Iscar 2301617 Grooving Cutoff Toolholder Left Hand Pentacut

Product Description

The ISCAR 2301617 is a left-hand indexable grooving and cut-off toolholder in the PentaCut series, designed for precision groove width control and clean parting operations on CNC lathes and turning centers. The PCH-style holder accepts PENTA 24 series inserts secured by screw clamp, providing a stable, repeatable insert seat. Groove width range spans 0.0197 to 0.125 inches with a maximum depth of cut of 0.256 inches. The shank measures 0.75 inches in height and width and 5 inches in overall length, making it compatible with standard 0.75-inch bore tooling blocks and quick-change systems. Weight is 0.35 pounds. Coolant-through is not supported on this holder. Manufactured to ISO 13399 standards for tool data representation.

This toolholder is suited for external grooving and parting operations in production turning environments, including both high-volume and precision short-run applications. The left-hand orientation positions the cutting edge for specific spindle rotation and approach direction requirements. Compatible insert grades and geometries in the PENTA 24 family cover a wide range of materials and thread-form profiles, giving machinists flexibility across different part programs without changing the holder body.
