Iscar 2500452 Indexable Grooving Toolholder Heli-grip

Product Description

The ISCAR 2500452 is an external, right-hand indexable grooving toolholder in the Heli-Grip series, designed for turning and grooving operations on CNC lathes and turning centers. It accepts DG.-4 and GRIP-4 insert styles, secured by a clamp-style holding method for rigid, repeatable positioning. The shank measures 1 inch by 1 inch with a shank length of 4.35 inches and an overall length of 6 inches. Maximum workpiece diameter is 1.97 inches. Groove width range runs from 0.157 inches to 0.187 inches. This toolholder is installed by machinists and CNC operators working in job shop or production environments.

The 2500452 is suited for external grooving applications across a broad range of workpiece materials, including steel, cast iron, stainless steel, non-ferrous alloys, and high-temperature alloys, corresponding to ISO material groups P, M, K, N, H, and S. The Heli-Grip series is a common choice on CNC turning centers where consistent groove geometry and secure insert retention are priorities. With a back-of-bar to cutting edge dimension of 0.94 inches and a head length of 1.65 inches, the holder provides adequate clearance for most standard external grooving setups.
