Iscar 2500448 External Grooving Toolholder Heli-grip

Product Description

The ISCAR 2500448 is an external right-hand indexable grooving toolholder designed for precision grooving operations on CNC lathes and turning centers. Built on the Heli-Grip platform, it accepts DG.-5 and GRIP-5 series inserts secured by a clamp-style holding method. The toolholder delivers a maximum depth of cut of 0.47 inches with a groove width of 0.197 inches. The overall length is 6 inches, with a square shank measuring 1 inch by 1 inch. This toolholder is intended for use by machinists and CNC operators working with a universal range of workpiece materials across production and job-shop environments.

The 2500448 is suited for external non-face grooving applications in both production and general-purpose turning. Its right-hand cutting direction makes it compatible with standard spindle rotation on most CNC turning centers. The toolholder is rated for universal primary workpiece material compatibility, covering material groups H, K, M, N, P, and S per ISO 13399 classification, making it applicable across steel, stainless, cast iron, non-ferrous, and heat-resistant alloys. Machinists running medium to high-volume grooving operations will find the Heli-Grip clamping system provides consistent insert indexing and repeatable tool position.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Power down and lock out the machine before mounting or changing toolholders. Ensure the shank bore and toolholder mating surfaces are clean and free of chips before clamping. Follow the machine tool manufacturer torque specifications for tool clamping hardware, and verify tool overhang and runout before resuming cutting operations.
