Iscar 2801592 Indexable Grooving Toolholder Sumo Grip

Product Description

The ISCAR 2801592 is an external right hand indexable grooving toolholder designed for precision grooving operations on CNC lathes and turning centers. Built to the TGBH style, this toolholder features a 1 inch by 1 inch steel shank with an overall length of 5.9 inches and a maximum depth of cut of 0.98 inches. The groove width is fixed at 0.315 inches. Through-coolant capability directs cutting fluid directly to the cutting zone, supporting higher cutting speeds and longer insert life. It is part of the ISCAR Sumo Grip series and conforms to ISO 13399 standards. Licensed machinists and CNC operators install this holder in production turning environments where consistent groove geometry and secure insert clamping are required.

This toolholder is suited for external grooving applications across a universal range of workpiece materials, including steel, stainless, cast iron, non-ferrous alloys, and superalloys, as indicated by material codes H, K, M, N, P, and S. The clamp-style insert holding method provides rigid support during interrupted cuts and high-feed grooving passes. It is a non-face grooving style holder intended for standard OD grooving on bar stock, shafts, and turned components in both job shop and production environments.

Installation Notes

Installation should be performed by a qualified machinist with the machine powered down and the spindle locked before mounting or removing the toolholder.
