Iscar 2300922 Indexable Cutoff Toolholder Right Hand

Product Description

The ISCAR 2300922 is a right-hand indexable cutoff toolholder built for parting and grooving operations on CNC lathes and turning centers. It accepts GTN 3.. and GTR 3.. inserts using a self-grip clamping method, which provides secure insert retention without additional fasteners. The toolholder handles a maximum workpiece diameter of 1.38 inches and accommodates an insert width of 0.122 inches. With an overall length of 4.33 inches and a 0.75-inch shank height, this holder fits a range of standard tool post setups. It is installed by machinists and CNC operators in production and job-shop environments.

This toolholder is suited for cut-off applications in residential shop, production machining, and job-shop settings where repeatable parting of bar stock and turned components is required. The self-grip series design is intended for use on lathes where quick insert indexing reduces downtime. The SGTH toolholder style positions the cutting edge at 0.75 inches back from the bar to the cutting edge, providing clearance for typical parting depths within the 1.38-inch maximum workpiece diameter range. Machinists working with small-diameter bar stock will find the geometry and insert compatibility well suited to tight-tolerance cutoff work.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the lathe or turning center is fully powered down and the spindle is locked before mounting or removing the toolholder. Confirm the tool post slot dimensions match the 0.75-inch shank height and 0.5-inch shank width before tightening. When indexing inserts, follow the insert manufacturer's seating procedure to ensure full engagement with the self-grip pocket.
