APMT1135/1604PDER-PM/PR GA4225 GA4230 Carbide Milling Inserts

This APMT series carbide milling insert includes APMT1135PDER-PM and APMT1604PDER-PM/PR specifications, available in GA4225 and GA4230 grades. With PM and PR optimized chipbreaker structures, it is developed for face milling and shoulder milling of steel, stainless steel and alloy steel on CNC machining centers.

The fine-grain carbide substrate paired with high-performance coating balances excellent wear resistance and edge toughness. The PM/PR groove design lowers cutting force, optimizes chip evacuation and reduces built-up edge, ensuring stable cutting in roughing and semi-finishing of various metal workpieces.

Compatible with standard indexable milling cutter holders, each insert undergoes strict dimensional inspection to guarantee consistent machining accuracy. Widely used in mold, automotive and general machinery industries, it delivers reliable performance and cost efficiency for mass metalworking production.
