Grades
KC633M
Coated carbide grade with PVD multilayer coating. KC633M™ is designed for dry milling most types of material, apart from the hardened variety. This grade is characterized by high hardness and wear resistance. It provides outstanding protection for solid carbide tools against cratering and abrasion.
Features and benefits
- Centre cutting for plunging and ramping operations.
- Solid carbide end mills for machining of hard materials greater than 60HRC.
- Also applicable in stainless steel, cast iron, and high-temperature alloys.
