Accupro ACC-G087-8 Retaining Ring Grooving Tool

Product Description

The ACCUPRO ACC-G087-8 is a solid carbide retaining ring grooving tool designed for internal grooving operations on bores. Built from submicron-grade solid carbide, it delivers the hardness and edge retention needed for precise groove cutting in demanding materials. The tool features a 3/8 inch shank diameter and cuts a groove width of 0.0880 inches, making it well-suited for machining retaining ring grooves in small-diameter bores. With an overall length of 2.5 inches and a shank length of 2.0 inches, it fits standard toolholders used on CNC lathes and manual turning centers. Machinists and tool-and-die tradespeople rely on this type of solid carbide grooving tool for consistent, repeatable groove geometry in production and maintenance applications.

This grooving tool is intended for internal retaining ring groove applications where bore access and groove precision are critical. It is rated for a minimum hole diameter of 0.3750 inches and a maximum hole depth of 0.5000 inches, making it appropriate for small-bore work on components such as hydraulic cylinders, pump housings, valve bodies, and similar machined parts. It suits both job-shop and production environments where retaining ring grooves must conform to tight dimensional tolerances.

Key Features

• Submicron-grade solid carbide construction for extended tool life and edge sharpness
• 0.0880 inch groove width sized for retaining ring groove profiles
• Minimum bore entry of 0.3750 inches allows use in small-diameter holes
• Maximum hole depth of 0.5000 inches covers typical retaining ring groove locations
• 3/8 inch shank diameter compatible with standard collet and toolholder systems
• 2.5 inch overall length provides reach while maintaining rigidity

Compatibility

Designed as an OEM-style grooving tool for use in CNC and manual turning applications requiring internal retaining ring grooves in bores with a minimum diameter of 0.3750 inches.

Installation Notes

This tool is installed by machinists in a lathe toolholder or collet chuck sized for a 3/8 inch shank. Ensure the machine spindle is fully stopped and the tool is securely clamped before beginning any setup or tool change. Confirm bore diameter and depth clearances against the 0.3750 inch minimum hole diameter and 0.5000 inch maximum depth ratings before commencing the cut. Proper cutting fluid application is standard practice for solid carbide grooving tools to manage heat and chip evacuation.
