Grades

KCK10A

Composition: Multilayered PVD AlTiN-based coated submicron grain carbide with superior surface finish.
Application: First choice for cast iron. This grade utilizes a newly developed coating combined with a state-of-the-art surface condition to offer extraordinary wear resistance in abrasive materials at elevated cutting conditions with improved performance consistency.

Features and benefits

Proven performance with our HPR drills geometry, featuring our heat and wear resistant KCK10A grade.
High productivity with speed four times faster than conventional drills.
Longer tool life in steel and iron compared to competitors.
Bottom-line savings from increased metal removal rate.
