Iscar 2300765 Indexable Cutoff Blade Tool Block

Product Description

The ISCAR 2300765 is an indexable cutoff blade tool block designed for grooving, parting, and turning operations on CNC lathes and turning centers. Built to the SGTBU tool block style within ISCAR's Self Grip series, it accepts blades with a compatible height of 1.26 inches and a blade width of 0.21 inches. The block features an overall length of 4.33 inches, an overall height of 1.95 inches, and an overall width of 1.75 inches. Through-coolant capability delivers cutting fluid directly to the cutting zone, supporting tool life and chip evacuation during deep grooving and parting operations. The modular, reversible design gives machinists flexibility in setup and orientation. This tool block is installed by machinists and toolroom technicians working with CNC turning equipment.

The 2300765 is suited for production turning environments where accurate, repeatable grooving and parting are required. With a 1.0-inch shank height and a 1.03-inch shank width, it seats firmly in compatible tool posts and turrets. The reversible configuration allows the block to be repositioned without requiring a separate left- or right-hand holder, reducing tooling inventory. Applications include external grooving, cutoff operations, and profile turning on ferrous and non-ferrous workpieces. The through-coolant feature is particularly useful in high-volume production where heat and chip management are critical to maintaining part quality and dimensional consistency.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine before mounting or adjusting the tool block. Ensure the shank seats fully and squarely in the tool post or turret before torquing clamping fasteners. Verify coolant line connections are secure and free of leaks before resuming cutting operations.
