Kennametal 7093266 Tnmg Turning Insert Carbide Altin

Product Description

The KENNAMETAL 7093266 is a TNMG-style triangular carbide turning insert designed for precision metal-cutting operations on CNC lathes and manual turning centers. Built to KCU10B grade carbide and finished with an AlTiN (aluminum titanium nitride) coating, this insert delivers reliable wear resistance and thermal stability during interrupted and continuous turning. The neutral hand orientation suits a wide range of tool holders. With a corner radius of 0.40 mm (0.0157 inches) and a 60-degree included angle, it is suited for finishing and semi-finishing passes where tight tolerances and consistent surface finish are required.

This insert is intended for use in production and job-shop environments where carbide turning inserts are indexed into standard TNMG-compatible tool holders. The triangle insert shape provides six usable cutting edges per insert, reducing tooling cost per edge. Applications include turning of steel, stainless steel, and similar machinable alloys. The FF chip breaker geometry supports controlled chip evacuation at moderate feed rates, making it appropriate for finishing cuts on both external and internal diameters in a machinist or tooling technician workflow.

Installation Notes

This insert is installed and indexed by a qualified machinist or tooling technician. Always power down and lock out the machine before changing inserts. Use the appropriate torque wrench and clamping hardware specified by the tool holder manufacturer when seating the insert. Inspect the insert pocket and clamping screw for wear or damage before indexing to a new cutting edge.
