Our indexable carbide milling inserts are core replaceable cutting tools widely matched with CNC face mills, shoulder cutters and high-feed milling tools, serving mold manufacturing, auto parts, aerospace hardware and general metal processing factories worldwide. Made of premium tungsten carbide substrate with controlled cobalt ratio, the inserts reach hardness over HRA 90, featuring outstanding high-temperature resistance, anti-abrasion and anti-chipping performance, with service life 3 to 8 times longer than traditional high-speed steel cutters.
We cover all top searched mainstream specifications to meet full machining demands. APMT1604PDER and APMT1135PDER are universal 90° square shoulder inserts for rough and finish milling of carbon steel, alloy steel and stainless steel, equipped with multi-stage chip breakers to smooth chip evacuation and reduce cutting vibration. RPMW1003MO (R5) and RPMW1204MO (R6) round inserts excel at mold cavity profiling and curved surface processing, delivering smooth workpiece surface without secondary polishing. WNMU080608 double-sided hexagonal inserts stand out in heavy stock removal, supporting six effective cutting edges to lower production cost per piece. MPHT series grooving inserts and SEHT aluminum-specific inserts complete our product lineup for slotting and non-ferrous metal mirror finishing separately.
Adopting advanced PVD and CVD composite coatings including TiAlN and TiCN, our inserts greatly reduce friction and welding during high-speed cutting, effectively resisting thermal oxidation at temperatures above 800°C. Different groove grades are customized for diverse materials: M2 grade for general steel, FM grade for sticky stainless steel, uncoated polished inserts for aluminum to avoid built-up edge. Every insert is ground under micron-level tolerance to guarantee stable dimensional accuracy and consistent surface finish in long-hour unattended machining.
