Heavy-Removal Norton Toolroom Grinding Wheels for Metals
Straight
Recessed
Plated Disc
The porous bond leaves more space between abrasive grains so heavy amounts of chips and coolant easily flow through.
32A purple wheels are for medium to heavy material removal. They 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.
