Iscar 2301256 Grooving Cutoff Toolholder 16x16mm Do Grip

Product Description

The ISCAR 2301256 is a right-hand indexable grooving and cut-off toolholder in the Do Grip series, designed for use on CNC lathes and turning centers where precise external grooving and parting operations are required. It accepts DG. 1.. and DG. 3.. series inserts and is held by a clamping method that locks inserts securely under cutting load. The toolholder accommodates groove widths from 3.00 mm to 3.18 mm, with a 16 x 16 mm square shank and an overall length of 150.00 mm. It conforms to ISO 13399 tooling data standards.

This toolholder is suited for external grooving and cut-off applications in production turning environments, including both high-volume and job-shop settings. The right-hand orientation positions the cutting edge for standard front-facing lathe operations. Compatible insert codes include DGN-LF/LFT, DGN-MF, DGN-P, DGN-UT/UA, DGN-WP, DGN-Z, DGN/DGNC/DGNM-C, DGN/DGNM-J/JS/JT, DGR-P, DGR-WP, DGR-Z/ZS, DGR/L-C, DGRC/LC-C, and DGR/L-J/JS, providing a wide selection of geometry and coating options for different workpiece materials.

Installation Notes

Installation is performed by a machinist or toolroom technician on a CNC or manual lathe equipped with a tool post or turret accepting a 16 x 16 mm shank. Power down and lock out the spindle before changing inserts or seating the toolholder. Ensure the insert pocket and clamping surfaces are clean and free of chips before seating a new insert. Verify shank clamp torque per your machine tool manufacturer's specifications and confirm tool overhang does not exceed recommended limits for the shank size.
