Iscar 2300849 Indexable Cutoff Toolholder Right Hand

Product Description

The ISCAR 2300849 is a right-hand indexable cutoff toolholder designed for grooving, parting, and turning operations on CNC lathes and manual turning machines. Built to the SGTF toolholder style, it accepts a range of GFN and GFR/L series inserts using a Self Grip clamping method that secures the insert without additional screws or clamps. The shank measures 0.75 inches in both height and width, and the overall length is 4.5 inches. Maximum workpiece diameter is 1.75 inches. Compatible insert widths range from 0.106 inches to 0.139 inches. This holder is built to ISO 13399 standards and is intended for use by machinists and tooling technicians in production turning environments.

This toolholder is suited for light to medium-duty cutoff and grooving work on workpieces up to 1.75 inches in diameter. Typical applications include parting off turned components, external grooving, and profiling passes where a rigid, repeatable insert seat is required. The right-hand orientation positions the cutting edge for standard front-tool-post setups on most engine lathes and CNC turning centers. The Self Grip series design allows fast insert indexing without the use of a separate clamping screw, reducing downtime during insert changes on production runs.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Before changing inserts or mounting the holder, ensure the machine spindle is fully stopped and all power is locked out per shop lockout/tagout procedures. Secure the shank in the tool post or turret to the appropriate clamping torque specified by the machine tool manufacturer — do not over-extend the holder beyond recommended overhang for the workpiece diameter. Verify insert seating fully in the Self Grip pocket before initiating a cut.
