Micro 100 QFR-030-8X Full Radius Grooving Tool

Product Description

The MICRO 100 QFR-030-8X is a full radius grooving tool designed for internal grooving operations in precision machining applications. Constructed from solid carbide, it delivers the hardness and wear resistance required for consistent performance in ferrous and non-ferrous materials. The tool features a 0.030 inch groove width and a 0.25 inch shank diameter, making it well suited for small-bore grooving work where dimensional accuracy is critical. With an overall length of 3.0 inches and a projection of 0.050 inches, it is built for controlled reach in tight bore conditions. Machinists and tool-and-die professionals select this tool for applications demanding repeatable groove geometry.

The QFR-030-8X is intended for use in CNC lathes and manual turning centers where internal full radius grooving is required. It accommodates a minimum hole diameter of 0.245 inches and a maximum hole depth of 0.750 inches, making it appropriate for small-diameter bore work in production and job-shop environments. Typical applications include snap-ring grooves, O-ring grooves, and relief cuts in precision components across industries such as aerospace, hydraulics, and general machining.

Key Features

• Solid carbide construction for hardness and extended tool life in demanding materials
• Full radius profile delivers clean, consistent groove geometry in a single pass
• 0.030 inch groove width for tight-tolerance internal grooving
• Minimum hole diameter of 0.245 inches enables work in small-bore applications
• Maximum hole depth of 0.750 inches provides adequate reach for most internal groove locations
• 0.25 inch shank diameter for compatibility with standard toolholding systems

Compatibility

Designed as an OEM-style replacement and standard-fit grooving tool for use with toolholders accepting a 0.25 inch shank diameter on CNC and manual lathes configured for internal grooving operations.

Installation Notes

Installation should be performed by a qualified machinist familiar with turning center tooling setup. Secure the shank fully in the toolholder to the recommended engagement depth before operation to minimize deflection. Power down and lock out the machine before inserting or removing the tool. Verify bore clearance against the minimum hole diameter spec of 0.245 inches before use to avoid tool or workpiece damage.
