Iscar 2301399 Grooving Cutoff Toolholder Left Hand

Product Description

The ISCAR 2301399 is a left-hand indexable grooving and cut-off toolholder from the Do Grip series, designed for precision grooving and parting operations on CNC lathes and turning centers. It accepts DG. 1.. and DG. 3.. series inserts secured by a clamp-style holding method. The toolholder features a 16 x 16 mm square shank and delivers a maximum depth of cut of 16 mm, making it suitable for moderate to deep grooving work. Groove widths range from 3 mm to 3.18 mm. Overall length is 140 mm. This toolholder is installed and set up by machinists and tooling specialists in production and job-shop turning environments.

The 2301399 is intended for grooving and cut-off applications on turned components in both production and general-purpose machining environments. The left-hand orientation suits specific spindle rotation and approach direction requirements on standard CNC lathes. The Do Grip series is engineered for secure insert clamping and consistent radial positioning, which is important in high-cycle grooving operations where insert indexing speed and repeatability matter. The DGT toolholder style is compatible with the DGN, DGNM, DGR, and DGL insert families in the J, JS, and JT seat configurations.
