Kennametal 7093318 Dnmg Carbide Turning Insert

Product Description

The KENNAMETAL 7093318 is a DNMG-style carbide turning insert designed for precision external turning operations on CNC lathes and manual turning centers. Manufactured from carbide with an AlTiN (aluminum titanium nitride) coating, this insert is built for wear resistance in demanding cutting applications. It carries a KCU10B manufacturer grade, a neutral hand orientation, and an FP chip breaker geometry. With a 55-degree included angle and a 0.0313-inch corner radius, this insert suits general-purpose profiling and turning where a sharp diamond profile is required. Licensed machinists and CNC operators working in production environments are the primary users.

This insert fits standard DNMG toolholders and is appropriate for turning ferrous and non-ferrous workpiece materials in production and job-shop environments. The FP chip breaker promotes reliable chip control across a range of depths of cut and feed rates. The AlTiN coating supports higher cutting speeds and elevated temperatures compared to uncoated carbide grades, making it well suited for dry or minimal-lubrication cutting strategies. Four available cutting edges per insert help reduce tooling cost per edge in high-volume turning operations.

Key Features

• DNMG insert style with 55-degree diamond shape for profiling and general turning
• KCU10B carbide grade with AlTiN coating for extended tool life at elevated temperatures
• FP chip breaker geometry for consistent chip control across moderate feeds and depths
• Neutral hand orientation fits standard DNMG right-hand and left-hand toolholders
• Four cutting edges per insert maximize cost efficiency per edge
• 0.0313-inch corner radius supports fine-to-medium surface finish requirements

Compatibility

Designed as an OEM-style replacement insert for standard DNMG-style turning toolholders accepting a 4.76 mm thick diamond insert with clearance code N and tolerance code M.

Installation Notes

DNMG inserts are seated and clamped by a licensed machinist or CNC toolroom technician following the toolholder manufacturer's torque and clamping procedures. Power down and lock out the machine spindle before changing inserts. Inspect the insert pocket and clamping screw for debris or damage before seating a new insert. Do not mix insert grades or geometries within the same operation without verifying compatibility with the toolholder and workpiece material.
