Accupro ACC-GF038-4 Full Radius Grooving Tool Solid Carbide

Product Description

The ACCUPRO ACC-GF038-4 is a solid carbide full radius grooving tool designed for precision internal grooving operations on CNC lathes and boring machines. Built from submicron-grade carbide, it delivers consistent cutting performance in small-bore applications where tool rigidity and edge retention are critical. The 5/16 inch shank diameter and 2.5 inch overall length make it well-suited for shallow internal groove work. A 0.0385 inch groove width and 0.110 inch projection allow controlled material removal in tight geometries. Machinists and toolroom operators working in production or job-shop environments will find this tool effective for grooving bores down to 0.312 inch minimum diameter.

This grooving tool is intended for use in metal cutting applications requiring a full radius groove profile in small internal diameters. It is appropriate for use in ferrous and non-ferrous materials where a smooth, consistent groove is required. The maximum hole depth of 0.250 inch (1/4 inch) makes it best suited for shallow grooving passes rather than deep-bore applications. Typical applications include O-ring groove preparation, snap ring groove cutting, and similar precision groove profiles in turned or bored components.

Key Features

• Submicron-grade solid carbide construction for superior hardness and edge retention
• Full radius cutting profile for smooth, consistent groove geometry
• 0.0385 inch groove width for fine, precision groove cuts
• 5/16 inch shank diameter for standard toolholder compatibility
• 0.110 inch projection supports access to small internal bore features
• Compact 2.5 inch overall length reduces overhang and improves rigidity

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for standard 5/16 inch bore grooving toolholders used in CNC turning and boring applications with minimum hole diameters of 0.312 inch.

Installation Notes

Installation and use of this grooving tool should be performed by a qualified machinist familiar with CNC lathe or boring machine operation. Ensure the machine spindle is fully stopped and the machine is locked out before changing or setting tooling. Verify shank clamping torque and projection length per the toolholder manufacturer specifications before beginning a cut. Do not exceed the maximum hole depth of 0.250 inch to avoid tool deflection or breakage.
