Tungaloy 6772260 Dnmg 432 Tm T9215 Turning Insert

Product Description

The TUNGALOY 6772260 is a DNMG 432 TM indexable turning insert in grade T9215, designed for external and internal turning operations on CNC lathes and turning centers. Built from solid carbide with a CVD-applied multilayer coating sequence of TiCN, Al2O3, and TiN, this insert delivers thermal resistance and wear protection across a range of cutting conditions. The insert carries a 55-degree diamond shape, a negative rake angle of -6 degrees, and a 0.0315-inch corner radius, making it suitable for medium-stock-removal passes where edge stability and surface finish both matter. It features 4 cutting edges per insert and a TM chip breaker geometry. Licensed machinists and CNC operators install this insert in standard DNMG-style toolholders.

This insert is rated for turning, facing, boring, back turning, and back boring applications. Primary workpiece materials are steel, stainless steel, and cast iron, corresponding to ISO material codes P, M, and K. Material grades P10 and P20 apply, positioning this insert for light-to-medium roughing and semi-finishing cuts in ferrous materials. It fits both clamped and pin-lock style DNMG toolholders. Residential and industrial machine shops, production turning cells, and job shops running steel and stainless components are the typical environments for this insert.

Key Features

Compatibility

Designed as an OEM-style replacement for DNMG 432 TM toolholders that accept clamp or pin-lock holding methods. Compatible with steel, stainless steel, and cast iron workpieces in turning, facing, boring, back turning, and back boring operations.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before seating or indexing inserts. Ensure the insert pocket and seat are clean and free of chips before clamping to maintain correct insert positioning. Follow toolholder manufacturer torque and clamping specifications for the specific toolholder body in use.
