Easy-Use Grinding Wheels for Angle Grinders—Use on Metals

The saucer shape lets you hold these wheels at shallower angles than Type 27 wheels, so they’re more comfortable to handle. They are also known as Type 28 wheels and raised-hub wheels.
Wheels are aluminum oxide, which is the most common abrasive used in grinding metal.
Caution: Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.
