Tungaloy 6808828 Ceramic Turning Insert TPGN222

Product Description

The TUNGALOY 6808828 is a TPGN222 LX11 grade ceramic turning insert designed for high-speed machining of hard materials. It features an alumina TiC substrate with a PVD-applied TiN coating and a flat-top chipbreaker geometry. The insert measures 0.433 inches in length with a 0.25-inch inscribed circle and a 0.0315-inch corner radius. With 3 cutting edges, a 60-degree triangular shape, and a positive rake angle, it is suited for turning, facing, and boring operations where tool life and surface consistency on hard workpieces are the priority. Licensed machinists and CNC tooling technicians are the primary installers.

This insert is intended for machining hard materials, designated under ISO workpiece material code H. Its flat-top, honed cutting edge style and neutral hand orientation make it adaptable across turning, facing, and boring applications. The maximum depth of cut reaches 0.0787 inches. It fits into standard TPGN-style toolholders using a clamp-style holding method, making it compatible with a wide range of production turning setups in both job-shop and high-volume manufacturing environments.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and de-energize the machine tool completely before changing inserts. Seat the insert fully in the toolholder pocket and verify clamp torque with the toolholder manufacturer's guidelines before resuming cuts. Inspect the pocket and clamp for wear or debris that could affect insert seating and dimensional accuracy.
