Kennametal 2976497 Grooving Cutoff Toolholder Right Hand

Product Description

The KENNAMETAL 2976497 is a right-hand indexable grooving and cutoff toolholder designed for external grooving operations on CNC lathes and turning centers. Built to the A4SM toolholder style, it accepts A4..02.. series inserts secured by a clamp-style holding method for rigid, repeatable cutting performance. The holder features a 3/4 x 3/4 inch square shank and supports a minimum groove width of 0.079 inches with a maximum depth of cut of 17 mm (0.670 inches). Machinists and CNC operators working in production turning environments install this holder for precise grooving and parting operations on a range of workpiece materials.

This toolholder is suited for external grooving and cutoff applications on conventional and CNC turning equipment. The 3/4 x 3/4 inch shank dimensions make it compatible with standard tool blocks and turret positions on mid-size lathes. At 127 mm (5.000 inches) overall length with a shank length of 92 mm (3.622 inches), it fits standard tooling envelopes without requiring extended-reach adapters. No coolant-through capability is present, so flood or mist coolant should be directed externally at the cutting zone during grooving operations.
