Accupro ACC-G055-16 Retaining Ring Grooving Tool

Product Description

The ACCUPRO ACC-G055-16 is a solid carbide internal grooving tool designed for cutting retaining ring grooves in bored holes. Built from submicron-grade carbide, it delivers consistent performance in precision machining applications where groove geometry and tool life are critical. The tool features a 3/8-inch shank diameter and cuts a groove width of 0.0560 inches. With an overall length of 2.5 inches and a shank length of 1.2 inches, it is sized for use in CNC lathes and manual turning centers. Machinists and toolroom technicians use this style of grooving tool when internal retaining ring grooves must be held to close tolerances.

This grooving tool is suited for internal retaining ring groove operations in small-bore workpieces. The minimum hole diameter it will enter is 0.3750 inches, and it can reach a maximum hole depth of 1.0 inch. The 0.1100-inch projection supports controlled depth engagement during the grooving pass. It is appropriate for ferrous and non-ferrous materials in job shop, production, and toolroom environments where solid carbide tooling is the standard choice for consistency and repeatability.

Key Features

• Submicron-grade solid carbide construction for wear resistance and edge retention
• 0.0560-inch groove width sized for standard internal retaining ring profiles
• 3/8-inch shank diameter for compatibility with common toolholders and collet chucks
• 0.1100-inch projection enables controlled depth engagement
• Minimum hole entry diameter of 0.3750 inches suits small-bore applications
• Maximum hole depth of 1.0 inch covers typical retaining ring groove reach requirements

Compatibility

Designed as an OEM-style replacement and standard-use internal grooving tool for CNC and manual turning applications requiring a 3/8-inch shank and 0.0560-inch groove width.

Installation Notes

This tool is installed and serviced by machinists and toolroom technicians on CNC or manual lathes. Secure the shank firmly in a compatible toolholder or collet chuck before operation and verify runout before engaging the workpiece. Ensure the machine spindle is fully stopped and locked out before changing or adjusting the tool. Do not exceed the stated maximum hole depth or projection engagement to avoid tool deflection or breakage.
