Kennametal 7097853 A4G Grooving Insert 2B Carbide Altin

Product Description

The KENNAMETAL 7097853 is a carbide grooving insert designed for external and internal grooving operations on CNC lathes and turning centers. Built to the A4G insert style in size 2B, this double-end insert features a neutral hand orientation and a PVD-applied AlTiN coating for improved wear resistance and thermal stability at the cutting edge. The KCU10B manufacturer grade paired with a positive rake geometry promotes efficient chip evacuation and reduced cutting forces. With a cutting width of 0.094 inches and a maximum depth of cut of 0.075 inches, it suits precision grooving work in steel, stainless, and similar workpiece materials. Machinists and CNC operators install this insert as a direct replacement in compatible A4-series toolholders.

This insert is suited for use on production turning equipment where consistent groove width and surface finish are required. The double-end configuration provides two usable cutting edges per insert, extending service intervals between changeovers. The GMN chip breaker geometry is intended for medium-duty grooving applications. The neutral hand designation makes it applicable in both right-hand and left-hand tooling setups depending on the holder configuration. It is a replacement-grade insert appropriate for job shops and production facilities running repeat grooving cycles.

Installation Notes

Insert installation and replacement should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before accessing the toolholder. Use the appropriate torque wrench and clamping hardware specified by the toolholder manufacturer when seating the insert. Inspect the insert seat and clamp for wear or debris before installing a new insert to ensure proper seating and edge repeatability.
