Indexable Milling Grade, KCSM40

Published on : Tuesday 30-11--0001

The Kennametal KCSM40 Indexable Milling Grade has an advance cobalt binder that provides exceptional thermal fatigue resistance without sacrificing the toughness customers have experienced with KC725M or X500. In addition to the new material substrate Kennametal’s proprietary AlTiN/TiN coating enhances the wear resistance at the cutting edge. The target cutting speed for KCSM40 in Ti6Al4V was 175 SFM (53 m/min) while achieving a greater than 20 cubic inches per minute (327 cm^3/min) metal removal rate for 60 minutes. Not only has KCSM40 achieved this but has results milling titanium at speeds up to 270 SFM (85 m/min) at a lower radial depth of cut. Recent internal testing with the new HARVI Ultra helical milling platform achieved over 100 minutes of tool life running at 155 SFM (47 m/min) with a .0067 ipt (.12 mm/t) chip load.

The development of KCSM40 was indeed targeting Ti6Al4V but it will be a top performer in other high temperature/heat resistant materials. The KCSM40 is a perfect grade that aligns well 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).
