Kennametal 2509388 Milling Insert KCPK30 Solid Carbide

Product Description

The KENNAMETAL 2509388 is a solid carbide milling insert with ISO designation EDPT180516PDSRGD and manufacturer grade KCPK30. It features a parallelogram shape with a positive rake angle and a 15-degree relief angle, making it well suited for face and shoulder milling operations where controlled chip flow and edge stability are priorities. The insert carries a CVD-applied multilayer coating of TiN, TiCN, and Al2O3, which provides thermal resistance and wear protection across a broad range of cutting conditions. Two cutting edges are available per insert, and the chamfered and honed edge preparation supports consistent performance in interrupted and continuous cuts alike.

This insert is designed for use in steel, stainless steel, cast iron, superalloys, and titanium workpiece materials, covering material codes P, M, K, and S. It is compatible with the Kennametal Mill 1-18 cutter series and is mounted via screw holding. The GD chip breaker geometry supports positive-rake cutting at moderate to aggressive feed rates. This insert is appropriate for production milling environments where tool life and surface finish consistency across multiple materials are required. Installation is performed by licensed or experienced machinists and tooling specialists.

Key Features

• CVD multilayer coating: TiN, TiCN, and Al2O3 for extended wear resistance and thermal protection
• KCPK30 grade targets steel, stainless steel, cast iron, superalloys, and titanium applications
• Positive rake with 15-degree relief angle reduces cutting forces and supports cleaner chip evacuation
• Chamfered and honed cutting edge preparation improves edge toughness in interrupted cuts
• Two usable cutting edges per insert for improved cost efficiency
• Right-hand insert orientation with GD chip breaker geometry

Compatibility

Designed for use with the Kennametal Mill 1-18 cutter series. Insert style is EDPT, insert size code 1816, ANSI code EP1816S, ISO code EDPT180516PDSRGD. Screw-held single-sided insert seating applies.

Installation Notes

Installation is performed by machinists or tooling technicians using the appropriate Torx or hex key for the screw-clamp system on the Mill 1-18 cutter body. Disconnect and lock out spindle power before indexing or replacing inserts. Confirm insert seating is flush and the clamping screw is fully engaged before resuming operation. Do not exceed the cutter body's rated speed and feed parameters for this insert grade and geometry.
