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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInternal right-hand cutting orientation for bore grooving operations\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design directs fluid to the cutting edge for improved chip control and tool life\u003c\/li\u003e\n  \u003cli\u003eScrew-clamp insert holding method provides secure, repeatable insert seating\u003c\/li\u003e\n  \u003cli\u003eCompatible with a broad range of GIQR\/L insert geometries for flexible groove sizing\u003c\/li\u003e\n  \u003cli\u003eMinimum hole diameter of 0.315 inches enables use in small-bore applications\u003c\/li\u003e\n  \u003cli\u003eConforms to ISO 13399 tool data standards for seamless CAM integration\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible insert size codes include GIQR\/L 8, GIQR\/L 8-R, GIQR\/L 11, GIQR\/L 11-R, GIQR\/L 11-15, GIQR\/L 11-15-R, GIQR\/L-A18, GIQR\/L-B18, GIQR\/L-MT, and GIQR\/L-WT.
