Iscar 2302887 Grooving Cutoff Toolholder Tang-grip

Product Description

The ISCAR 2302887 is a right-hand indexable grooving and cut-off toolholder in the Tang-Grip series, designed for external turning operations on CNC lathes and turning centers. It accepts TAG-series inserts and accommodates groove widths from 0.146 to 0.177 inches, making it well suited for precision grooving and parting applications. The shank measures 1 inch by 1 inch in cross-section, with an overall length of 5.905 inches. Inserts are secured by a clamp-style holding method, providing positive engagement and repeatable positioning under heavy interrupted cuts. Licensed machinists and CNC operators working in production turning environments are the primary users of this holder.

This toolholder is used in external grooving and cut-off operations on bar stock and turned components in both job-shop and production settings. The Tang-Grip design is commonly found on CNC turning centers handling steel, stainless, cast iron, and non-ferrous materials where clean groove geometry and stable insert seating are required. The right-hand orientation suits standard-direction spindle setups. No coolant-through capability is present on this holder, so external coolant delivery should be arranged at the machine setup stage.

Installation Notes

This toolholder is installed by a qualified CNC machinist or toolroom technician. Power down and lock out the machine spindle before mounting or changing the holder or inserts. Seat the shank fully in the turret or tool block and torque clamping fasteners per the machine tool builder specifications. Inspect insert pockets and clamping surfaces for chips or debris before seating a new insert to avoid seating errors and premature edge failure.
