Metal grinding wheels.
 Individual grinding wheels and sets of grinding wheels are made from selected materials and have uniform hardness. Various shapes for a wide range of different applications.
 For grinding and chiseling hard materials such as cast iron, cast iron, malleable cast iron, alloyed and hardened steels. Precision-engineered shanks ensure high concentricity. The shanks have a diameter of 2.35 or 3. General rule for grinding: soft materials = hard abrasive; hard materials = soft abrasive.
