Iscar 2800551 External Lh Indexable Grooving Toolholder

Product Description

The ISCAR 2800551 is an external left hand indexable grooving toolholder in the Cut Grip series, designed for precision grooving operations on CNC lathes and turning centers. It accepts a range of GIG, GIM, GIP, and TIP insert styles, offering flexibility across multiple groove width requirements. The toolholder features a 0.5 inch by 0.5 inch square shank and an overall length of 4.72 inches. Maximum depth of cut is 1 inch, with groove width capability ranging from 0.087 inches to 0.124 inches. The GHS toolholder style uses a clamp-type insert holding method for secure, repeatable insert seating under production conditions.

This toolholder is suited for external grooving applications on a wide range of workpiece materials, classified under ISO material groups H, K, M, N, P, and S. It is intended for use in professional machining environments where left hand cutting direction and external groove profiles are required. Typical applications include OD grooving, snap ring grooves, and undercut operations on turned components. The 1 inch maximum workpiece diameter and 0.464 inch back-of-bar to cutting edge dimension make it well matched to smaller-diameter turning work. It does not support coolant-through delivery.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Before mounting or changing inserts, ensure the machine spindle is fully stopped and the control is in an e-stop or locked-out state per your facility lockout/tagout procedure. Seat the shank securely in the turret or tool block, verify insert seating before initiating a cut, and confirm that the left hand cutting direction matches the programmed tool path and spindle rotation of the setup.
