Kennametal 7093484 Dnmg Turning Insert Carbide Altin

Product Description

The KENNAMETAL 7093484 is a DNMG-style indexable turning insert designed for precision external and internal turning operations on CNC lathes and turning centers. This neutral-hand insert is manufactured from carbide substrate with an AlTiN (aluminum titanium nitride) coating and carries the KCU10B manufacturer grade. The diamond-shaped insert geometry features a 55-degree included angle, a 0.40 mm corner radius (1/64 inch), and a 0-degree relief angle. With four available cutting edges per insert, it delivers consistent tool life in moderate to high-speed turning applications. Licensed machinists and CNC operators working in job shop and production environments are the primary installers.

This insert is suited for turning operations requiring a sharp, pointed diamond profile on a variety of workpiece materials. The AlTiN coating provides thermal resistance and wear protection appropriate for dry or minimal-lubrication cutting conditions. The FP chip breaker geometry assists with chip control during finishing and semi-finishing passes. The KCU10B grade is intended for applications where edge toughness and coating durability are priorities. This insert fits toolholders designed for DNMG-style inserts with the corresponding insert size code 431 and clearance code N.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torque wrench and insert clamp screw per the toolholder manufacturer specifications. Inspect the toolholder pocket and clamp for wear or damage before seating a new insert to ensure proper support and clamping force.
