Why a Bench Grinder Is the Essential Work Bench Tool

Bench grinders do a great job of sharpening tools, especially when you purchase a single-speed model. If it is rated for 3,000 RPM or more, then you can consistently create sharp tools for your next project. This makes it a lot easier to maintain your equipment so that your woodworking creativity can always be explored.

Yet the bench grinder becomes an essential workbench tool when you choose a model that comes with variable speeds. Once you can have lower RPMs and the discs are interchangeable, then you can use your bench grinder for buffing, polishing, and cleaning.

You also have size options available to you that can facilitate grinding, cleaning, and the other aspects of this tool that you may wish to use. Most bench grinders are either 6-inch or 8-inch models. The 8-inch grinder is generally the best option from which to choose as it provides a 0.25-inch larger wheel that is accessible to the user.

There are 10-inch models available as well, which pushes the wheel size to 1.25 inches. Some manufacturers have commercial or industrial models that go beyond 10 inches, but for the average woodworker, the best value comes with the 8-inch model.

How to Properly Use Your New Bench Grinder

It is important to store your bench grinder in a careful manner. Most of the wheels that you’ll be using with this tool are glass-bonded products, so they are strong, but can still be quite brittle. Any unexpected impact could damage the wheel or the bench grinder – and that type of damage is usually not covered by a manufacturer’s warranty.

You’ll also want to check the machine speed against the safe operating speeds that are listed on your preferred grinding wheels. Over-spinning a wheel above its ratings can cause it to dislodge from the bench grinder. This could injure you or cause a lot of damage on your workbench.

Most bench grinders will require you to mount them before use. The only exception would be portable bench grinders that are balanced in a specific way. The last thing you want to have happen is your bench grinder falling over with a sharp tool in your hands, so make sure you’ve given this tool a solid base before using it.

Above all else, you’ll also want to control dust and protect yourself from particulates when using the best bench grinders for woodworking. Use your personal protective equipment and consider adding a dust collection bin or bag if your preferred model does not collect dust on its own. Breathing in glass, grit, and metal shavings is not a pleasant experience.

We’ve determined that the award for best bench grinder for woodworking should go to the Dewalt model for its heavy duty grinding and stable operation.

How to Maintain Your New Bench Grinder

Owning a bench grinder is just one step of the process. For proper woodworking, you’ll also need to know how to maintain your bench grinder. Otherwise you’ll be only receiving a partial benefit from this tool and you could be putting your project or your health at risk.

Most wheels are made from aluminum oxide or silicon carbine. Ferrous metals benefit from the first type of wheel, while all other metals benefit from the latter wheel type.

To maintain these wheels, you’ll want to dress them regularly so that you can remove any clogged grains that may be on the wheel. You have two options available to you: diamond dressers or star-wheel dressers.

We recommend this diamond dresser for general needs

We also recommend this emery star-wheel dresser.

For general cleaning purposes, the star-wheel dressers will give you consistently clean grains. If you have cleaned the wheel several times already, then the diamond dresser is a better option because it will help to restore the sharpness of the wheel to some extent. Just run the dresser over the wheel as instructed by the manufacturer.

You’ll also want to inspect your bench grinder to ensure there are no cracks in the wheel before and after use. The most common reason for wheel cracking is an over-tightening of it.

What will it cost me to buy the Best Bench Grinders?

Compared to the cost of constantly replacing dull tools or having a professional sharpener address them for you, a bench grinder is reasonably affordable. There are several models that are available right now for less than $100. Most of the cheaper bench grinders are 6-inch models, however, so they may not be suitable to the needs of every woodworker.

Most bench grinders fall between $100-$200. At this price, you can find an 8-inch bench grinder with features like an attached light.

Industrial-grade bench grinders can be priced all the way up to $1,000.

Over time, you will also need to replace the various wheels that are being used with your bench grinder as well. Prices go up based on the fineness of the grit that is required. 36-Grit wheels can be found for $10, while 6,000-grit wheels may cost upwards of $100 each. Most woodworkers can find replacement wheels between these two pricing extremes.
