PFERD Grinding stone, spherical, KU hardness O

Mounted points in hardness O consist of pink aluminium oxide in a vitrified bond.
These tools are characterized by a very long tool life and good stock removal rate due to the combination of wear resistant grain and a hard bond.
The hardness O is particularly suited for use on edges and for deburring work on steel components.
