Kennametal 3855210 Milling Insert EDPT140404PDSRGE KC725M

Product Description

The KENNAMETAL 3855210 is a solid carbide milling insert manufactured to ANSI code EP1404SGE and ISO code EDPT140404PDSRGE. It carries the KC725M manufacturer grade and features a TiAlN coating applied via PVD process, optimizing wear resistance and thermal stability during interrupted and continuous milling operations. The insert is parallelogram-shaped (EDPT series), right-hand cut, single-sided, with 2 cutting edges and a positive rake geometry at 20 degrees. The GE chip breaker and chamfered, honed cutting edge style are suited for stable chip control. Thickness measures 0.1772 inches and inscribed circle measures 0.3230 inches. Weight is 0.05 pounds per unit. Licensed machinists and CNC setup technicians are the primary installers.

This insert is designed for milling applications in steel, stainless steel, superalloys, and titanium — corresponding to material grade codes P, M, and S. The EDPT series and 1404 insert size code place it in face milling and shoulder milling contexts where positive rake and a 15-degree relief angle reduce cutting forces on heat-sensitive or work-hardening materials. It is compatible with the Mill 1-14 cutter series. The screw holding method provides secure seating in the cutter body during high-feed passes. Typical applications include roughing and semi-finishing passes on ferrous and exotic alloy components in aerospace, energy, and general machining environments.

Key Features

• KC725M grade with TiAlN PVD coating for extended tool life in steel and superalloy milling
• Positive rake angle (20 degrees) and 15-degree relief angle reduce cutting forces on difficult materials
• GE chip breaker with chamfered and honed cutting edge for controlled chip evacuation
• 2 cutting edges, single-sided, right-hand orientation — EDPT parallelogram insert style
• Corner radius of 0.0157 inches (1/64 inch) provides a controlled edge transition
• Screw-held mounting method for positive insert retention in the cutter body
• Compliant with ANSI and ISO standards; compatible with Mill 1-14 cutter series

Compatibility

Compatible with the Mill 1-14 cutter series. Insert conforms to ANSI code EP1404SGE and ISO code EDPT140404PDSRGE. Designed for right-hand, screw-held insert pockets accepting the EDPT 1404 insert size. Primary workpiece materials are steel, stainless steel, superalloys, and titanium.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Disengage spindle power and lock out the machine before handling or indexing inserts. Use the appropriate Torx or hex key per the cutter body manufacturer specification when tightening the clamping screw — do not over-torque, as carbide inserts are brittle. Inspect the insert pocket seat and clamping screw threads for debris or wear before seating a new insert.
