Made by Norton in the USA, to our exacting specifications, these white aluminum oxide grinding wheels are the most cost effective solution for sharpening high speed steel turning tools. The wheels are a "J" hardness, and friable, so the worn cutting particles are released from the wheel, exposing fresh ones. This way less heat is generated during grinding. This action is very useful when grinding harder metals like high speed steels used in turning tools. White aluminum oxide wheels will make your grinder more "user friendly" and will put a sharper edge on your turning tools.
The 7" and 8" wheels have bushings to fit shafts from 5/8" up to 1-1/4" diameter.
