Kennametal 7093249 Dnmg Turning Insert Altin Carbide

Product Description

The KENNAMETAL 7093249 is a DNMG-style carbide turning insert designed for external turning and profiling operations on CNC and manual lathes. Built to grade KCU10B and coated with AlTiN, this insert delivers wear resistance and thermal stability across a range of cutting conditions. The diamond insert shape provides a 55-degree included angle, and the neutral hand orientation makes it suitable for both left- and right-hand toolholders. Corner radius measures 0.40 mm (0.0157 inches), making it appropriate for general-purpose finishing and semi-finishing passes where tight radii are required. Machinists, tool-and-die technicians, and CNC operators working in job shops and production environments will find this insert a direct-fit replacement for standard DNMG tooling setups.

This insert is suited for turning operations on steel, stainless, and other materials where the KCU10B grade and AlTiN coating provide adequate hardness and oxidation resistance. The MS chip breaker geometry is designed to manage chip flow during medium to light cutting conditions, reducing chip interference and maintaining surface finish quality. It fits standard DNMG-compatible toolholders widely used in both manual and CNC turning centers. Typical applications include external diameter turning, facing, and light profiling. The four available cutting edges per insert maximize tooling economy in production environments.

Key Features

• Four usable cutting edges per insert for extended tooling value in production use

Compatibility

Designed as a direct-fit replacement for standard DNMG-style turning toolholders. Insert size code 331 with clearance code N and tolerance code M; confirm toolholder specifications before ordering.

Installation Notes

Installation should be performed by a qualified machinist or CNC technician with the machine powered down and spindle locked before changing inserts. Use the appropriate torx or clamp-style wrench for the toolholder clamping system — do not overtighten the clamp screw beyond toolholder manufacturer specifications. Inspect the toolholder pocket and shim seat for wear or debris before seating the insert. Verify insert orientation and hand before resuming cutting operations.
