The higher the grit or the more coarse the grit, the more powerful that wheel will be. The finer the grit or the less course the grit, the easier the wheel will be for finer sanding or polishing. A higher grit wheel is mostly used on metal to remove rust, where a finer grit wheel can be used to buff or polish without being too abrasive.

Wheel Size

The size of the wheel will help you determine what kind of job the grinder will be able to do. Most commonly, bench grinder wheels will come in 6 inch or 8-inch wheels. This size refers to the size of the actual grinding wheel.

Wheel Type

Power

Some bench grinders will measure the volume of power by horsepower while others use AMPs. The bigger your grinding wheels are, the more power they will need.

Bench grinders will take up much more power and will be able to scale higher capacity jobs, where an angle grinder is best suited for DIY projects or smaller-scale projects.

FAQ

Bench grinders are best used for grinding down metal or to sharpen tools. It is not uncommon to use a bench grinder to help sharpen knives or other sharp-edged tools.
