Iscar 2301900 Grooving Cutoff Toolholder Right Hand

Product Description

The ISCAR 2301900 is a right-hand indexable grooving and cutoff toolholder from the Tang-Grip series, designed for external grooving and parting operations on CNC lathes and turning centers. It accepts TAG 2 inserts secured by a clamp-style holding method, supporting groove widths from 1.8 to 2.5 mm and a maximum depth of cut of 14 mm. The shank measures 0.375 inches square, and the overall length is 5.906 inches (150 mm). This toolholder is intended for use by machinists and CNC turning technicians in production and job-shop environments.

This toolholder suits external grooving and cutoff applications on small to mid-size turned components where precise groove width control is required. The Tang-Grip clamping system provides rigid insert seating, which is important for maintaining dimensional accuracy during parting and profile grooving. It is commonly applied in industries such as automotive, aerospace, and general precision machining where repeatable groove geometry is critical. No coolant-through capability is present on this holder.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Before mounting or changing inserts, ensure the machine spindle is fully stopped and the machine is placed in a safe, locked-out state per applicable shop safety procedures. Seat the shank securely in the toolpost or turret to the full shank depth to minimize overhang and chatter. Follow the insert manufacturer torque guidelines for the clamping screw when seating TAG 2 inserts.
