Micro 100 QFR-030-4 Full Radius Grooving Tool

Product Description

The MICRO 100 QFR-030-4 is a solid carbide full radius grooving tool designed for cutting retaining ring grooves in bored holes. Built for right-hand cutting, it produces a 0.030-inch wide groove with a full radius profile, making it well-suited for precision internal groove work on CNC lathes and machining centers. The tool features a 3/8-inch shank diameter and an overall length of 2.5 inches, with a projection of 0.100 inches. Solid carbide construction provides the rigidity and wear resistance required for consistent groove geometry in production and job-shop environments.

This tool is used for machining internal retaining ring grooves in bored features with a minimum hole diameter of 0.397 inches and a maximum hole depth of 0.750 inches. It is suited for right-hand turning operations in ferrous and non-ferrous materials where a full radius groove form is required. Typical applications include hydraulic cylinder bodies, bearing housings, and other precision-bored components that require internal snap ring or retaining ring seats.

Key Features

• Solid carbide construction for high rigidity and extended tool life
• Full radius groove profile for retaining ring seat applications
• 0.030-inch groove width with 0.100-inch projection
• Right-hand cutting direction for standard lathe and turning center setup
• Minimum hole diameter of 0.397 inches supports small-bore grooving
• Maximum hole depth of 0.750 inches for through and blind bore applications

Compatibility

Designed as an OEM-style replacement or direct-use internal grooving tool for right-hand turning operations requiring a full radius retaining ring groove profile in bored features.

Installation Notes

This tool is installed by machinists and toolroom technicians on CNC lathes or turning centers. Ensure the tool holder and shank bore are clean and properly torqued before running. Confirm the spindle is fully stopped and the machine is in a safe state before changing tooling. Do not exceed the rated maximum hole depth of 0.750 inches during grooving operations.
