Individual grinding wheels and sets of grinding wheels are made from selected materials and have uniform hardness. Various shapes for a wide range of applications.
 
For grinding and chiseling hard materials such as cast iron, cast iron, malleable cast iron, alloyed and hardened steels. Dimensionally precise 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.
