Accupro ACC-GF039-8 Full Radius Grooving Tool

Product Description

The ACCUPRO ACC-GF039-8 is a solid carbide full radius grooving tool designed for internal grooving operations on CNC lathes and turning centers. Built from submicron-grade solid carbide, it delivers precise groove geometry in a compact profile suited for tight-bore applications. The tool features a 3/8 inch shank diameter, a 0.0400 inch groove width, and an overall length of 2.5 inches. Machinists and tool-and-die professionals rely on this type of tool for consistent, repeatable groove profiles in a single pass without secondary finishing operations.

This grooving tool is suited for internal grooving in bores with a minimum hole diameter of 0.3750 inches and a maximum hole depth of 0.5000 inches. It is commonly used in precision machining environments including job shops, production turning cells, and toolroom applications where tight tolerances and clean groove profiles are required. The submicron carbide grade provides the wear resistance needed for machining ferrous and non-ferrous materials at typical turning speeds.

Key Features

• Full radius grooving profile for consistent groove geometry in a single pass
• Submicron-grade solid carbide construction for extended tool life and wear resistance
• 3/8 inch shank diameter compatible with standard boring bar holders and collet chucks
• 0.0400 inch groove width for narrow internal groove applications
• 0.1100 inch projection supports controlled depth reach within the bore
• 2.0 inch shank length provides secure clamping engagement

Compatibility

Designed for use in standard 3/8 inch boring bar holders and collet-style tool holders used on CNC lathes and manual turning centers. Suitable for bores with a minimum diameter of 0.3750 inches and a maximum depth of 0.5000 inches.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the shank fully within the tool holder to the recommended clamping length before cutting. Ensure the machine spindle is at a full stop and all axes are at a safe home position before changing or indexing any tooling. Follow the machine manufacturer guidelines and applicable shop safety procedures when setting tool offsets and running first-article cuts.
