Iscar 2300935 Indexable Cutoff Toolholder Right Hand

Product Description

The ISCAR 2300935 is a right-hand indexable cutoff toolholder designed for parting and cut-off operations on lathes and turning centers. Built to the Self Grip series standard with a SGTH toolholder style, it accepts GTN 4.. and GTR 4.. series inserts using a self-grip insert-holding method. The holder delivers a maximum depth of cut of 1.1 inches and accommodates workpiece diameters up to 2.44 inches, making it well suited for small to medium bar stock applications. The overall length is 5.9 inches with a shank height and width of 1 inch each. Weighing 1.33 pounds, this holder is built for rigid, repeatable indexing in production turning environments.

This toolholder is used in cut-off and parting operations on CNC lathes and manual turning machines where clean, controlled separation of bar stock is required. The self-grip clamping system secures the insert without additional fasteners, allowing for fast insert changes on the shop floor. It is intended for use by machining professionals and toolroom technicians working with steel, aluminum, and similar machinable materials in both job shop and production settings.
