Sandvik Coromant 7080837 Turning Insert DNMG442-PM 4335

Product Description

The SANDVIK COROMANT 7080837 is a DNMG442-PM turning insert from the T-Max P series, designed for external turning operations on CNC lathes and turning centers. This solid carbide insert features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which provides wear resistance and thermal stability for continuous and semi-interrupted cuts. The 55-degree diamond shape (insert shape code D) delivers a sharp, precise cutting geometry. With a neutral hand orientation, it suits a wide range of right-hand and left-hand toolholder configurations used by machinists and CNC operators in production turning environments.

This insert is optimized for steel workpieces (ISO material group P) and is a standard choice for medium to finishing passes in general-purpose turning. The PM chip breaker geometry manages chip flow effectively across a range of depths of cut and feed rates. It fits standard DNMG-style toolholders and is used in both job-shop and high-volume production settings. Each package contains one insert, with a minimum order quantity of one.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine before indexing or replacing inserts. Use the correct torque on the clamp screw as specified by the toolholder manufacturer, and inspect the insert seat and pin for wear or debris before seating a new insert. Verify insert orientation and hand before resuming cuts.
