Kennametal 3766023 Milling Insert EDCT10T320PDERLD KC725M

Product Description

The KENNAMETAL 3766023 is a solid carbide milling insert carrying the ISO designation EDCT10T320PDERLD and manufacturer grade KC725M. It features a TiAlN coating applied via PVD process, delivering wear resistance and thermal stability during interrupted or continuous milling operations. The insert has a parallelogram shape with a 70-degree included angle, a positive rake geometry, and an LD chip breaker. With a corner radius of 0.094 inches and a maximum depth of cut of 0.338 inches, it is suited for demanding metal removal in production milling environments. Installation is performed by qualified machinists and CNC operators working with compatible KENNAMETAL Mill 1-10 cutter bodies.

This insert is designed for milling steel, stainless steel, superalloys, and titanium, covering material grades C5, C6, and C7 per ANSI classification. The positive rake and honed cutting edge reduce cutting forces and extend tool life on difficult-to-machine materials. The right-hand orientation and screw-holding method make it a direct-fit solution for compatible toolholders. Typical applications include face milling, shoulder milling, and profile milling operations on machining centers and CNC mills in aerospace, energy, and general metalworking settings.

Installation Notes

This insert is installed by qualified machinists or CNC tooling technicians. Always power down and lock out the machine spindle before changing inserts. Use the correct torx or hex key to torque the clamping screw to the toolholder manufacturer specification — do not overtighten, as carbide inserts are brittle and can fracture under excess clamp load. Inspect the insert pocket and seating surfaces for chips or debris before seating the new insert.
