Iscar 2800917 Internal Grooving Toolholder 0.5 in Shank

Product Description

The ISCAR 2800917 is a right-hand internal indexable grooving toolholder from the ChamGroove series, designed for precision internal grooving operations on CNC turning centers and lathes. It accepts GIQR/L 8 series inserts secured by screw clamping and supports a maximum depth of cut of 0.059 inches with groove widths ranging from 0.02 inches to 0.118 inches. The toolholder features through-coolant capability to manage chip evacuation and heat at the cutting zone. With an overall length of 3.62 inches and a 0.5-inch round shank, this MG-style holder is a compact, application-specific tool intended for licensed machinists and CNC tooling specialists working in precision turning environments.

This toolholder is suited for internal non-face grooving in bores with a minimum hole diameter of 0.315 inches. The right-hand cutting direction makes it appropriate for standard spindle rotation turning setups. It is rated for universal primary workpiece materials, covering ISO material groups H, K, M, N, P, and S, which span hardened steels, cast irons, stainless steels, non-ferrous alloys, general steels, and superalloys. The through-coolant feature is particularly useful in deep-bore grooving where flood coolant cannot reach the insert tip effectively. This toolholder is a fit for job shops and production turning operations requiring consistent, repeatable internal groove geometry.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and all power is locked out before inserting or changing the toolholder or inserts. Confirm bore clearance meets the minimum hole diameter requirement of 0.315 inches before mounting. Verify through-coolant supply line compatibility with the machine tool before use.
