A more durable abrasive allows these wheels to remove more material and last longer than Norton General Purpose Grinding Wheels. They are also known as Type 1 wheels and straight wheels.

Truing and cleaning before first use is recommended.

32AA purple wheels are for medium to heavy material removal. They are a blend of aluminum oxide and ceramic aluminum oxide, which lasts up to twice as long as Norton 32A General Purpose Grinding Wheels.

5SG blue wheels are for heavy material removal. They are ceramic aluminum oxide, which lasts up to five times as long as Norton 32A General Purpose Grinding Wheels.

Caution: Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.

The special shapes of these wheels provide more clearance than typical straight wheels.

38A white wheels are for light material removal. They stay cool during use, so they're a good choice for heat-sensitive applications. They are aluminum oxide, which is the most common abrasive used in grinding metal.

32A purple wheels are for medium to heavy material removal. They are aluminum oxide.

32AA purple wheels are for medium to heavy material removal. They are a blend of aluminum oxide and ceramic aluminum oxide, which lasts up to twice as long as 32A wheels.

5SG blue wheels are for heavy material removal. They are ceramic aluminum oxide, which lasts up to five times as long as 32A wheels.

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.

5SG blue wheels are for heavy material removal. They are ceramic aluminum oxide, which lasts up to five times as long as 32A wheels.

Unlike aluminum oxide wheels, these silicon carbide wheels won't clog when grinding soft metals.
