CBN Milling Cutter Insert for Quenching Parts APMT113504 160404 Red Head High Hard Steel
This series of red-tip brazed CBN milling inserts covers APMT113504 and APMT160404 specifications, with high-grade CBN cutting tips vacuum-brazed onto tough tungsten carbide substrates. Specially engineered for quenched hardened steel (HRC45–65), it handles shoulder milling, face milling, semi-finishing and finishing on CNC centers.
The premium CBN material features exceptional hot hardness and abrasive wear resistance at high cutting temperatures, maintaining edge integrity and resisting chipping under heavy machining stress. It delivers excellent surface finish and 5–10 times longer tool life than standard carbide inserts in hard steel operations.
Produced to strict ISO dimensional tolerances, these inserts fit all standard APMT milling cutter heads for quick indexing and direct replacement of conventional carbide blades. Widely used in die making, automotive and bearing manufacturing, they provide premium hard-machining performance with superior cost efficiency.
