Iscar 2300934 Indexable Cutoff Toolholder Right Hand

Product Description

The ISCAR 2300934 is a right-hand indexable cutoff toolholder designed for parting and grooving operations on CNC lathes and turning centers. Built on the Self Grip series platform, it uses a self-gripping insert-holding method that secures GTN 3.. and GTR 3.. series inserts without additional clamping hardware. The toolholder accepts a minimum insert width of 0.122 inches and handles a maximum depth of cut of 0.98 inches. The 1 x 1 inch square shank fits standard toolpost and turret mounting positions. Licensed machinists and CNC operators install this holder in production and job-shop turning applications.

This toolholder is suited for cut-off work on workpieces up to 2.05 inches in diameter. The SGTH style head and 5.9-inch overall length make it compatible with standard 1 x 1 inch shank toolpost setups on small to mid-size lathes. It is commonly used in high-volume production environments where repeatable parting performance is required on steel, aluminum, and similar turned materials. The Self Grip series design allows for fast insert indexing, minimizing downtime during production runs.
