Kennametal 2383555 Milling Insert KC725M Solid Carbide

Product Description

The KENNAMETAL 2383555 is a solid carbide milling insert with ISO designation SDCT120404PDERLD2, designed for use in indexable milling toolholders on CNC and manual machining centers. This right-hand insert features a square shape with a 90-degree included angle, a 0.0157-inch corner radius, and a tri-layer PVD coating of TiN, TiCN, and TiN that improves wear resistance and surface finish. The KC725M grade is engineered for cutting steel, stainless steel, superalloys, and titanium. Holding is via screw clamp, and the LD2 chip breaker geometry supports controlled chip evacuation across a range of depths of cut and feed rates.

This insert is suited for face milling, shoulder milling, and general-purpose milling operations in production and job-shop environments. It is appropriate for aerospace, energy, and general manufacturing applications where steel and difficult-to-machine alloys are the primary workpiece materials. The insert is sold individually per package with a minimum order quantity of 5 units. Machinists and tooling specialists specify this insert when the KC725M grade and SDCT series geometry are called out for the application.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the machine spindle is fully stopped and locked out before indexing or replacing inserts. Use the correct torx or hex key to the toolholder manufacturer's specified seating procedure when clamping the insert screw. Inspect the toolholder pocket and clamp for wear or debris before seating the new insert to ensure proper contact and runout.
