Kennametal 7093247 Dnmg Turning Insert Altin Carbide

Product Description

The KENNAMETAL 7093247 is a DNMG-style carbide turning insert designed for precision metal-cutting operations on CNC lathes and turning centers. This insert features an AlTiN (aluminum titanium nitride) coating over a KCU10B carbide substrate, providing elevated heat resistance and wear protection during interrupted and continuous turning. The diamond insert shape (55-degree included angle) with a 0.40mm (0.0157 inch) corner radius suits finish and semi-finish turning where tight tolerances and surface finish matter. A neutral hand orientation allows flexible toolholder compatibility. Four cutting edges per insert extend usable tool life. Licensed machinists and CNC operators in job shops and production machining environments are the primary installers.

This insert is suited for turning applications on steel, stainless steel, and similar workpiece materials where an AlTiN coating provides thermal and abrasion resistance. The FP chip breaker geometry supports controlled chip evacuation during medium-depth finishing passes. The DNMG style fits standard DNMG-compatible toolholders used in both manual and CNC turning setups across light to medium material removal applications in production and job shop environments.

Key Features

• AlTiN coating over KCU10B carbide grade for heat and wear resistance
• Diamond insert shape with 55-degree included angle for profiling and finishing
• 0.40mm (0.0157 inch) corner radius for finish and semi-finish turning
• Four usable cutting edges per insert
• FP chip breaker geometry for controlled chip evacuation
• Neutral hand orientation for versatile toolholder pairing

Compatibility

Designed as an OEM-style replacement insert for standard DNMG-compatible turning toolholders with a 3/16 inch insert seat width and N-clearance, M-tolerance designation.

Installation Notes

Installation is performed by machinists using standard insert-seating tools and torque wrenches appropriate to the toolholder manufacturer specifications. Always index or replace inserts with the machine fully stopped and in a safe, locked-out state. Inspect the toolholder pocket for wear or debris before seating a new insert. Follow the toolholder manufacturer torque guidelines for the clamping screw to avoid insert cracking or improper seating.
