Iscar 2394823 Grooving Cutoff Toolholder Right Hand

Product Description

The ISCAR 2394823 is a right-hand indexable grooving and cut-off toolholder in the PentaCut series, designed for precision groove milling and parting operations on CNC lathes and turning centers. It accepts PENTA 24 series inserts secured by a screw-clamping mechanism, providing rigid, repeatable insert positioning. The toolholder handles groove widths from 0.031 to 0.189 inches and a maximum depth of cut of 0.256 inches. With a shank cross-section of 0.750 by 0.750 inches and an overall length of 4.700 inches, it fits standard toolpost and turret block setups common in production turning environments. Manufactured to ISO 13399 standards, this holder is suited for machinists and toolroom technicians working in high-mix or high-volume turning applications.

This toolholder is appropriate for external grooving, recessing, and cut-off operations on both ferrous and non-ferrous workpieces. The PCH-style body and right-hand orientation suit typical OD turning setups where the tool approaches the workpiece from the front of the turret. Compatible insert size codes include PENTA 24N-J-RS and PENTA 24N-RS/LS, making it straightforward to select insert geometry and grade for the specific material and finish requirement. It is a single-unit item with a minimum order quantity of one, suitable for job shop use or production line tooling inventories.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician with the machine spindle stopped and all axes locked per the machine tool manufacturer's lockout/tagout procedure. Torque the insert clamping screw to the insert manufacturer's specified value using the appropriate Torx or hex key — do not overtighten. Verify tool overhang and shank seating depth against the turret block specification before taking a cut. Inspect the insert pocket and clamping surfaces for chips or debris before each insert change.
