PFERD Grinding stone, conical, KE hardness R

Mounted points in hardness R are manufactured from grey silicon carbide in a vitrified bond.
The combination of very hard abrasive grain and high bond content means that extremely long tool life is achieved when grinding.
The hardness R is particularly suitable for use on edges and for grinding out metal contamination on grey and nodular cast iron at high cutting speeds.
- The maximum permitted rotational speed refers to the unsupported shank length of 10 mm
