Micro 100 QRR-046-20X Retaining Ring Grooving Tool

Product Description

The MICRO 100 QRR-046-20X is a solid carbide internal grooving tool designed for cutting retaining ring grooves in bored or drilled holes. The tool features a 3/8-inch shank diameter and a 0.046-inch groove width, making it suited for precision groove work in small-diameter bores. With an overall length of 2.5 inches and a 0.1-inch projection, it is built for controlled depth cutting in tight bore conditions. Machinists and toolmakers use solid carbide construction for its rigidity and wear resistance compared to high-speed steel alternatives, particularly in production environments where dimensional consistency matters.

This grooving tool is used in machining applications where internal retaining ring grooves must be cut to accept snap rings or circlips in bored features. It is suited for use in CNC lathes, manual lathes, and boring operations where the minimum hole diameter is 0.37 inches and the maximum hole depth does not exceed 1.25 inches. Typical applications include precision part manufacturing in industrial, aerospace, and mechanical assembly contexts where retaining ring grooves are required to secure components within a bore.

Key Features

• Solid carbide construction for rigidity, wear resistance, and dimensional consistency
• 0.046-inch groove width sized for standard retaining ring profiles
• 3/8-inch shank diameter for compatibility with common tool holders
• 0.1-inch projection allows controlled depth of cut in shallow-to-moderate bore depths
• Minimum bore entry diameter of 0.37 inches enables use in small-diameter holes
• Maximum hole depth of 1.25 inches covers a broad range of bore lengths

Compatibility

Designed for use in internal grooving operations on CNC and manual lathes accepting a 3/8-inch shank, with a minimum hole diameter of 0.37 inches and a maximum bore depth of 1.25 inches.

Installation Notes

This tool should be installed by a qualified machinist in a compatible tool holder that securely clamps a 3/8-inch shank. Ensure the workpiece is properly secured and the machine spindle is fully stopped before tool changes. Set projection and depth of cut according to the groove specification before commencing the cut. Verify bore diameter meets the 0.37-inch minimum before entry to avoid tool deflection or breakage.
