Micro 100 QMFR-030-375-080 Full Radius Grooving Tool

Product Description

The MICRO 100 QMFR-030-375-080 is a full radius grooving tool machined from solid carbide for use in internal grooving operations on small-bore workpieces. It carries a 0.0300 inch groove width and a 3/16 inch shank diameter, making it suited for precision grooving in tight bores starting at 0.0800 inches in diameter. The full radius profile produces a clean, consistent groove geometry in a single pass. Machinists and toolroom operators use this tool on CNC lathes and boring equipment where dimensional accuracy and surface finish in small internal features are critical.

This tool is intended for internal grooving applications in small-diameter bores on production or prototype parts. With a maximum hole depth of 0.6000 inches and a projection of 0.0250 inches, it is suited for shallow groove work in materials where carbide tooling provides the necessary wear resistance and edge retention. Typical applications include snap ring grooves, oil retention grooves, and relief cuts in precision-machined components across aerospace, medical device, and general machining environments.

Key Features

• Solid carbide construction for superior hardness and edge retention in demanding materials
• Full radius grooving profile for consistent groove geometry in a single pass
• 0.0300 inch groove width for fine, precise internal groove features
• Minimum bore entry diameter of 0.0800 inches enables work in very small holes
• Maximum hole depth of 0.6000 inches with 0.0250 inch projection
• 3/16 inch shank diameter for standard collet and toolholder compatibility

Compatibility

Designed as a direct-fit internal grooving tool for use with standard 3/16 inch bore toolholders and collet chucks on CNC lathes and manual turning equipment.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the shank firmly in a compatible collet or toolholder to the specified runout tolerance of the machine before engaging the workpiece. Ensure the machine spindle is fully stopped and the machine is in a safe, locked-out state before installing or removing the tool. Do not exceed the stated maximum hole depth to avoid tool deflection or breakage.
