Grades
KCM15
Composition: Nanostructured PVD TiAlN coated fine-grain carbide with a golden TiN top layer for better wear identification and superior surface finish.
Application: A state-of-the-art surface condition enhances low adhesion potential to stainless steel materials and offers superior chip evacuation even in low-pressure coolant applications. Applicable for stainless steel and high-temperature resistant materials.
Features and benefits
- HP Beyond drills with through coolant for stainless steel.
- Material-specific SC drill offering high performance and long tool life in regular steel and titanium materials.
- By combining unique Kennametal technologies, such as the HP point, flute geometry, and a new Beyond grade technology into one tool, the B21_HP is the ultimate high-volume production tool.
- HP point enables high feed rates by progressive rake angle.
- KCM15™ Beyond grade is a nanolayer, TiAlN-based coating with high wear resistance and low adhesion to stainless steel materials.
- The highly polished surface ensures superior chip evacuation even when low-pressure coolant is applied.
