Iscar 2800261 Indexable Cutoff Toolholder Right Hand

Product Description

The ISCAR 2800261 is a right-hand indexable cutoff toolholder designed for grooving, parting, and turning operations on CNC lathes and manual turning centers. It accepts GI.. and TIP.. series inserts with a minimum insert width of 0.118 inches and a maximum insert width of 0.157 inches, making it compatible with a range of standard Cut Grip insert geometries. The toolholder features a 0.75 inch square shank (0.75 inches height by 0.75 inches width) and delivers a maximum depth of cut of 0.79 inches. Maximum workpiece diameter capacity is 1.58 inches. Insert retention is achieved via a clamp-style holding method, providing secure, repeatable positioning during interrupted and continuous cuts. The toolholder weighs 0.4 pounds and conforms to ISO 13399 standards for cutting tool data representation.

This toolholder is suited for light to medium-duty cutoff and grooving work on small-diameter bar stock and workpieces up to 1.58 inches in diameter. The GHG-style (toolholder style GHG) head configuration is commonly used in production turning environments where consistent parting and grooving are required. It is a direct fit for CNC turning centers and conventional lathes where a 0.75 inch square shank tool block is used. Machinists and tool-room technicians working with Swiss-style or gang-tooled setups will find the compact head geometry useful for tight-clearance applications. Coolant-through capability is not included on this model.
