Kennametal launches new KYHK15B ceramic grade

Higher wear resistance and longer tool life in hard turning applications up to 58 HRC with Kennametal’s KYHK15B grade.

The new ceramic grade delivers highest productivity when machining hardened steels, high-temperature alloys, and cast irons.

Kennametal has introduced its latest ceramic turning grade, KYHK15B, designed to deliver increased productivity and lower cost per edge in hard turning operations.

The new grade provides greater depth of cut capabilities than PcBN inserts when machining hardened steel, high-temperature alloys, and cast iron, as well as maximum tool life and wear resistance for the most demanding turning applications.

“KYHK15B provides excellent edge stability, high chipping resistance, and a PVD gold coating makes wear progression identification very easy. From smooth and varying depths of cut to heavy depths of cut, KYHK15B can be an economic alternative to PcBN inserts,” said Robert Keilmann, product manager, Kennametal.

KYHK15B builds on an existing line of high performance ceramic turning grades, providing manufacturers a productive solution for hard turning applications even in varying or heavy depths of cut.
