How to Choose a Good Bench Grinder?


There’s no denying that a more expensive unit would be a more durable bench grinder and last longer, but that doesn’t mean you have to break the bank when it’s time to buy a grinder. Just make sure that the construction doesn’t include many plastic parts and that you provide your unit with regular maintenance.

Wheel Material

Wheel material as a factor to best bench grinders should be assessed to ensure that it is durable and less prone to cracking. Consider the following materials when buying:

Silicon carbide

This is one of the most frequently used bench grinder wheels. However, this type doesn’t work well with high duty or long day works as it tends to overheat very quickly. They are more suitable for sharpening tasks

Aluminum oxide

A more suitable material for hard metals as it doesn’t heat up that much.

Other popular materials include Wire wheels, ceramic aluminum oxide, and buffing wheels.

Wheel Type

Bench grinders usually have two installed wheels, and those wheels are typically composed of different grits and types. For fine grinding tasks, you will usually use a grit size in the range of between 80 to 120. On the other hand, you will have to get medium and coarse wheels in the range of 30 to 60 or (20 – 24) to get the aggressive work done.

Wheen size

Bench grinders come with different wheel sizes depending on their intended use. A smaller wheel is best for sharpening small knives and other tools while a larger wheel is best for tasks like sharpening large blades and metal. You will usually encounter a 6-inch (like delta power tools) and 8-inch wheel in the market.

6-inch wheel

They are less expensive and offer higher RPM (Revolution per Minute) and are mostly used for sharpening knives, sanding metal, and wood. (fine usage)

8-inch wheel

This is the right choice for professionals, like in metalworking shops. It comes with lower RPM which allows more control. However, in some versions, there is a speed control option that enables you to get a higher RPM.

There are also 3-inch wheels that perform well with detailed crafts. If you’re unsure, I recommend going for a 6-inch wheel for regular workers.

Safety Features

Safety features are extremely important when you buy a new bench grinder. Some safety features to look out for are adjustable eye shields, gloves, and snubbing guards. If you wear glasses, make sure the design of the best bench grinder is compatible with your glasses before buying them. You also need to have spark arrestors or an adjustable spark guard to keep the sparks from flying away and setting a fire on.

Important Safety Note: Always keep flammable items away when working with a bench grinder.


How powerful your bench grinder motor is will affect the tasks and materials you can take on. A more powerful bench grinder or heavy-duty motor allows you to do heavy-duty jobs and process larger, harder metals. If you’re going to be working on lighter tasks

Generally speaking, A bench grinder power is measured in either AMPs or horsepower with every 2.1 amp counts to 1/4 horsepower. A 6-inch grinder usually comes with a 1/4 horsepower while an 8-inch grinder is 3/4. There are 1 horsepower grinders out there that are quite powerful and not suitable for regular workers.

While you may need a light touch when using a bench grinder, you also want it to have enough power to do the grinding efficiently without overworking your hands. For instance, if you are only doing the occasional carving job, then a simple 3 amp model might be best for your needs. On the other hand, if you’re doing heavy-duty work with stone then you’ll need to up your amp levels to at least 6 or 7.


What is a variable speed control bench grinder?

Variable Speed Grinders are a type of bench grinder that can change speeds while it’s being used. It allows having superior results with different materials.

Is a variable speed bench grinder good?

Final Thoughts

While the aforementioned products are the Best bench grinders I could find on the market, some of them do a better job combining or focusing on some great features. I’d go for the DEWALT DW758 bench grinders for an affordable yet durable and reliable unit with ample power, speed, and versatility.
