Kennametal Inc.’s KCSM40 indexable milling grade has an cobalt binder that provides thermal fatigue resistance. In addition to the material substrate, Kennametal’s proprietary AlTiN/TiN coating enhances the wear resistance at the cutting edge, the company says.

The milling grade has results milling titanium at speeds up to 270 SFM (85 m/min.) at a lower radial depth of cut. According to the company, the KCSM40 is a grade that aligns with Kennametal’s market segments like aerospace (aero structure and engine components), energy (turbine blades and parts made from duplex stainless steels) and transportation (turbo chargers).
