Kennametal 2451579 Milling Insert KC725M Solid Carbide

Product Description

The KENNAMETAL 2451579 is a solid carbide milling insert designed for indexable milling operations in demanding metalworking applications. Manufactured to the ISO designation EDCT180512PDERGD and ANSI code EC1812E, this insert features a parallelogram shape (EDCT series) with a positive rake geometry and a GD chip breaker. The TiAlN PVD coating provides thermal resistance and wear protection at the cutting edge. The honed cutting edge style reduces microchipping during interrupted cuts. With two cutting edges per insert and a right-hand orientation, the 2451579 is intended for single-sided use and is held in place by a screw-clamp method in compatible toolholders.

This insert is suited for milling steel, stainless steel, superalloys, and titanium under the KC725M manufacturer grade, which corresponds to material grades C5, C6, and C7. The EDCT series and insert size code 1812 make it compatible with Mill 1-18 cutter series toolholders. It is typically installed by CNC machinists and toolroom technicians performing face milling, shoulder milling, or contour milling operations on medium to high-strength workpiece materials where controlled chip formation and edge stability are critical.

Key Features

• TiAlN PVD coating for elevated-temperature wear resistance in steel and superalloy cutting
• GD chip breaker geometry promotes positive chip control across a range of feed rates
• Positive rake angle reduces cutting forces and heat generation at the tool-workpiece interface
• Honed cutting edge minimizes microchipping and extends edge life in interrupted cuts
• Right-hand, single-sided parallelogram insert with screw-clamp retention
• Meets ANSI and ISO standards; ISO code EDCT180512PDERGD, ANSI code EC1812E

Compatibility

Designed for use with Mill 1-18 cutter series toolholders. Insert size code 1812 with screw-clamp retention. Primary workpiece materials are steel (P), stainless steel (M), superalloys, and titanium (S). Verify toolholder pocket geometry and insert seating torque specifications against the Mill 1-18 system documentation before installation.

Installation Notes

This insert is installed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before changing inserts. Use the correct Torx or hex key driver recommended for the screw-clamp retention system and do not over-torque the clamping screw. Inspect the toolholder pocket for debris or damage before seating the new insert.
