Norton General Purpose Toolroom Grinding Wheels for Metals
Use these wheels for precision grinding on surface, cylindrical, and tool and cutter grinders. They are also known as Type 1 wheels and straight wheels.
Truing and cleaning before first use is recommended.
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.
Caution: Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.

Norton Long-Life Toolroom Grinding Wheels for Metals
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.

Centerless Grinding Wheels
Remove material and shape metal cylindrical forms or parts without the need for centers or fixtures. These wheels have tight dimensional tolerances and create a smooth surface. They’re good for grinding numerous materials with just a few machines.
Caution: Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.
