Kennametal 7097847 Grooving Insert A4R Carbide Altin

Product Description

The KENNAMETAL 7097847 is a carbide grooving insert designed for precision external and internal grooving operations on CNC lathes and turning centers. Built to the A4R style in size code 3, it features a 0.1250 inch cutting width and a maximum depth of cut of 0.1080 inches. The insert is coated with aluminum titanium nitride (AlTiN) via a PVD process under KENNAMETAL grade KCU10B, providing wear resistance and thermal stability at elevated cutting temperatures. It is double-ended with two cutting edges, extending tool life per insert. A full corner radius of 0.0625 inches produces a smooth groove floor, and the positive rake geometry promotes clean chip formation. Licensed machinists and CNC turning specialists install and index this insert.

This insert suits grooving and parting applications in ferrous and non-ferrous materials where tight groove width tolerances are required. The GMN chip breaker geometry is suited to light to medium feeds on small-diameter grooves in general turning applications. It clamps into A4-series KENNAMETAL toolholders using a clamp-style holding method, making it appropriate for both production turning and job-shop environments where repeatable groove geometry is critical. The neutral hand orientation allows use on standard straight-approach grooving setups.

Installation Notes

A qualified machinist or CNC tooling technician should install this insert. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate KENNAMETAL clamp key or torx driver to seat the clamp securely against the insert without overtightening. Inspect the insert pocket and clamp for wear or debris before seating a new insert to ensure proper support and accurate groove geometry.
