Iscar 2800920 Internal Grooving Toolholder 0.059in Chamgroove

Product Description

The ISCAR 2800920 is an internal right-hand indexable grooving toolholder from the ChamGroove series, designed for precision internal grooving operations on CNC lathes and turning centers. It accepts GIQR/L 8 series inserts secured by a screw-clamp holding method, delivering positive insert location and repeatable cutting performance. The toolholder handles groove widths from 0.02 inches to 0.118 inches with a maximum depth of cut of 0.059 inches. Through-coolant capability directs cutting fluid directly to the cutting zone, extending insert life and improving chip evacuation in deep or tight-bore applications. It carries an overall length of 3.62 inches with a 0.5-inch shank diameter and is built to ISO 13399 standards for tool data representation.

The 2800920 is suited for internal non-face grooving in small-bore workpieces, with a minimum hole diameter of 0.315 inches. The MG-style toolholder profile is compatible with universal workpiece materials across ISO classifications including P, M, K, N, S, and H. Typical applications include snap ring groove machining, undercut profiling, and internal recessing on precision turned components in production or job-shop environments. Licensed machinists and CNC programmers working in metalcutting operations are the primary users of this toolholder style.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before changing the toolholder or indexing inserts. Verify through-coolant passages are clear and properly connected to the machine turret supply before operation. Confirm insert size code compatibility and torque the insert clamping screw according to ISCAR insert documentation before cutting.
