Iscar 2301626 Grooving Cutoff Toolholder Left Hand Pentacut

Product Description

The ISCAR 2301626 is a left-hand indexable grooving and cut-off toolholder in the PentaCut series, designed for precision grooving and parting operations on CNC lathes and turning centers. It accepts PENTA 24 series inserts secured by screw clamping, providing repeatable insert location and rigid holding. The toolholder handles groove widths from 0.0197 inches up to 0.125 inches with a maximum depth of cut of 0.256 inches. With a 0.5-inch square shank and an overall length of 5.0 inches, this holder fits standard 0.5-inch tool stations. It is installed and used by machinists and CNC turning specialists in job shops and production environments.

This toolholder is suited for grooving and cut-off applications on both ferrous and non-ferrous workpieces where a left-hand orientation is required. The PCH-style head geometry is optimized for shallow-to-moderate depth grooving passes. The 0.8-inch head length and 4.2-inch shank length support reach into workpiece features while maintaining shank engagement within the turret. Compatible insert profiles cover a wide range of thread forms and groove geometries, making this holder versatile across threading, grooving, and parting operations on a single platform.
