inch
The Kawasaki 841428 has earned its place in this list because of not only its high quality make, but also its comparatively low cost and incredible amperage. If you are looking for a tool that does not cost that much, but offers all the important packages, you might want to consider this one.
The 3-side handle positions are among the most prominent features on this Kawasaki product. With this type of handling, you can take a sting out of any task effortlessly. Anyone looking for a precise tool will definitely hold this tool in high esteem.
To add to the excellence provided by the handle positions, it is evident that the manufacturers gave construction the best shot. Whether you are talking of the plastic or metallic parts, the tool looks tough and ready for any jobsite.
Even with the sturdy construction, the angle grinder is so good to the hands. The lock-on switch is one thing that will make the user’s life smooth. The handle looks good and it should be a perfect supplement to the friendly weight- 5.7 pounds.
There is something interesting about the 4-1/2-Inch wheel diameter. It is a wheel that accommodates all 4-1/2 in * 5/8 in cutting and grinding wheels. It is so wide that it will accept almost any wheel you bring to it provided it is within the ranges mentioned. You can only find this characteristic in Kawasaki angle grinders.
Having a strong body is one thing, but providing matching power is another. For the Kawasaki 841428, you get both. They made the product using the best materials but did not stop there; they also tested it for durability. This means that even rust cannot bring down this angle grinder. The incredible power you will witness from this machine comes from a reliable 7.5-Amp motor that can give you 3,000 to 11,000-RPM no load speed.
Perhaps you find it a little bit frustrating when the metal shield starts to touch the grinder. We think this is problem is easy to overcome and should not stop you from acquiring this awesome product.
C) WEN 944 7-Amp Angle Grinder
Lightweight design combined with the rubber grip lining for maximum comfort
An angle grinder that is comfortable, lightweight and reliably powerful is something any user will not consider. All these features plus others are packed in this black and orange device.
This lightweight piece of equipment weighs in at only 4.6 pounds. It is also quite small sized with dimensions of 14.5 x 8.5 x 3.8 inches. It is obvious you would find it very easy to take the tool wherever you want.
What about if you are working on a lengthy project? The weight and size may work for you, but the grip can mess things up. We consider the grip very crucial so we checked out how it feels on this tool. The handle is covered in nice rubber that is soft to the hand. Fatigue is non-existent on this kind of rubber so users will be able to work on their projects for hours on end.
When it comes to powering through dirt, rust, etc., be assured of good power from the WEN 4-1/2-Inch 7-Amp Angle Grinder. Its motor generates an impressive 11,000 RPM.
For an angle grinder to be considered truly top class, it needs to have a way of ensuring smooth performance, adequate power notwithstanding. On the WEN 4-1/2-Inch 7-Amp Angle Grinder, you will find a special feature; the lock-on side switch. This switch gives the machine an edge because the user does not have to place thumb on trigger throughout the grinding process.
Are you right or left-handed? You will be at home with this angle grinder. It comes with a reversible handle that can be attached on either right or left side.
Because this angle grinder has an arbor adapter, you can use this feature to use various grinding attachments as long as they have 7/8 or 5/8 inch arbors. This is an excellent enhancement to the versatility of this lightweight tool.
Even though this tool is not that popular and its reviews may not be numerous, you can be sure it has proven itself in the field. It will be a perfect buy if you are looking for good power in a simple tool.
Best 7 Amps Angle Grinders
Considering that the size of the motor of angle grinder will determine the type of work you can do with the tool, it follows then that a 7-amp angle grinder can do a wide range of intensive jobs. Of course, you do not expect tools in this category to have as large discs and high-speed ratings as the group we have just discussed. Interestingly, this is the gold standard of the industry. Most of tools in this class provide just enough power and have manageable weight. We chose and tested the best 7-amp angle grinders as you will find from the following reviews of the specific products.
A) DEWALT DWE4011
7.0-Amp AC/DC, 12,000 rpm motor designed for faster material removal and higher overload protection
This Dewalt tool comes in first place on this list, not by coincidence, but by merit. We liked its all round nature-strong build, seamless performance and good price. As you would expect from anything from Dewalt, this tool comes with some incredible features that have made it popular all over the marketplace.
The powerful motor was one of the surprise packages on this tool. You would not expect a small-sized machine as this one to carry a 7-amp motor and wield massive versatility. The motor can achieve as much as 12,000 rpm, which is ideal for fast material removal. This motor is adequately designed for overload protection too. If you were handling intensive jobs constantly, we would not hesitate to recommend this angle grinder for you.
We also loved the convenience offered by this tool, not only during transportation, but also most importantly on a task. We will single out one notable feature-the One-Touch Guard. The way Dewalt have incorporated this feature reminds us of their engineering prowess when it comes to power tools. If you want to adjust the grinder’s safety guard, all you need is the OTG, as we would like to refer to this innovative feature fondly.
If you are looking to get the best from an angle grinder, you had better consider its durability too. The motor and gearing system is the center of performance, so we are happy to see DEWALT DWE4011 has these areas covered very well. We are talking about the jam-pot gear case whose low profile design enhances longevity and reduces tool size significantly.
We also loved the use of a hex wrench instead of a spanner wrench. This wrench is made of tough material, but even if it were to be damaged, you would easily find a replacement in any toolbox.
One drawback of the compact design is that the machine tends to heat up too fast. However, you can overcome this problem by wearing gloves. Some people will also consider the On/off switch too close to the wheel, which can be a safety hazard.
B) PORTER-CABLE PC60TPAG 7-Amp
7.0-Amp motor powers through jobsite tasks with ease
Not to lag behind, Porter Cable have also designed this equally exciting angle grinder for its clients. Like the Dewalt tool, PORTER-CABLE PC60TPAG is very cost-friendly, falling in the sub $50 region by the time of writing this review.
Talking of reviews, most people are talking positively of this machine in terms of power, convenience, features and price. We may as well conclude that this is one of the best 7-amp angle grinders ever because during our tests, we confirmed most if not all of those reviews.
Starting with power, we are convinced this angle grinder has the muscle to blast through most jobsite tasks. Its 7.0-Amp powerful motor gives about 11,000 RPM so it is suitable for high-speed removal of material.
Talking of convenience, you will realize that this is one of the lightest tools in this power range. It power to weight ratio is incredible. This type of dependable performance is what is needed for the unpredictable jobsite requirements. At a mere 4.1 pounds weight, you can imagine the kind of convenience and versatility this tool gives the user.
We found control features of this angle grinder top-of-the-range, especially the 3-position side handle and the Non-locking paddle. As they enhance versatility, these features are also an assurance of user safety.
The PORTER-CABLE PC60TPAG also comes with a reliable design to match the standards set by the motor. By just looking at the gearbox construction, you will know you this is a jobsite ready tool. Whatever conditions exist in your jobsite, you can be sure this Porter Cable product will survive. Not even a drop will kill it. The comfortable paddle switch will switch off automatically in case you drop this grinder accidentally. That’s a huge feature in safety terms.
While it is rare for a tool made from cast metal and hardened plastic to be damaged before its lifetime, Porter Cable has covered this tool with a three-year limited warranty plus a one-year free service contract. Nevertheless, this is tool is good value for money and we do not expect it to disappoint if used correctly.
C) WEN 944 7-Amp Angle Grinder
Lightweight design combined with the rubber grip lining for maximum comfort
When looking at the versatility of the best angle grinders, you cannot afford to ignore this product by Clifton2Johnson. The removable handle offers something to smile for lefthanders, something they only wish for when using many other models. You can remove it and attach it on the other side for a dream-like experience.
Look at the tool’s weight, build and general ergonomic features and you will understand why it scores highly on user-friendliness. Not many users will complain about a 4.6 pounds weight, especially if it provides beastly power. The same with a 14.5 length, coupled with 8.5 x 3.8 inches width and breadth respectively.
Even if the dimensions and weight do not impress you, we are sure the capability of this nicely designed angle grinder will. The effortless cutting experienced on this tool is largely because of the 7-amp motor, which can generate up to 11,000 RPM. What grinding job will stand against such a sturdy machine running at this speed? Not even rust, pipes and chains. All your heavy-duty grinding jobs are well cared for now.
An incredibly running motor should come with a matching design. The tool’s external body is made of sturdy metal, with a comfortable rubber grip lining for optimum user comfort. Considering the tool is light, holding it for long periods should not be a problem.
Another reason why we think the WEN 944 7-Amp Angle Grinder is a worthy investment for any handyman is the flexibility it exhibits when it comes to using grinding wheels. The tool will accept 7/8- and 5/8-inch arbors so the user can work on many jobs. For this, the tool will be home in many jobsites.
Many will say that the tool comes from a small firm, WEN, and for sure, this may affect uptake to some extent. Despite this, we are confident no one who tries out this tool will complain.
Best 6 Amps Angle Grinders
Are you looking for generally lighter angle grinders with almost as good power as the 7-amp versions? Then you have a pool of choices from leading manufacturers. These machines come with 6-amp motors, just 1amp lower. They will suit you if you are just a hobbyist doing some projects occasionally. If you need a tool for daily use, you probably need to choose from the sturdier ones. These tools will give you incredible power no doubt, and they may still suit industrial use. Below are reviews from reliable and powerful angle grinders from Makita and a couple of other manufacturers. Please read on.
A) Makita GA4530
Compact design at only 4.0 lbs. for reduced operator fatigue
Industrial workers-welders, electricians etc. – need angle grinders for a wide range of applications. From the huge array of tools available, the Makita GA4530 4-1/2-Inch Angle Grinder stands tall as one of the best in the pack. The manufacturer outlines the strengths of the grinder as power, comfort, durability and convenience. After testing this gadget, we were convinced so we put it on top of the list.
Flawless power is guaranteed by the 6.0 AMP motor, which can give as much as 11,000 RPM. This makes it ideal for the mentioned group of users. Moreover, it is lightweight at just 4.0 lbs. You can use the tool for many hours without fatigue.
Are you worried about the tools life? This is one of the most durable tools in its class. Despite its lightness and small size, the Makita GA4530 is hard to beat when it comes to handling tough assignments. Apart from the powerful motor, the tool comes with thicker coil wires and Labyrinth construction for longevity despite the circumstances of use.
We also loved the ergonomic features on the tool starting with the grip. The barrel grip is a mere 2-1/4″ in diameter and offers unmatched comfort. Convenience is enhanced further through the slide switch design that comes with a lock-on. We were not about to forget about the grinder’s side handle. Like in some tools already covered, the Makita GA4530 features a removable handle so it suits both right-handers and lefthanders.
Many would expect to find a variable speed feature in this Makita equipment, but it seems the manufacturer opted to give priority to durability, power and comfort. It seems the lock-on that provides continuous operation is enough for now.
Despite its relatively high price and the noted shortcomings, the Makita GA4530 is still popular with many professionals. Very recommendable.
B) Bosch 1375A 4-1/2-Inch Angle Grinder
Service Minder brush system eliminates guesswork, stops tool when preventative maintenance is required
Every fan of angle grinders has tremendous respect for Bosch products. Their tools are usually affordable, but also of very high quality. Therefore, you can expect the 1375A to be reliable.
At first sight, one may dismiss this tool as just another angle grinder. We expect them to be noisy and awkward on the job. We were amazed at just how quiet this machine is, compared to its peers. It produces manageable noise, but you can still wear earmuffs if your hearing is extra-sensitive. We also noticed that its vibration is almost undetectable.
The smooth operation is unbelievable if you consider the kind of power coming from the machine. This professional tool generates up to 11,000 rpm from its 6.0 amp motor. Vehicle assemblers and building contractors will find this tool very usable because manageable weight and dimensions of 5.2 pounds and 10.5 x 2 x 2 inches respectively crown this power.
Control of an angle grinder depends on many things including shape of tool, control knobs and weight. The Bosch 1375A beats many of its rivals hands down in most these areas. For example, it comes with both Lock-on slide switch and Lock-on/off switch to make extended use possible. The two-sided handle and the sleek body designs add enhance handling.
Many users prefer a versatile tool so this angle grinder is bound to be popular. The weight alone makes the tool suitable for a wide range of applications such as deburring, sharpening, sanding and brushing. However, it is the 5/8-inch-11 spindle that makes it all happen by its compatibility with loads of accessories.
Some consumers have complained about lack of accessories, but we will stick with what has mentioned in the brochures. These accessories are dust collection attachment, cutting guard, Spanner wrench, Auxiliary handle and Flange kit. They also include an abrasive wheel. Our verdict is that the high rating of the 1375A 4-1/2-Inch angle grinder is deserved. Because of the fast-heating motor, you may want to restrict this tool to light jobs.
C) Black & Decker BDEG400
Metal gear case for durability and longer life
Since have associated Black & Decker with high quality yet affordable products all along, we knew this angle grinder would be no exception from the word go. The manufacturer’s innovative solutions are evident in many of the features on this tool.
Its sleek design will take you aback because this is something unexpected of a tool meant for grinding, surface preparation, removing rust, sharpening and cutting. The angle grinder weighs in at a meager 4.8 pounds making it comfortable to the user.
We already listed the many things the tool can do so you can expect it to be loaded with firepower. Despite its small size, the Black & Decker BDEG400 is capable of delivering 10,000 rpm.
Power without control can be dangerous. We must confess that the top-notch control features, most notably the 3 Position side handle, impressed us. It not only adds comfort but also increases the number of applications for this innovative tool. You will rarely come across such a feature unless they start copying.
When you need to different accessories for the many applications easily, the Black & Decker BDEG400 has the solution in the name of a spindle lock. If your matter of concern is how to switch off the machine easily, the rapid shutoff feature comes in handy.
You can also bank on the tool to serve you for many years, as long as you use it responsibly. Its protective metal gear case looks tough and ready to take on any challenge the user presents. So are the plastic components on this machine.
To match the numerous applications, this machine comes with a number of accessories. Of course, there is a spanner wrench to make those wheel changes nice and smooth. Others are a metal grinding wheel and a wheel guard. We know many would have wanted to have a cutting wheel too, but its absence is one of the few drawbacks of this set. Using the tool continuously for a longer time is likely to cause motor problems, so be careful about that.
Generally, this tool is perfect for the hobbyist that only needs moderate applications. You can get a cutting wheel get your project going.
The Best Angle Grinder Kits
As soon as word spreads out that you are looking for the best angle grinder kit, you get all manner of suggestions from family and friends. Knowing that this often-misguiding scenario is common, we have come with a list of the best angle grinder kits to make your search simpler.
Kits are important because they are fruits of the manufacturer’s intensive tests and market research. Most grinder kits have the best possible collection of blades and other attachments. In a kit, the user has the best combination of power, control, reliability and general usability. Do not forget also that a kit will also feature a convenient and reliable case.
A) DEWALT DW840K 7-Inch
Keyless adjustable guard provides tool-free guard adjustments, increasing productivity
First things first, this is an extremely powerful angle grinder. In fact, it is the most powerful in this list. You can only liken the DW840K to the D28499X, although the latter is faster at 9000 rpm. There are many things worth mentioning about this angle grinder, but we feel it scores highest on motor power. It is a 7-inch grinding tool so you expect it to be loaded. Its 13.0 Amp AC/DC motor provides all the required firepower.
A good number of users will go for this machine because of its high power-to-weight ratio. Weighing in at 19 pounds, this tool may seem heavy compared to the tools already reviewed, but when you look back at its motor, you realize that it is actually a gem. User fatigue should be minimal.
If the ratio does not convince you about the convenience of this Dewalt tool, the rear handle design and guard adjustment probably, will. The handle looks so attractive and upon using it, you will be impressed by its control and comfort.
One thing with such a powerful machine is that balance can be a big issue. That is why apart from the comfortable handle, the tool also comes with a 2-Position Side Handle. Fix it at any of the two sides for optimal control of the machine, even in tight spaces.
The manufacturer considered user safety too by including the adjustable guard, which can be set to direct sparks away.
If you still do not like the DEWALT DW840K 7-Inch Angle Grinder, may be it is because of the weight. Otherwise, it is one of the most powerful tools around and very effective, especially in the hands of an expert. If you were doing fabrication projects regularly, we would highly recommend this machine. Remember it comes as a kit comprising of a carrying bag, grinding wheels (5), adjustable guard, wrench and backing flange.
B) Makita 9557PBX1 4-1/2-Inch
Next up is this very worthy ambassador of Makita. If you ever used the likes of Makita 9005B and Makita 9564CV, you have an idea the kind of quality we have at hand here. The 9557PBX1 is similar to 9557PB, the only difference being that it comes with a case.
As we have seen a number of times on this list, this angle grinder also comes with a removable handle. This is an excellent feature because not every user is right handed. Furthermore, the working position can be so awkward that only using the opposite hand will work. To supplement this versatility, this tool comes with a Small diameter barrel grip that measures 2-1/2″”. You can also position its rotatable gear housing after every 90 degrees. We are not sure you would ask for more in this respect.
This kind of design suits jobs that last long. It is also important because the tool weighs in at 11.9 pounds, which would cause fatigue if the design were awkward. Many competitors are not as comfortable so we expect this machine to be an instant hit.
When buying such a powerful machine, safety should be a priority. With this tool, even inexperienced users can grind and cut without fear. The protective guard that keeps debris away ensures the safety of the user. Further, the machine interior is safe from flying debris thanks to the protective zigzag varnish and the labyrinth construction. This is to add to the aluminum casing, which not only conducts heat, but also enhances durability.
Another notable feature is the Lock-on/off component for continuous operation. Add this to the small weight and the 11,000-rpm from the 7.5 amp motor and you have a very reliable machine for demanding jobs. Talking of jobs, this angle grinder impresses in the many number of accessories it accommodates. This package contains a diamond Blade and five grinding wheels.
This tool may not have a variable speed, but it would still make any handyman smile. It is fairly priced and has many nice features.
C) Hitachi G12SR4 6.2-Amp 4-1/2-Inch
Trigger lock-on for comfortable, continuous operation
Finally but not the least, we have this Hitachi machine, one among five options in the 4-1/2-Inch range. It seems Hitachi’s focus is on portability, efficiency and ease of use, having looked at several of their tools.
The Hitachi G12SR4 has a 6.2 amp motor, but you will be surprised it weighs in at only 4 pounds. Yes, 4 pounds for a machine that can finish steel & aluminum, grind welded sections, and remove casting fin. The small weight and compact design make the tool ideal for overhead applications, such as masonry work and painting projects.
This control and convenience of this tool will definitely cause a sensation in the market. For those who are often doing continuous tasks, the hunt for a tool that combines compactness with an array of features seems over. Three standout features in this regard are the trigger lock-on, side handle and spindle lock.
The spindle lock is an irreplaceable feature; it ensures that disc and accessory changes are swift. When working continuously, you need to have total control of the tool. This is especially important when the task is overhead. Both left-handed and right-handed users will find the removable, forward-canted side handle very useful. However, the trigger lock-on contributes the most during continuous operations.
For a powerful tool as this one, user safety is a priority. Of course, the angle grinder comes with a wheel guard as one of the components, but the left-mounted slide switch that caught our eyes too. As the guard protects your eyes from sparks and debris, the conveniently placed switch helps switch off the machine instantly for added safety.
Knowing that you would not want to lose such an awesome machine after several rounds of use, Hitachi added a few features to enhance life. The fact that the set comes with a case is one example. On top of that, the tool boasts of high overload protection and unmatched output power.
Some users are complaining about overheating and lack of a variable speed control. Well, probably these issues should not bother you if you are looking for durability and quality coupled with a good price. Overall, this Hitachi product is recommendable for any contractor or hobbyist because it will do a wide variety of jobs without causing sore muscles.
Are Wireless Angle Grinders the Way of the Future?
Our list has covered some high-class corded and cordless angle grinders in the market presently. We do not which side of your bread is buttered, but we are sure you agree most of these tools rock. One question that will not go is, “Would you replace a wired angle grinder with a wireless one completely?” Time is gone when the motors and batteries were poor quality. Today, we have Makita, Porter Cable and other leading manufacturers designing battery-powered tools that are go-getters. These tools are capable of grinding rigorously and producing a cloud of sparks.
Angle grinders have used batteries for a while now, and it is safe to say that professional grinding is going the cordless way. The ability to work for hours away from the socket is massively appealing. For some time now, battery technology has stalled a bit in terms of improvement and evolution, but this may not affect the shift from corded power.
In summary, cordless angle grinders appear to be the answer for hobbyists or professionals seeking freedom from reliance on grid power. However, we must be cognizant of the fact that a corded tool is still largely superior in terms of run time and amount of power, but tables could turn in the near future.
