Iscar 2800269 Grooving Cutoff Toolholder Right Hand

Product Description

The ISCAR 2800269 is an indexable grooving and cutoff toolholder in the Cut Grip series, designed for external turning operations on CNC and manual lathes. It accepts GI.. series inserts and uses a clamp-style insert holding method for secure, repeatable edge positioning. The toolholder features a right-hand orientation, a shank measuring 1 inch by 1 inch in cross-section, and an overall length of 6 inches. It supports groove widths from 0.185 inches to 0.25 inches and a maximum depth of cut of 1 inch, making it suited to precision grooving, parting, and cutoff work in production and job-shop environments.

This toolholder is intended for external grooving and cutoff applications in both production and job-shop turning operations. It is well-suited for use on standard CNC turning centers and conventional lathes where precise groove control is required. The GHGR 25.4-5 designation identifies the holder geometry, shank size, and insert family, allowing machinists and tool cribs to cross-reference quickly. It is installed by machinists and CNC operators working with ferrous and non-ferrous materials requiring clean, repeatable grooves or full parting cuts.

Installation Notes

Installation is performed by a machinist or CNC operator. Before mounting or changing inserts, ensure the machine spindle is fully stopped and the machine is in a safe, locked-out state per shop safety procedures. Seat the toolholder securely in the tool turret or tool post, verifying centerline height before operation. Use the correct torque wrench and clamp screw per the insert manufacturer's guidelines when securing the insert; do not overtighten by hand estimation alone.
