Features and benefits

Versatile solid carbide end mill for steels, stainless steel, and high-temperature alloys with excellent surfaces.

HARVI™ III solid carbide end mills cover a variety of operations, including dynamic milling.

HARVI™ III solid carbide end mills feature unequal flute spacing for chatter-free machining at highest feed rates.

Eccentric relief grind for higher edge stability and higher feed rates.

Centre cutting for plunging and ramping operations.

Grades

KCSM15

Coated carbide grade with thick PVD coating and optimized chemistry
and process for increased wear resistance. Outstanding protection in milling stainless steel to mitigate crater, DOCN (depth-of-cut notching), and flank wear. Excellent performance up to 52 HRC.
