Micro 100 RRC3-038-750-312 Retaining Ring Grooving Tool

Product Description

The MICRO 100 RRC3-038-750-312 is a solid carbide internal grooving tool designed for cutting retaining ring grooves in bored holes. It features a 5/16 inch shank diameter and a 0.038 inch groove width, making it well suited for precision groove work in small-diameter bores. With an overall length of 2.5 inches and a 0.1 inch projection, the tool provides controlled reach into the workpiece. Machinists and toolroom technicians install this tool in CNC lathes, manual lathes, or boring setups where a dedicated retaining ring groove profile is required.

This grooving tool is intended for internal retaining ring groove applications in bores with a minimum hole diameter of 0.3125 inches. It accommodates a maximum hole depth of 0.75 inches, making it suitable for shallow-bore grooves in precision components. Typical applications include machining snap ring grooves in hydraulic cylinders, actuators, housings, and mechanical assemblies across industrial and manufacturing environments. The solid carbide construction supports use in ferrous and non-ferrous materials where edge retention and dimensional accuracy are priorities.

Key Features

• Solid carbide construction for extended tool life and dimensional stability
• 0.038 inch groove width for standard retaining ring profiles
• Minimum bore entry of 0.3125 inches suits small-diameter internal grooves
• Maximum hole depth of 0.75 inches for shallow-bore retaining ring applications
• 0.1 inch projection provides controlled cutting reach
• 5/16 inch shank diameter for compatibility with standard toolholders

Compatibility

Designed as an OEM-style grooving tool for use in standard 5/16 inch bore-type toolholders on CNC and manual lathes configured for internal retaining ring groove operations.

Installation Notes

This tool should be installed by a qualified machinist or toolroom technician familiar with lathe tooling setup. Ensure the machine is fully stopped and de-energized before securing or changing tooling. Use a properly sized toolholder that matches the 5/16 inch shank diameter and verify projection length before engaging the cut. Do not exceed the maximum hole depth rating of 0.75 inches to avoid tool deflection or breakage.
