Uses and application
Grades
KCMS20
Composition: Monolayer PVD AlTiN coated ultra-fine-grain carbide with superior surface finish.
Application: First choice for deep-hole drilling of stainless steel and high-temperature resistant materials. Due to the coating's enhanced high-temperature properties, this grade can also be applied to MQL applications in steel.
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 40 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.
- KCMS20 grade (B27_SGL) is a monolayer PVD AlTiN coated ultrafine grain carbide with superior surface finish. First choice for deep hole drilling of stainless steel and high-temperature resistant materials. Due to the coatings enhanced high temperature properties this grade can also be applied for MQL applications in steel.
