Mitsubishi 802409 Cnmg Carbide Turning Insert Pvd

Product Description

The MITSUBISHI 802409 is a CNMG-style carbide turning insert designed for precision metal cutting on CNC lathes and turning centers. It features a rhombic insert shape with an 80-degree included angle and a 0.80 mm (0.0312 inch) corner radius, making it suitable for general-purpose turning, profiling, and finishing operations. The insert carries a PVD coating in the MP9005 manufacturer grade, which supports wear resistance and thermal stability during continuous and interrupted cuts. Four cutting edges are available per insert, maximizing tool life and cost efficiency per edge. The insert has a neutral hand orientation and is intended for installation by machinists and CNC tooling professionals.

This insert is suited for use in a wide range of turning applications across industries including aerospace, automotive, and general machining. The CNMG geometry with MS chip breaker designation supports chip control in medium cutting conditions. It fits toolholders designed for CNMG insert pockets with a 0.5000 inch (12.70 mm) inscribed circle and 3/16 inch (0.1875 inch) insert thickness. It performs in both roughing and semi-finishing passes depending on feed and depth of cut parameters selected for the material being turned.

Installation Notes

CNMG inserts are installed by qualified machinists or CNC tooling technicians. Always power down and lock out the machine before changing inserts. Use the correct torx or clamp screw driver to seat the insert firmly in the toolholder pocket without over-torquing. Inspect the insert seat and shim for damage before installing a new insert to ensure proper seating and edge geometry.
