Mitsubishi 802556 Dnmg Carbide Turning Insert 0.40mm

Product Description

The MITSUBISHI 802556 is a DNMG-style carbide turning insert designed for precision metal cutting on CNC lathes and turning centers. It features a rhombic insert shape with a 55-degree included angle, a 0.40mm (0.0156 inch) corner radius, and a PVD coating applied over a carbide substrate in the MP9015 grade. The neutral hand orientation makes it adaptable to a wide range of turning tool holders. With four available cutting edges per insert, this indexable insert delivers consistent performance across roughing and finishing passes in general-purpose turning applications.

This insert is suited for external and internal turning operations in both production and job-shop environments. The MP9015 grade with PVD coating is engineered for applications involving steel and other ferrous materials where edge integrity and wear resistance are priorities. It is typically installed by machinists and CNC operators working on horizontal and vertical turning centers. The DNMG geometry with LS chip breaker designation supports effective chip control across a range of depths of cut and feed rates.

Installation Notes

Installation is performed by machinists or CNC operators following standard indexable insert replacement procedures. Power down and lock out the machine spindle before indexing or replacing any cutting insert. Use the appropriate torque wrench and insert clamp screw specified by the tool holder manufacturer — do not over-torque the clamping screw. Inspect the insert pocket for debris or damage before seating the new insert.
