RPMW1204MOSN M6310 R6 Round Milling Insert, High Hardness Carbide CNC Tip for HRC45-62 Hardened Steel Machining
This RPMW1204MOSN round carbide milling insert adopts professional M6310 grade, specially developed for high-hardness and difficult-to-machine metal materials. Featuring R6 cutting radius, it delivers stable performance for milling hardened steel workpieces within HRC45 to HRC62 on CNC machining centers.
The M6310 grade uses ultra-fine grain carbide substrate matched with premium PVD hard coating, balancing excellent red hardness and edge toughness. It effectively resists edge chipping and abrasive wear under high-speed cutting, keeping sharp edges for long continuous machining of hardened workpieces.
Compatible with standard RPMW type round milling cutter holders, each insert passes strict dimensional inspection for consistent machining accuracy. Widely used in die steel and mold manufacturing, it delivers reliable surface finish and cost efficiency for mass production of high-hardness parts.
