Features of a Good Bench Grinder

Identify Your Needs

Before buying a bench grinder the most important thing you should consider is to know about your needs. That means what type of work you are going to do with the machine is your first consideration. Otherwise, you’ll get a wrong tool which won’t serve your purpose properly.

Go With your Budget

You must have a budget plan for buying the tool, it makes the selection process easier. You can narrow down the brands according to budget and then compare the products within your budget to your requirement, you can easily make the decision.

Choose from Reputed Brand

Though we know that the price of a well known branded product is always a little higher than others. But you’ll also find some less known brands offering competitive products with some great features.

You can choose your tool from these brands. Because it is not only the quality of the product, you also need customer support for any query about the tool. So it is always better to go with a brand.

Work Light

One of the most important things you need to look for while purchasing a new grinder is whether it comes with a work light or not. You also need to check the type of the work light. Some work lights are flexible & attached over the unit, some may directly build in it and can be located over the wheels instead. Some have more than one light in it which makes it easy to operate the grinder.

So choose the one with which you can complete your job comfortably.


You may select the package that offers you different wheel options. Though no one comes with all types of them, you can go with the one which has at least a set of fine- medium or coarse wheels with the kit.

You also need to check the material of the wheels. For grinding steel, wheels made of vitrified aluminum oxide will work great. Whereas, silicon carbide is good for cast iron or other nonferrous materials.
