Kennametal 1180890 Milling Insert CDE322L05 KC725M Carbide

Product Description

The KENNAMETAL 1180890 is a solid carbide milling insert carrying ISO designation CDE322L05 and manufacturer grade KC725M. It features a PVD-applied TiN/TiCN/TiN multilayer coating that provides wear resistance and thermal stability during interrupted and continuous milling cuts. The insert has an 80-degree included angle, a left-hand cutting orientation, and a 1/32-inch (0.0313-inch) corner radius. Thickness is 0.1500 inches and length is 0.5110 inches. The screw-hole diameter measures 0.1701 inches. Solid carbide construction in grades C5, C6, and C7 makes this insert suited for demanding material removal applications.

This insert targets milling operations in steel, stainless steel, superalloys, and titanium, covering ISO workpiece material codes P, M, and S. It is designed for use in CDE-series milling toolholders requiring a 322-size left-hand parallelogram insert. Typical applications include face milling, shoulder milling, and profile milling on CNC machining centers in production shops, tool rooms, and contract manufacturing environments. Licensed machinists and CNC operators are the primary end users.

Key Features

• KC725M grade solid carbide substrate rated for C5, C6, and C7 material classifications
• Left-hand cutting geometry — confirm toolholder hand before ordering
• 80-degree included angle parallelogram shape (CDE insert style)
• Corner radius of 0.0313 inches (0.80 mm) for controlled surface finish
• Screw-held mounting with 0.1701-inch hole diameter for secure clamping

Compatibility

Designed for use in CDE-series milling toolholders accepting a 322-size left-hand parallelogram solid carbide insert with a 0.1701-inch screw-mount hole. Compatible with workpiece materials including steel, stainless steel, superalloys, and titanium (ISO P, M, S designations).

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the spindle drive before changing inserts. Use the correct torque wrench and the toolholder manufacturer's specified clamping screw to secure the insert — do not overtighten. Verify insert hand (left) matches the toolholder pocket orientation before seating the insert.
