Iscar 2302886 Grooving Cutoff Toolholder Tang-grip

Product Description

The ISCAR 2302886 is a right-hand indexable grooving and cutoff toolholder from the Tang-Grip series, designed for external turning operations on CNC and manual lathes. It accepts TAG-series inserts and holds them via a clamp-style retention method, providing repeatable positioning and secure insert lock during aggressive grooving or parting passes. The toolholder accommodates a groove width range of 0.110 to 0.138 inches and features a square shank measuring 1.000 inch in height by 1.000 inch in width, with an overall length of 5.905 inches. It is installed by machinists and CNC toolroom technicians setting up turning centers for cutoff and grooving work.

This toolholder is suited for external grooving and cutoff applications on turning centers and engine lathes in both production and job-shop environments. It is intended for use where Tang-Grip TAG inserts are the specified insert family. The TGTR25.4-3-IQ-2Z style designation indicates a right-hand holder configured for 3 mm wide TAG inserts within the compatible size range. No coolant-through capability is present on this holder, making it appropriate for setups that rely on external coolant delivery or dry cutting conditions.

Installation Notes

Installation is performed by a qualified machinist or CNC toolroom technician. Power down and lock out the machine spindle before seating or indexing inserts. Mount the shank securely in the tool block or turret, ensuring full shank contact to minimize overhang deflection during cutoff passes. Verify insert seating and clamp torque according to ISCAR Tang-Grip setup documentation before running the first part.
