Composition: Multilayered PVD TiN-TiAlN coated fine-grain carbide with superior surface finish.
Application: First choice for alloyed and high-alloyed steel and cast iron. A state-of-the-art surface condition enables superior chip evacuation and offers highest level of wear resistance at enhanced material removal rates.

Features and benefits

HP Beyond step drills with through coolant for steel and iron.
Application-specific SC drill that offers a one-pass solution in steels and irons in traditional tap sizes to reduce cycle time and increase productivity.
Drilling and chamfering in one shot.
HP point enables high feed rates by progressive rake angle.
KCPK15™ Beyond grade is a multilayer, TiAlN-based coating with high hot hardness that enables high cutting speeds, even in MQL applications.
The highly polished surface ensures superior chip evacuation even when low-pressure coolant is applied.
