Micro 100 QRR-062-8X Retaining Ring Grooving Tool

Product Description

The MICRO 100 QRR-062-8X is a solid carbide face grooving tool designed for cutting internal retaining ring grooves in bored holes. With a 0.062-inch groove width and a 3/8-inch shank diameter, this tool is built for right-hand cutting operations on CNC lathes and manual turning centers. The solid carbide construction delivers the rigidity and wear resistance required for consistent groove geometry in precision machining applications. At 2.5 inches overall length with a 0.100-inch projection, it is suited for controlled depth grooving where dimensional accuracy is critical. Machinists and tool and die professionals rely on this style of grooving tool when fitting retaining ring grooves to exact tolerance.

The QRR-062-8X is intended for internal face grooving in bored holes with a minimum hole diameter of 0.370 inches and a maximum hole depth of 0.500 inches. It fits standard 3/8-inch shank toolholders common on small to mid-size lathes. Typical applications include precision component manufacturing, hydraulic cylinder work, and any turned part requiring an internal groove to seat a retaining or snap ring. This tool is used in job shops, production machining, and maintenance repair operations where tight groove tolerances are required.

Key Features

• Solid carbide construction for rigidity and extended tool life in grooving operations
• 0.062-inch groove width for retaining ring groove applications
• Right-hand cutting direction for standard lathe setups
• 0.100-inch projection supports controlled depth cuts to 0.500 inches maximum hole depth
• 3/8-inch shank diameter fits widely available toolholders
• 2.5-inch overall length provides clearance in typical small-bore applications

Compatibility

Designed for use in bored holes with a minimum diameter of 0.370 inches and a maximum depth of 0.500 inches. Fits standard 3/8-inch shank toolholders on CNC and manual lathes configured for right-hand internal face grooving.

Installation Notes

Installation and setup should be performed by a qualified machinist familiar with turning operations and toolholder torque procedures. Ensure the machine spindle is fully stopped and the lathe is locked out before mounting or removing the tool. Verify shank seating and tool projection before taking a cut, and confirm groove width and depth with a calibrated gauge before finishing to final dimension. Do not exceed the maximum hole depth specification of 0.500 inches.
