Kennametal 2390264 Milling Insert SEKT1404AESNGP2 KCPK30

Product Description

The KENNAMETAL 2390264 is a solid carbide square milling insert in the SEKT series, grade KCPK30, designed for high-productivity face and shoulder milling operations. The insert features a CVD-applied multilayer coating of TiN, TiCN, and Al2O3, which provides thermal resistance and wear life across a broad range of workpiece materials. With four cutting edges, a positive rake geometry, and a chamfered and honed cutting edge style, this insert is built for stable, controlled cuts in demanding production environments. It is installed via screw-holding method and is compatible with the KSSM cutter series. Machinists and tool crib technicians in job shops and production facilities specify this insert for its versatility across material grades P, M, K, and S.

This insert is suited for milling steel, stainless steel, cast iron, superalloys, and titanium in both roughing and finishing applications. The GP2 chip breaker geometry manages chip flow effectively across these material groups. Its neutral hand orientation makes it adaptable for standard SEKT-style toolholders. The SEKT1404AESNGP2 ISO code and SEKT443AESN7GP2 ANSI code confirm fitment in tooling systems referencing either standard. This insert is appropriate for CNC machining centers in both light and moderate cutting conditions where consistent edge performance is required.

Key Features

• CVD multilayer coating: TiN, TiCN, and Al2O3 for thermal and abrasion resistance
• Four cutting edges per insert for extended tool life and lower cost per edge
• Positive rake with chamfered and honed cutting edge style for controlled entry and reduced chipping
• GP2 chip breaker optimized for steel, stainless steel, cast iron, superalloys, and titanium
• Screw-holding method for secure seating in KSSM cutter bodies
• Meets ANSI and ISO insert standards; dual-coded SEKT443AESN7GP2 and SEKT1404AESNGP2

Compatibility

Compatible with the KENNAMETAL KSSM cutter series. Conforms to ISO code SEKT1404AESNGP2 and ANSI code SEKT443AESN7GP2. Suitable for toolholders accepting SEKT-style square inserts with screw-holding retention.

Installation Notes

Installation is performed by machinists or tooling technicians on CNC milling equipment. Power down and lock out the spindle before indexing or replacing inserts. Use the correct Torx or hex key for the clamping screw and ensure the insert seat is clean and free of chips before seating the new edge. Follow the cutter body manufacturer's recommended clamping torque procedure as specified in the toolholder documentation.
