Accupro ACC-G039-6 Retaining Ring Grooving Tool

Product Description

The ACCUPRO ACC-G039-6 is a solid carbide retaining ring grooving tool designed for internal groove cutting in precision machining applications. Built from submicron carbide grade material, it delivers consistent edge sharpness and wear resistance across high-volume or tight-tolerance operations. The tool features a 3/8-inch shank diameter and a 0.0400-inch groove width, making it well suited for cutting narrow retaining ring grooves in bored holes. Machinists and tool and die professionals install this type of tool in CNC lathes or boring operations where exact groove geometry is required for snap ring or retaining ring seating.

This grooving tool is used in internal bore applications requiring a minimum hole diameter of 0.3750 inches and a maximum hole depth of 0.3750 inches. The 0.1100-inch projection and 2-1/2-inch overall length provide the reach and rigidity needed for accurate groove placement in small-diameter bores. It is appropriate for ferrous and non-ferrous workpiece materials where a solid carbide cutting edge is preferred over inserted or brazed alternatives.

Key Features

• Solid submicron carbide construction for improved wear resistance and edge retention
• 0.0400-inch groove width for precise retaining ring groove cutting
• 3/8-inch shank diameter for standard collet or tool holder compatibility
• 0.1100-inch projection suited for small internal bore applications
• 2-1/2-inch overall length provides reach with minimal overhang flex
• Minimum hole diameter of 0.3750 inches supports compact bore geometries

Compatibility

Designed as an OEM-style replacement or direct-use internal grooving tool for CNC lathes and boring setups requiring a 3/8-inch shank retaining ring grooving cutter.

Installation Notes

This tool is installed by machinists and tool and die professionals into compatible tool holders or collet chucks accepting a 3/8-inch shank. Ensure the machine spindle is fully stopped and the tool holder is properly torqued before beginning any cut. Verify workpiece bore diameter meets the 0.3750-inch minimum before engagement to avoid tool deflection or breakage. Follow shop-standard speeds and feeds for solid carbide internal grooving tools based on workpiece material.
