TN620 has a higher hardness and greater wear resistance than that of the conventional micro grain cermet. I B IMPROVED TOUGHNESS AND RELIABILITY PV720 improves performance by adopting composite lamination of MEGACOAT NANO and special TiN to combine high adhesion resistance and great visibility of the used cutting edge even in dim light. Wear Resistance Comparison Cutting Conditions Workpiece 4137 Steel Vc - 820sfm D.O.C. = 0.039” f = 0.008ipr: Wet Insert: CNMG432PQ Cutting Time (min) EASY TO VIEW CUTTING EDGE WEAR Improved strength with uniform micro grain hard phase and superior compressive stress with high melting point bonded phase. This combination yields greater fracture resistance. Flank wear condition after machining 48 minutes.
