Kennametal 7096819 Grooving Insert A4R Carbide

Product Description

The KENNAMETAL 7096819 is a carbide grooving insert designed for precision grooving and parting operations on CNC lathes and turning centers. Built to the A4R style with a size 4 designation, this insert delivers a 0.1570-inch cutting width and handles a maximum depth of cut of 0.1380 inches. The insert carries a manufacturer grade of KCU10B and features an AlTiN coating applied via PVD process, providing thermal resistance and edge durability in interrupted cuts and general-purpose turning applications. It is installed by machinists and toolroom technicians in production and job-shop environments.

This insert is suited for grooving, recessing, and parting on ferrous and non-ferrous workpieces in both production and repair-shop turning setups. The neutral hand orientation makes it appropriate for straight-in grooving passes. With two cutting edges and a double-end configuration, the insert supports tool life efficiency in high-cycle operations. The full-radius corner geometry with a 0.0783-inch corner radius is well-suited for O-ring groove profiles and radius-bottom groove forms where consistent corner geometry is required.

Installation Notes

Installation should be performed by a qualified machinist with the machine in a full stop condition and all spindle rotation confirmed off before accessing the toolholder. Use the appropriate torx or hex key as specified by the toolholder manufacturer when seating the clamp. Inspect the insert pocket and clamp for debris or wear before loading a new insert. Never exceed the maximum depth of cut rating for the insert grade in a single pass.
