Best Heavy Duty Bench Grinder
1. JET 577102 JBG-8A 8-Inch Bench Grinder
Powerful 8-Inch bench grinder for industrial grade use
As a newbie in the woodworking field, looking for the best bench grinder can be tiresome. An entry-level tool is desirable for its ease of use, but it is limited in terms of features. It will not last long as it keeps breaking down. Even if you are a beginner, it is the experts’ view that you go for something that costs at least $200. The JET 577102 JBG-8A 8-INCH BENCH GRINDER more than just fits this requirement.
Sharpness and general good working condition are the hallmarks of the best bench grinders for woodworking projects. Dull tools not only damage the wood, but also stall your project. Most woodworking projects involve many tools. Sharpening tools is the order of the day for any worker in this industry. While there are numerous grinding tools in the market, this bench grinder is in a league of its own.
Its heavy-duty design sets it apart from other entry-level tools in its class. It features a 1-horsepower, 115-volt motor, which is more powerful than most of the competitors. We are yet to come across an entry-level bench grinder with this kind of capability. With its 3,450 rpm, the JET 577102 JBG-8A 8-INCH BENCH GRINDER is ideal even for heavy grinding applications.
This power is considerable, especially if you have used other bench grinders with half the power. With the JET 577102, you grind your tool comfortably without having to apply too much pressure. It will still run at its incredible speed even if you add some pressure on the wheel.
Also contributing to the top ranking of this bench grinder is its excellent construction, starting with the heavy cast iron base. A compact machine, it weighs in at 58.5 pounds and measures 22.7 x 14.5 x 13.3 inches. Most of the components are actually of cast iron construction. What this means is that vibrations are almost inexistent. To add to this stability and smooth performance, the machine comes with a very effective rubber foot. This is option so you do not have to use it because the machine can be stable without it.
When you look at the eye shields, you note that ease of use goes hand in hand with safety on this tool. These components are large, but they are easy to adjust. For even more safety, the product comes with the following additional features:
- Spark guards
- Cast iron wheel guards
- Dust vents
- Fully enclosed ball bearings
Well, for any bench grinder, you will always find an area of weakness. For the JET 577102, the first disadvantage we noted is the omission of lights. This makes it undesirable for a workshop with poor lighting.
Weight is also a bit of an issue for users that need to move up and down.

How To Choose The Best Bench Grinder
Having gone through the above reviews and many more, you will agree that choosing the best bench grinder is rarely an easy task. As you shop for your first bench grinder, it is important to take your time and follow some guideline. You do not buy a power tool of this caliber hastily or by impulse. Most shoppers who do this end up buying low quality products that do not even fit the requirements of the job.
If the reviews have not given you sufficient guidance, this section outlines important factors that characterize a good bench grinder. Most of them revolve around three features: safety, design and overall quality. We hope you find them helpful as you head to the store.
The motor is easily the most important component of a bench grinder because it revolves the grinding wheel. Consider both the revolutions per minute (rpm) and motor speed. For motors that come with horsepower rating, you will mostly find one-horsepower, ¾-horsepower and 1/2-horsepower motors. A bench grinder with 3,500 RPM or above is perfect.
This is not to say slower bench grinders are not applicable. In fact there are both high speed bench grinders and slow speed bench grinders. So, do not shy away from a 2,000-RPM device. You never know, it could be perfect for your kind of work. Usually, such grinders are most suited for precise grinding since they do not damage the work piece easily. In addition, more people prefer them to faster ones these days.
A powerful bench can generate disturbing vibrations, unless of course some feature to counter this is added. Fortunately, the best bench grinders come with anti-vibration features, some of which we have already covered in the reviews. No matter how powerful the motor is, you will not have to worry about your hands shaking if you buy the best product. A good example of an anti-vibration features is cast iron feet for added grinder stability. Cast iron wheels are also ideal for smooth movement of the equipment.
What we find most relevant and practical to taking care of vibrations is the base. Apart from keeping the grinder stable, it holds the internal parts. You need to search for a tool with high runtime stability, a characteristic that a sturdy base offers. If you are buying a high-speed device, look for this feature as a matter of priority because the vibrations can be pronounced.
The design of the bench grinder must be such that it puts user safety first. Nowhere on the bench grinder are risks as high as near the grinder wheel. This makes the guard a crucial determinant of whether a grinder is good or bad. The grinder spin must stay away from hands. Look for a guard that not only plays this basic role, but also incorporates adjustment settings to cater for different user positions.
Spark shields may or may not feature on the bench grinder, so be alert when buying. Usually, these shields are plastic and are designed to divert sparks away from the user. These shields may be of any shape, but circular and rectangular ones are more common. The most important thing is to pick wide one to maximize protection.
Remember that these should not replace goggles or safety glasses for proper eye protection. Protection is not restricted to the eyes. The best bench grinder should also feature the following.
- Hearing protection
- Hand protection
- Grounded electrical cords
- Anti-restart device
We do not expect any bench grinder to come without a wheel guard, but it is important to be sure it is there. Perhaps you should go for those guards that leave only a small portion of the wheel visible- they offer maximum protection. Make sure the guard is adjustable because you need to be able to change the wheels quickly.
Tool rests play the important role of holding the work piece properly as it is being worked on. You need this feature for added user comfort. This component is your best bet for cutting down on hand and arm fatigue when grinding. Since this is a common feature, you want to look for the best ones. Sturdier and adjustable ones are most preferable.
Some modern bench grinders come with some type of lighting that works on the touch of a button. This feature will come in handy when you are working in dimly lit areas. When a power blackout strikes and you want to continue working, you can count on this feature to illuminate the workstation. Overall, this enticing feature is meant to increase accuracy of work. While this is not a must-have feature, we really recommend it if your garage or workshop is dimly lit.
You already know the relationship between vibrations and weight. However, an extremely heavy tool may be difficult to replace, leave along carry around. Unless you do not mind about mobility and replacements, opt for a relatively lightweight bench grinder. You will note that the best bench grinders do not differ so much in weight, so you should not take so much time choosing in this regard.
Like for any other product, the warranty should guide you when you are buying a bench grinder. The best bench grinders have warranties for both the grinders and the motors. Some will extend to the other built-in parts. Whatever the case, only settle for a warranty of at least one year, so you can have enough time to test performance of the bench grinder.
We may cover all the best bench grinders in the market, but we know that users still want to pose this question, “Where can I get the best bench grinder?” From experience, we are convinced that Dewalt makes some of the best power tools in the market. Their products have a longer lifespan and tend to handle a wide range of jobs.
However, other manufacturers are also doing a good job as attested by this short list of the best bench grinders. The bench grinder market has grown steadily in recent years and the choices are uncountable. Remember to consider what you are going to use the machine for and the features you want. While price is normally indicative of quality, we suggest we take more time to research on pricey products.
Of course, you just need to open the budget to get the most powerful and swiftest tools. Even if you are on a budget, you can still get a product that suits your specific needs. The secret is in shopping around and searching for the best deals.
