Kennametal 3763731 HNPJ090543ANSNHD Milling Insert KCPK30

Product Description

The KENNAMETAL 3763731 is a solid carbide hexagon milling insert identified by ISO code HNPJ090543ANSNHD and manufacturer grade KCPK30. It features a CVD-applied multilayer coating of TiN, TiCN, and Al2O3 for wear resistance and thermal stability across a broad range of workpiece materials. The insert has 12 cutting edges, a negative rake angle of 15 degrees, a chamfered and honed cutting edge style, and a 0.1710-inch corner radius. It is held in place by screw clamping and is designed for use in Kennametal Dodeka cutter series toolholders. Thickness measures 0.2142 inches and the inscribed circle is 0.6250 inches.

This insert is suited for milling applications in steel, stainless steel, cast iron, superalloys, and titanium, covering ISO material grades P, M, K, and S. It is a double-sided neutral-hand insert, making it appropriate for both roughing and finishing passes depending on feed and depth settings. The HD chip breaker geometry supports heavy-duty cutting conditions. Maximum depth of cut is 0.2360 inches. Typical users include CNC machinists and tooling specialists in production machining environments handling ferrous and difficult-to-machine alloys.

Compatibility

Designed for use with Kennametal Dodeka cutter series toolholders. Compatible workpiece materials include steel, stainless steel, cast iron, superalloys, and titanium. Insert holding method is screw-type seating.

Installation Notes

Installation is performed by qualified CNC tooling technicians or machinists. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torx or hex key as specified by the toolholder manufacturer to achieve proper screw clamp torque — do not over-tighten or under-tighten the insert screw. Inspect the insert pocket seat for chips or debris before seating a new insert to ensure full contact and accurate positioning.
