Iscar 2301390 Grooving Cutoff Toolholder Right Hand

Product Description

The ISCAR 2301390 is a right-hand indexable grooving and cutoff toolholder in the Do Grip series, designed for external grooving and parting operations on CNC lathes and turning centers. It accepts DG. 1.. and DG. 2.. series inserts secured by a clamp-style holding method, providing rigid insert retention during interrupted cuts and high-feed passes. The square shank measures 16 mm x 16 mm with an overall length of 140 mm, fitting standard lathe tool blocks and quick-change turrets. Compatible insert size codes include DGN/DGNM-J/JS/JT and DGR/L-J/JS. The toolholder handles groove widths from 1.9 mm to 2.5 mm and a maximum depth of cut of 16 mm, covering a wide range of groove profiles in a single holder body.

This toolholder is suited for production turning environments where consistent groove geometry and reliable insert indexing are required. Typical applications include external grooving, parting off, and profile grooving on ferrous and non-ferrous workpieces. The Do Grip series is a common choice for job shops and production facilities running medium to high-volume turning operations. Coolant-through capability is not provided on this model, so external coolant delivery should be used when cutting heat-sensitive materials or working at elevated surface speeds.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the machine in a fully de-energized and locked-out state before toolholder changes. Seat the shank squarely in the tool block and torque all clamping bolts to the machine or tool block manufacturer specifications. Verify insert seating and clamp engagement before resuming spindle operation. External coolant positioning should be confirmed prior to cutting, as this holder does not include internal coolant-through delivery.
