Kennametal 2405375 Milling Insert KC725M Solid Carbide

Product Description

The KENNAMETAL 2405375 is a SEPT-series solid carbide milling insert designed for high-performance metal removal in milling operations. Carrying the manufacturer grade KC725M with a PVD-applied TiAlN coating, this insert delivers wear resistance and thermal stability across demanding cutting conditions. The insert features a square shape with a 90-degree included angle, four usable cutting edges, a positive rake geometry, and chamfered plus honed cutting edge preparation. It measures 0.5512 inches in inscribed circle diameter and 0.1875 inches thick. The chip breaker designation is GB2. Licensed machinists and CNC tool setup technicians are the primary installers of this insert type.

This insert is suited for milling steel, stainless steel, superalloys, and titanium workpiece materials, corresponding to ISO material application codes P, M, and S. It is designed for use in the KSSM cutter series and is compatible with screw-style insert holding systems. The ISO code is SEPT1404AESNGB2 and the ANSI code is SEPT443AESN7GB2. Typical applications include face milling and shoulder milling operations in both production and job-shop environments where consistent edge life and surface finish across difficult alloys are required.

Key Features

• PVD TiAlN coating for thermal stability and wear resistance in steel and superalloy cutting
• Four cutting edges on a single-sided square insert for extended tool economy
• Positive rake with GB2 chip breaker for controlled chip formation
• Chamfered and honed edge preparation for edge strength and reduced chipping risk
• 20-degree relief angle for clearance in milling applications
• Neutral hand configuration for flexible cutter orientation

Compatibility

Designed for use in the KSSM cutter series with screw-style insert clamping. ISO code SEPT1404AESNGB2 and ANSI code SEPT443AESN7GB2 confirm standard insert geometry for interchangeability with compatible toolholders meeting SEPT series specifications.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist or CNC tool crib technician. Power down and lock out the machine spindle before changing inserts. Use the correct torx or hex key to tighten the clamping screw to the toolholder manufacturer's specified procedure — do not overtighten, as this can crack the carbide substrate. Inspect the insert pocket for debris or burrs before seating a new insert.
