Super Hard Milling Insert APMT1604/RPMT1204 KK800 High Performance OEM Tialn Coated 45HRC Round Turning Center
This series of super-hard CNC milling inserts includes APMT1604 (R0.8 shoulder milling) and RPMT1204 (R6 round nose profiling) models, built with premium KK800 super-hard carbide grade. As a high-performance domestic replacement for imported brands, it excels at heavy roughing and semi-finishing on quenched die steel, mold steel and high-hardness alloys.
The specialized KK800 grade combines ultra-fine grain carbide substrate with advanced wear-resistant coating, delivering exceptional hot hardness and chipping resistance under high cutting stress. It maintains stable cutting performance and extended tool life when processing hardened materials under heavy intermittent loads.
Manufactured to strict ISO dimensional tolerances, these inserts are fully compatible with mainstream APMT and RPMT milling cutter heads for fast indexing and accurate clamping. Widely used in die making, mold manufacturing and precision tooling, they deliver imported-level quality at significantly lower tooling costs.
