Iscar 2300730 Indexable Cutoff Blade Tool Block

Product Description

The ISCAR 2300730 is an indexable cutoff blade tool block designed for cut-off operations on CNC lathes and turning centers. Built to the SGTBN tool block style, it accepts Self Grip and Self Grip T-Cut series blades with a compatible blade height of 1.02 inches. The block features a 0.75-inch shank height and 0.75-inch shank width, fitting standard toolpost and turret configurations. Overall length is 3.4 inches. The neutral cutting direction makes it suitable for standard right-hand turning setups. Machinists and toolroom professionals install this block as part of a modular parting and grooving system.

This tool block is used in precision turning applications where repeatable cutoff and grooving performance is required. It is appropriate for both production and job-shop environments running CNC or manual lathes. The SGTBN style integrates with the ISCAR Self Grip blade family, allowing blade changes without removing the block from the turret. Typical applications include parting stock, cutoff of finished parts, and shallow external grooving on ferrous and non-ferrous workpieces.
