Iscar 2800748 External Grooving Toolholder Phg Cut Grip

Product Description

The ISCAR 2800748 is an external right-hand indexable grooving toolholder designed for precision groove turning on CNC lathes and turning centers. Built to the PHG toolholder style in the Cut Grip series, it accepts GDMW 2.4 inserts secured by a mechanical clamp for reliable edge indexing without disturbing setup. The holder reaches a maximum depth of cut of 0.67 inches and handles groove widths from 0.094 inches up to 0.125 inches (1/8 inch). With an overall length of 4.5 inches and a square 0.75 x 0.75 inch shank, this toolholder suits a wide range of turning machine configurations. It is intended for installation and use by machinists and CNC operators working in production or job-shop environments.

This toolholder is classified for non-face grooving applications with a right-hand cutting direction. It is rated for universal primary workpiece material compatibility, covering material codes H, K, M, N, P, and S, which correspond to hardened materials, cast iron, stainless steel, non-ferrous metals, steel, and heat-resistant superalloys. A maximum workpiece diameter of 1.34 inches and a back-of-bar to cutting edge dimension of 0.71 inches define the usable work envelope. The 1.3 inch head length positions the insert precisely for consistent groove geometry across repeat operations.
