Product Description

The ISCAR 2301923 is a left-hand indexable grooving and cut-off toolholder from the Tang-Grip series, designed for external grooving operations on CNC lathes and turning centers. It accepts TAG 3 inserts secured by a clamp-style holding method, providing rigid, repeatable insert positioning during cut-off and grooving passes. The toolholder handles groove widths from 2.8 to 3.5 mm and a maximum depth of cut of 16 mm. The shank measures 0.5 inches square, making it compatible with standard turning tool blocks and quick-change toolposts. Overall length is 5.91 inches. This toolholder is intended for use by machinists and CNC turning professionals in production and job-shop environments.

The 2301923 is suited for external grooving and cut-off applications on turned workpieces in both production and short-run environments. The left-hand orientation makes it appropriate for specific spindle direction and toolpost position requirements. Compatible insert codes span a range of TAG 3 geometries including TAG N-A, TAG N-C/W/M, TAG N-J/JS/JT, TAG N-LF, TAG N-UT, TAG R/L-C, and TAG R/L-J/JS, allowing the operator to select the appropriate insert edge geometry for the material and finish requirement. Coolant-through capability is not available on this holder.
