Kennametal 7093479 Cnmg Turning Insert Altin Carbide

Product Description

The KENNAMETAL 7093479 is a CNMG-style carbide turning insert designed for precision metal cutting on CNC lathes and turning centers. It features an AlTiN (aluminum titanium nitride) coating over a carbide substrate in Kennametal grade KCU10B, delivering heat resistance and wear performance in demanding turning applications. The insert has a diamond shape with an 80-degree included angle, a neutral hand orientation, and a corner radius of 0.0313 inches (0.80 mm). With four cutting edges available per insert, it offers efficient cost-per-edge economics for production turning environments. Machinists, toolroom technicians, and CNC operators working in metalworking shops are the primary users of this insert.

This insert is suited for external and internal turning operations on a range of workpiece materials where AlTiN coatings provide thermal protection at elevated cutting speeds. The CNMG designation indicates a diamond insert shape with a neutral-hand chipbreaker configuration using the RP chipbreaker style. The insert size code is 432, with a width of 0.1875 inches (4.77 mm) and an insert thickness of 0.1875 inches (4.76 mm). It is sold individually per package with a minimum order quantity of 5 units, making it appropriate for both toolroom stocking and production replenishment.

Key Features

• AlTiN coating on KCU10B carbide substrate for extended tool life in high-temperature cutting
• Diamond insert shape with 80-degree included angle for versatile profiling and turning
• Four usable cutting edges per insert for reduced cost per edge
• RP chipbreaker geometry for controlled chip evacuation during turning
• Neutral hand orientation compatible with standard CNMG toolholders
• Corner radius of 0.0313 inches (0.80 mm) for general-purpose finishing and semi-finishing passes

Compatibility

Designed as an OEM-style replacement insert for use in standard CNMG-style turning toolholders accepting a size 432 insert. Consult your toolholder documentation to confirm seat geometry, clamp style, and insert size code compatibility before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC toolroom technician with the machine powered down and in a safe, locked-out state before any tool change. Seat the insert firmly against the toolholder pocket and torque the clamping screw according to the toolholder manufacturer specifications. Inspect the insert seat and clamp for debris or wear before seating a new insert, as contamination can affect insert stability and surface finish. Verify tool offset data in the CNC control after any insert change before resuming cuts.
