Kennametal 7090633 Vnmg Turning Insert Altin Carbide

Product Description

The KENNAMETAL 7090633 is a VNMG-style carbide turning insert designed for precision lathe operations on CNC and manual turning centers. Manufactured in a diamond (V) shape with a 35-degree included angle and a 0.80 mm (0.0313 inch) corner radius, this insert delivers sharp, controlled cuts on a wide range of workpiece materials. The KCU10B grade substrate is coated with AlTiN (aluminum titanium nitride) for extended tool life at elevated cutting temperatures. With four usable cutting edges per insert, it offers a cost-effective solution for production turning environments where consistent edge geometry and finish quality are required.

This insert is suited for external and internal turning applications in both ferrous and non-ferrous materials. The neutral hand orientation makes it compatible with standard VNMG toolholders used in production shops, job shops, and maintenance machining environments. The UP chip breaker geometry is optimized for controlled chip formation during finishing and semi-finishing passes. Machinists and CNC programmers working with tight tolerances will find the M tolerance class and N clearance code consistent with standard VNMG insert specifications.

Compatibility

Designed as an OEM-style replacement insert for standard VNMG-style turning toolholders used in CNC and manual lathe applications.

Installation Notes

VNMG turning inserts are seated and secured by qualified machinists or CNC tooling technicians following machine tool manufacturer guidelines. Always power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque wrench and clamping screw specified by the toolholder manufacturer to avoid insert rocking or premature edge failure. Inspect the toolholder pocket and clamping components for wear or damage before seating a new insert.
