INSERT SELECTION GUIDE P Steel M Stainless steel K Cast iron N Non-ferrous materials S D Super alloys and titanium Hardened steels and irons (greater than 45 HRC) General purpose Heavy machining Normal feed rate normal speed. Meddle rigidity of machine meddle rigidity clamp of tool and workpiece. Normal tool overhang High feed rate reduced speed. Low rigidity of machine low rigidity clamp of tool and workpiece. Long tool overhang Light machining Low feed rate high speed. Good rigidity of machine good rigidity clamp of tool and workpiece.
