For use in semi-finishing and finishing applications. Due to the precise -421 control of the cutting edge, this geometry provides excellent results when machining High Temperature Alloys. -422 This positive geometry with a 11º chip angle and an “E” edge preparation for roughing and semi finishing applications. Primarily for -422 machining of Stainless Steels and High Temperature Alloys. Also can be used in Steel, Steel Alloys and Cast Irons with very good results. -423 A strong positive geometry first with a smaller primary angle and a small controlled hone to reduce cutting pressures, followed by a higher -423 secondary angle to allow free cutting of the chip without rubbing on the insert rake face. Chip flow compresses the chip for easy evacuation. For roughing and semi-finishing of Nickel Based Alloys, Cobalt Alloys, Stainless Steels, Titanium Alloys and High Temperature Alloys. -441 This geometry is a peripheral ground insert with a sharp cutting edge for use on Aluminium Alloys, Copper and Brass. The –441 geometry -441 provides freer cutting operations and reduces the “suction effect” associated with higher helical geometries. www.kennametal.com A21
