Iscar 2300813 Indexable Cutoff Toolholder Left Hand

Product Description

The ISCAR 2300813 is a left-hand indexable cutoff toolholder designed for grooving, parting, and turning operations on CNC lathes and turning centers. Built to the Self Grip series standard, it accepts a range of GFN and GFR/L inserts secured by a self-gripping clamping method that eliminates the need for a separate clamping screw. The toolholder accommodates workpieces up to 2.25 inches in diameter and accepts inserts with widths from 0.106 inches minimum to 0.139 inches maximum. The shank measures 1 inch in height and 1 inch in width, with an overall length of 5.9 inches. Licensed machinists and CNC operators install this holder in production and job-shop turning applications where repeatable insert indexing and rigid cutoff performance are required.

This toolholder is suited for residential and commercial machine shops running high-volume parting and grooving cycles. It is typically mounted in a square-shank tool block or turret station on a CNC or manual lathe. The left-hand orientation positions the cutting edge for specific approach directions in turret configurations. Compatible insert codes GFN-A, GFN-C, GFN-J, GFN-M, GFN-U, GFN-W, GFR/L-C, GFR/L-J, GFR/L-W, and GFR-U are supported, giving operators flexibility across different grooving and parting profiles. The ISCAR catalog reference for this holder is SGTFL 25.4-3. It meets ISO 13399 tooling data standards for compatibility with CAM and tool management systems.
