Hardness K

Vitrified Bond - Aluminum Oxide, Hardness Grade K

Mounted points in hardness K are manufactured from a grain mix of pink aluminum oxide and regular aluminum oxide in a vitrified bond. In a medium-hard bond, this abrasive grain combination leads to a good stock removal rate and a long service life. The hardness K is particularly suitable for general use on cast iron parts when used with high peripheral speeds.
