Iscar 2301288 Indexable Cutoff Toolholder Right Hand

Product Description

The ISCAR 2301288 is a right-hand indexable cutoff toolholder designed for grooving, parting, and turning operations on CNC lathes and turning centers. Built to the Do Grip series standard, it accepts DG. 4.. and GRIP 4.. style inserts using a self-grip insert holding method. The shank measures 0.75 inches in height and 0.75 inches in width, with a shank length of 3.25 inches and an overall length of 4.5 inches. It handles workpieces up to 2 inches in diameter, making it well suited for light to medium-duty cutoff work on small-diameter bar stock. Conforms to ISO 13399 tooling data standards.

This toolholder is used in production turning environments where repeatable insert indexing and rigid clamping are required for parting and grooving operations. The DGT toolholder style positions the cutting edge 0.75 inches from the back of the bar, and the 0.134-inch blade width minimizes material loss at the cut. Typical applications include cutoff operations on bar-fed lathes in job shops, production machining cells, and repair machine shops. Machining technicians and CNC setup personnel are the primary installers.
