Bench grinders are a versatile workshop tool that can be mounted to a bench (or any flat surface) and used for sharpening, shaping, or polishing your tools. The bench grinder itself is the machine that powers the grind wheels. You can add different wheels for different tasks, such as wire brush wheels for polishing or grinding wheels for sharpening drill bits or smoothing screw threads.

Before you invest in a bench grinder there are a few things you’ll want to consider. First, consider is the size of the wheel, because this will determine the speed and work you are able to do. The 6-inch bench grinders move at a regular speed and are able to accomplish most household tasks. On the other hand, 8-inch bench grinders have a slower speed and are built for professionals who do heavy duty work. Other things to consider are the cooling system, safety guards, lighting attachments, and speed variability.

To help you pick the right tool for the job, here are the top-rated bench grinders on the market today.
