Grades
KC643M
Coated fine-grain grade with PVD multilayer (AlTiN). KC643M™ is a very thin and hard PVD coating particularly suited for cutting steel, cast iron, stainless steel (wet), and titanium (wet). This grade can be used for materials with hardness up to 52 HRC.
Features and benefits
- Center cutting for plunging and ramping operations
- Solid carbide end mill with flat shallow profile, offering a good compromise between surface finish and power consumption
