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.
