Kennametal 7108886 Cnmg Turning Insert Carbide Altin

Product Description

The KENNAMETAL 7108886 is a CNMG-style indexable turning insert designed for precision external turning operations on CNC lathes and turning centers. This carbide insert features an AlTiN (aluminum titanium nitride) coating on a KCU10B grade substrate, providing excellent wear resistance and thermal protection during high-speed cutting. The insert has an 80-degree diamond shape with a neutral hand orientation, 4 usable cutting edges, and a 0.0313-inch corner radius. It measures 0.1875 inches in thickness and width. Machinists and tool-and-die professionals use this insert for general turning of ferrous and difficult-to-machine materials where edge retention and surface finish consistency are critical.

This insert is suited for medium to finish turning passes in production and job-shop environments. The FP chip breaker geometry supports controlled chip formation across a range of feed rates and depths of cut. The CNMG form factor fits standard CNMG-style insert pockets on compatible turning toolholders. With 4 indexable cutting edges per insert, it delivers consistent performance across multiple setups before replacement is needed.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and the turret is locked before indexing or replacing inserts. Use the correct torque wrench and insert screw specified by the toolholder manufacturer when seating the insert. Inspect the insert pocket seat and clamp for wear or debris before installation to ensure proper seating and edge repeatability.
