Kennametal 2976498 Grooving Cutoff Toolholder Right Hand

Product Description

The KENNAMETAL 2976498 is an indexable grooving and cutoff toolholder designed for external turning operations on CNC lathes and machining centers. Part of the A4 series, this right-hand holder uses a clamp-style insert holding method compatible with A4..02.. inserts. It delivers a minimum groove width of 0.079 inches and a maximum depth of cut of 0.67 inches (17 mm). The 1 x 1 inch square shank seats securely in standard tool blocks, making setup straightforward for production machinists and toolroom technicians running repetitive grooving or parting operations.

This toolholder is suited for external grooving and cutoff applications in production turning environments, including job shops and manufacturing facilities running medium to high volume work. Its A4 series classification and A4..02.. insert compatibility make it a direct fit for shops already standardized on Kennametal A4 series tooling. The right-hand cutting orientation supports conventional lathe setups where the tool approaches the workpiece from the front of the turret.
