Kennametal 5980917 Grooving Cutoff Toolholder Right Hand

Product Description

The KENNAMETAL 5980917 is an external indexable grooving and cutoff toolholder in the Beyond Evolution series, designed for precision groove turning on CNC lathes and turning centers. It accepts EG0400M04P04 inserts secured by a clamp-style holding method, delivering a fixed groove width of 4 mm (0.158 inches) with a maximum depth of cut of 26 mm (1.024 inches). The 1 x 1 inch square shank fits standard OD toolholder pockets, and integrated through-coolant capability directs fluid directly to the cutting zone for improved chip evacuation and insert life. Licensed machinists and CNC operators install this holder in production turning applications where consistent groove geometry and depth are required.

This toolholder is suited for external grooving and parting operations on lathes running steel, stainless, cast iron, and similar workpiece materials. The EVSC-T style head geometry positions the cutting edge for right-hand operation with the spindle running in standard forward rotation. Through-coolant delivery makes it well suited for deep grooving passes where heat buildup and chip packing are common concerns. It is a direct-replacement-style holder for shops already running the Beyond Evolution system.

Compatibility

Compatible with EG0400M04P04 indexable grooving inserts. Part of the KENNAMETAL Beyond Evolution series using mount size 1616. Designed for use in external OD grooving and cutoff applications on CNC lathes and turning centers equipped with through-coolant toolholder pockets.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Power down and lock out the machine spindle before mounting or removing the toolholder. Verify that the toolholder pocket and shank contact surfaces are clean and free of chips before torquing the holder bolts to the machine specification. Confirm through-coolant port alignment with the machine turret coolant supply before running the first cycle.
