Kennametal 2405377 Milling Insert KCPK30 Solid Carbide

Product Description

The KENNAMETAL 2405377 is a solid carbide milling insert in the SEPT series, designed for high-performance face and shoulder milling applications. It carries a CVD-applied tri-layer coating of TiN, TiCN, and Al2O3, which builds wear resistance and thermal stability during interrupted and continuous cuts. The insert is square in shape with a neutral hand orientation, a positive rake geometry, and chamfered plus honed cutting edges for controlled engagement. With four usable cutting edges per insert and an ISO designation of SEPT1404AESNGB2, this single-sided insert suits demanding production milling where tool life and surface finish consistency are priorities.

This insert is suited for milling steel, stainless steel, cast iron, superalloys, and titanium, covering material grades C1, C5, and C6 with ISO application codes P, M, K, and S. It is compatible with the KSSM cutter series and is typically installed in machining centers and CNC milling machines in both job-shop and production environments. Machinists and tooling technicians working in aerospace, general metalworking, and heavy manufacturing will find this insert appropriate for a wide range of roughing and semi-finishing passes.

Key Features

• CVD tri-layer coating: TiN, TiCN, and Al2O3 for extended wear life in steel and cast iron
• Four cutting edges per insert for reduced per-edge tooling cost
• Positive rake with chamfered and honed cutting edge style for controlled chip formation
• GB2 chip breaker geometry optimized for the SEPT series
• Neutral hand orientation allows flexible cutter body seating
• Meets ANSI and ISO standards; ANSI code SEPT443AESN7GB2

Compatibility

Compatible with the KSSM cutter series. This insert is identified by ISO code SEPT1404AESNGB2 and ANSI code SEPT443AESN7GB2, and is designed as a direct-fit replacement for applications specifying SEPT-series inserts in KCPK30 grade.

Installation Notes

Installation is performed by qualified machinists or tooling technicians using the screw-holding method standard to SEPT-series cutter bodies. Power down and lock out the machine spindle before seating or removing inserts. Verify pocket cleanliness and screw torque per cutter body manufacturer specifications before resuming cuts. Do not exceed the cutter body's rated speed or depth-of-cut parameters for this insert geometry.
