Accupro 40680001 External Grooving Toolholder 0.75 in

Product Description

The ACCUPRO 40680001 is a right-hand external grooving toolholder designed for indexable insert grooving operations on CNC lathes and turning centers. Built to GMER toolholder style specifications, it accepts all GD24 series inserts with a 2.0 mm groove width and uses a screw-clamping insert holding method for secure, repeatable positioning. The steel construction provides rigidity during interrupted cuts and high-feed grooving passes. With a maximum depth of cut of 23.00 mm and a 0.75-inch square shank, this holder suits a wide range of external grooving and part-off setups in both production and job-shop environments.

This toolholder is intended for external grooving applications on conventional and CNC turning equipment. It is installed by machinists and toolroom technicians working on lathes with standard tool post or turret tooling stations that accommodate a 0.75-inch shank. The right-hand cutting direction and neutral-compatible insert hand make it adaptable for standard OD grooving profiles. The CI series designation places it within a family of indexable grooving tooling commonly used in general-purpose turning operations.
