Kennametal 2509387 Milling Insert EDPT180516PDSRGD KC725M

Product Description

The KENNAMETAL 2509387 is a solid carbide milling insert manufactured to the ISO designation EDPT180516PDSRGD and offered in the KC725M grade. This single-sided, right-hand parallelogram insert features a TiAlN coating applied via PVD process, providing thermal resistance and wear performance in demanding milling operations. The insert measures 0.858 inches in length, 0.428 inches wide, and 0.217 inches thick, with a 1/16-inch corner radius. It carries a positive rake geometry with chamfered and honed cutting edges and delivers two cutting edges per insert. Screw-type insert holding secures the insert within compatible toolholders.

This insert is intended for face and shoulder milling applications targeting steel, stainless steel, superalloys, and titanium workpiece materials, corresponding to ISO material groups P, M, and S. The positive rake and GD chip breaker geometry make it well suited for finishing and semi-finishing passes where controlled chip evacuation and surface finish quality are priorities. It is installed by machinists and toolroom technicians operating CNC milling centers in both job shop and production environments. The insert is compatible with the Mill 1-18 cutter series and is identified by ANSI code EP1816S.

Key Features

• KC725M grade solid carbide substrate with TiAlN PVD coating for extended tool life in steel and superalloy milling
• Positive rake geometry with chamfered and honed cutting edges for reduced cutting forces
• GD chip breaker designed for controlled chip evacuation in finishing and semi-finishing operations
• 15-degree relief angle reduces flank wear in interrupted and continuous cut conditions
• Right-hand, single-sided insert with two usable cutting edges per insert
• Screw-type clamping for secure, repeatable seating in compatible toolholders

Compatibility

Designed for use in the Kennametal Mill 1-18 cutter series. ISO designation EDPT180516PDSRGD and ANSI code EP1816S confirm dimensional and geometric fitment. Suited for machining steel, stainless steel, superalloys, and titanium in ISO material groups P, M, and S.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before seating or removing inserts. Use the appropriate Torx or hex key driver as specified by the toolholder manufacturer for the clamping screw. Inspect the insert pocket for debris or damage before seating a new insert to ensure proper contact and prevent premature edge failure.
