Accupro ACC-G039-8 Retaining Ring Grooving Tool

Product Description

The ACCUPRO ACC-G039-8 is a solid carbide retaining ring grooving tool designed for internal groove cutting operations on bored holes. Built from submicron-grade solid carbide, it delivers consistent groove geometry in hardened and abrasive materials where high-speed steel tooling falls short. The shank diameter is 3/8 inches, overall length is 2-1/2 inches, and the shank length measures 2.0 inches. A groove width of 0.0400 inches makes it suited to precision retaining ring seats. Machinists and toolroom technicians working with CNC lathes or boring setups rely on this tool for tight-tolerance internal grooving applications.

This tool is used in machining environments where internal retaining ring grooves are required in bored holes with a minimum hole diameter of 0.3750 inches. It accommodates a maximum hole depth of 0.5000 inches (1/2 inch) and features a projection of 0.1100 inches. Typical applications include production machining, toolroom work, and repair operations where retaining ring seats must be cut to exact width and depth. It is appropriate for use in both manual and CNC lathe setups handling small-bore internal grooving.

Key Features

• Submicron-grade solid carbide construction for extended tool life in abrasive and hardened materials
• Groove width of 0.0400 inches for precision retaining ring seat cutting
• 3/8 inch shank diameter compatible with standard toolholders
• Projection of 0.1100 inches allows controlled depth reach into the bore
• Maximum hole depth capacity of 0.5000 inches suits common small-bore retaining ring applications
• Compact overall length of 2-1/2 inches reduces overhang and improves rigidity

Compatibility

Designed as an OEM-style retaining ring grooving tool for use in standard 3/8 inch bore toolholders on CNC and manual lathes requiring internal groove cutting with a minimum bore entry diameter of 0.3750 inches.

Installation Notes

This tool is installed by qualified machinists in a lathe or CNC turning center toolholder with a matching 3/8 inch bore. Ensure the machine spindle is fully stopped and the toolholder is securely locked before inserting or removing the tool. Verify runout and projection before beginning a grooving pass to avoid chipping the carbide edge. Follow the machine manufacturer guidelines and applicable shop safety procedures when setting up internal grooving operations.
