For interrupted cutting and cutting through scale. .013" Flank Good balance of cutting edge strength and low cutting resistance. f (IPR) CNMG432RP RM Recommendation for rough cutting of stainless steel Stainless SteelDouble sided chipbreaker. Corner.012"3° Excellent fracture resistance during interrupted cutting due to the optimum cutting edge land angle and honing geometry. .012" Flank 6° f (IPR) CNMG432RM RK Recommendation for rough cutting of cast iron Cast Iron Flank Seating surface and wide land 3 or more times that of conventional 15° .014" products provides high cutting stability for interrupted machining and scale removal. f (IPR) CNMG432RK RS Recommendation for rough cutting of Difficult-to-Cut Materialsdifficult-to-cut materialsSeating surface and land width 3 or more times that of conventional25°Flank.008" products and provides high cutting stability for interrupted 10° machining and scale removal. f (IPR) CNMG432RS Recommendation for rough cutting of Carbon Steel·Alloy Steel Corner carbon steel, alloy steel and stainless steel Double sided chipbreaker. For interrupted cut and removing scale. Flank A combination of wide land and large chip pocket allows high feeds. f (IPR) CNMG432GH Recommendation for rough cutting of Difficult-to-Cut Materials Corner difficult-to-cut materials Double sided chipbreaker. Excellent balance of edge sharpness and strength. Flank Edge geometry with high face wear resistance. f (IPR) CNMG432GJ Recommendation for heavy cutting of mild steel and Mild Steel Corner stainless steel Single sided chipbreaker. Appropriate for the lower end of the heavy cutting region. Flank Low cutting resistance due to positive land and curved edge. Teardrop dots improve chip control without increasing cutting resistance. f (IPR) CNMM644HZ HL Recommendation for mild steel and stainless steel Mild Steel Low resistance due to narrow flat land. Achieves high chip breaking ability. 15° .013" f (IPR) CNMM644HL HM Assist breaker for mild steel and stainless steel Mild SteelFlat land provides outstanding balance between cutting edge strength and sharpness. 16° .013" f (IPR) CNMM644HM A054
