Iscar 2301426 Grooving Cutoff Toolholder Left Hand

Product Description

The ISCAR 2301426 is a left-hand indexable grooving and cutoff toolholder in the Do Grip series, designed for precision groove machining and part cutoff operations on CNC lathes and turning centers. It accepts DG. 1.. and DG. 2.. series inserts secured by a clamp-style holding method, providing rigid, repeatable insert positioning. The toolholder accommodates a groove width range of 0.075 to 0.098 inches and delivers a maximum depth of cut of 0.689 inches. With a shank height and width of 0.750 inches and an overall length of 5.500 inches, this holder fits standard square-shank toolpost and turret positions common in production turning environments.

This toolholder is suited for external grooving, undercutting, and cutoff applications in both job shop and production turning settings. The left-hand orientation positions it for specific turret stations or part configurations where a right-hand holder would interfere. It is designed for use with ferrous and non-ferrous workpiece materials where controlled groove width and depth are required. Machinists and CNC setup technicians in precision machining shops are the primary installers and users of this toolholder.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the turret or toolpost is in a safe, indexed position before mounting or removing the toolholder. Verify the shank bore and toolpost slot match the 0.750-inch shank dimensions before tightening. Insert clamping screws should be tightened with the appropriate torx or hex key per the insert manufacturer tooling guidelines; do not overtighten.
