Kennametal 4034881 Milling Insert KCPK30 Solid Carbide

Product Description

The KENNAMETAL 4034881 is a solid carbide trigon milling insert with the ANSI/ISO designation WOEJ090512SRHD and manufacturer grade KCPK30. It carries a multilayer CVD coating — TiN, TiCN, and Al2O3 — suited for high-heat cutting environments. The insert features a positive rake angle of 15 degrees, a honed T-Land cutting edge style, and an HD chip breaker geometry. With six usable cutting edges on a double-sided configuration, it delivers extended tool life per insert. Thickness measures 0.2150 inches and the inscribed circle diameter is 0.3510 inches. It is designed for screw-held mounting in compatible milling cutter bodies and is right-hand oriented.

This insert is intended for milling operations on steel, stainless steel, cast iron, superalloys, and titanium — covering material grade classifications P, M, K, and S. It is compatible with the KenFeed cutter series and suits both roughing and semi-finishing applications where chip control and thermal resistance are priorities. The KCPK30 grade is well-suited for interrupted cuts and demanding workpiece materials that generate high cutting temperatures. Licensed machinists and CNC setup technicians working in production shops, job shops, and aerospace manufacturing environments are the primary installers and users of this insert.

Key Features

• Solid carbide substrate with CVD multilayer TiN, TiCN, and Al2O3 coating for thermal and wear resistance
• Six cutting edges per insert on a double-sided trigon body, maximizing cost per edge
• HD chip breaker geometry with honed T-Land edge prep for controlled chip formation
• Positive rake angle of 15 degrees reduces cutting forces on challenging workpiece materials
• Right-hand orientation with screw-held mounting for secure seating in the cutter pocket
• Meets ANSI and ISO standards; ANSI/ISO code WOEJ090512SRHD

Compatibility

Designed for use in KenFeed cutter series tooling bodies that accept WOEJ-style inserts. Insert size code 090512 with a right-hand designation. Confirm pocket geometry and screw specification with the cutter body documentation before installation.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before changing inserts. Use the correct torque driver for the clamping screw — refer to the cutter body manufacturer documentation for fastener specifications. Inspect the insert pocket seat and screw thread condition before seating a new insert; a damaged pocket can cause insert movement and premature failure.
