This is a general purpose grade, which can be used with all materials, it should be run at medium to high cutting speeds. Recommended Feed Rate: 0.05 - 0.15 mm left hand thread right hand thread ISO Material Cutting SpeedVc (m/min) TiAlN Low and Medium Carbon Steels 115 - 280 P High Carbon Steels 130 - 200 Treated Steels 105 - 180 Stainless Steels, Cast Stainless Steels 130 - 190 M Cast Steels 150 - 190 K Cast Iron 80 - 170 Non-Ferrous and Aluminium 180 - 340 N Synthetics, Duroplastics, Thermoplastics 115 - 460 S Nickel Alloys, Titanium Alloys 25 - 90 E - 712 E - 713
