Features and benefits

HP solid carbide deep-hole drills with through coolant for steel, cast iron, stainless steel, high-temperature alloys, and non-ferrous materials.

Application-specific SC drill for drilling holes up to 20 x D up to 4x faster than conventional HSS and gun drills.

Broadest diameter range on the market from .0938–.6299″ (2,383–16mm).

KMH-point geometry is available as a semi-standard, especially for crankshaft applications.

KCPK20™ grade (B27_HPG) is an AlCrN-TiAlN-based coating provides outstanding wear resistance. New ultra-fine-grain carbide ensures process reliability at high feed rates in steel and iron.
