Accupro ACC-G187-20 Retaining Ring Grooving Tool

Product Description

The ACCUPRO ACC-G187-20 is a solid carbide retaining ring grooving tool designed for cutting internal retaining ring grooves in bored holes. Built from submicron-grade solid carbide, it delivers the edge retention and rigidity needed for precise groove geometry in production and maintenance machining operations. The tool features a 0.5 inch shank diameter and an overall length of 3 inches, making it compatible with standard toolholders used on CNC lathes and boring equipment. A 0.188 inch groove width and 0.16 inch projection allow accurate groove placement at depth. Machinists and toolroom technicians working in metalworking, repair, or OEM production environments are the primary users of this tool.

This grooving tool is suited for internal grooving applications where a retaining ring seat must be machined into a bored hole with a minimum diameter of 0.5 inches. It handles hole depths up to 1.25 inches, with a shank length of 2 inches providing reach and stability. Typical applications include machining retaining ring grooves in hydraulic cylinders, pump housings, gearbox bores, and similar precision components. It is intended for use by machinists and tool-and-die professionals in both job shop and production settings.

Installation Notes

This tool is installed by a qualified machinist. Secure the shank firmly in the toolholder to the full recommended engagement depth before operation. Ensure the workpiece is properly chucked and the machine spindle is at a complete stop before making any tool changes or adjustments. Follow machine manufacturer guidelines and applicable shop safety standards when selecting feeds, speeds, and coolant application for carbide grooving tools.
