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.

Norton 38A Abrasive—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.
