Kennametal 2273388 Milling Insert EDPT180548PDERGD KC725M

Product Description

The KENNAMETAL 2273388 is a solid carbide milling insert in the EDPT series, designed for indexable face and shoulder milling operations. Carrying the ISO designation EDPT180548PDERGD and manufactured to the KC725M grade, this insert features a TiAlN PVD coating applied over a solid carbide substrate, delivering heat resistance and wear performance suited to interrupted and continuous cuts. The insert has a parallelogram shape with a 70-degree included angle, a positive rake geometry, a honed cutting edge, and the GD chip breaker. Thickness is 0.217 inches and the inscribed circle measures 0.426 inches. Two cutting edges are available per insert, and the holding method is screw-clamped.

This insert is intended for milling steel, stainless steel, superalloys, and titanium, covering material grade codes P, M, and S. The positive rake and GD chip breaker combination supports controlled chip evacuation when machining these demanding materials in production environments. It is compatible with the Mill 1-18 cutter series and is suited for both CNC machining centers and manual milling equipment where EDPT-style toolholders are used. Installation is right-hand orientation. The ANSI code is EP1848E and the ISO code matches the insert designation EDPT180548PDERGD. This insert is sold individually with a minimum order quantity of 5 pieces.

Key Features

• KC725M grade solid carbide substrate with TiAlN PVD multilayer coating for extended tool life in steel and superalloy applications
• GD chip breaker with positive rake geometry for controlled chip formation and reduced cutting forces
• Honed cutting edge style reduces micro-chipping at the cutting edge during entry and exit
• Two usable cutting edges per insert maximizes value per piece
• 15-degree relief angle supports clearance in close-tolerance milling passes
• Screw-lock holding method provides secure, repeatable seating in the cutter pocket
• Conforms to both ANSI and ISO standards, enabling direct replacement in standard EDPT tooling systems

Compatibility

Compatible with the Kennametal Mill 1-18 cutter series. Insert style is EDPT, insert size code is 1848, and the ANSI code is EP1848E. Right-hand orientation only. Verify cutter pocket geometry and screw size before installation.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. The machine spindle must be locked out and the cutter body secured before seating or replacing inserts. Use the correct torque driver for the clamping screw to avoid pocket damage or insert fracture — refer to the cutter body documentation for the specified torque value. Inspect the cutter pocket seating surface for chips or debris before installation, as contamination will affect insert position and edge runout.
