Accupro ACC-GR122002 Cut-off Grooving Tool Bit

Product Description

The ACCUPRO ACC-GR122002 is a single-point, cut-off and grooving tool bit designed for precision grooving operations on CNC lathes and manual turning centers. Built from solid micrograin carbide, it delivers a minimum groove width of 0.122 inches and a maximum groove width of 0.124 inches, with a maximum depth of cut of 0.4 inches. The GR-style bit mounts in a 3/8 x 3/4 inch shank profile and cuts in the right-hand direction. Machinists and tool-and-die professionals use this bit for parting, grooving, and undercut work where tight dimensional tolerances are required.

This tool bit is suited for grooving applications on ferrous and non-ferrous materials where a tight groove width tolerance is critical. The micrograin carbide grade provides wear resistance and edge retention at higher surface speeds. The GR-122002 industry standard designation makes it a direct reference for shops sourcing replacements or specifying tooling by standard number. Typical applications include O-ring groove cutting, snap-ring groove machining, and parting-off operations on bar stock in production turning environments.

Key Features

• Solid micrograin carbide construction for extended edge life and dimensional stability
• Groove width range of 0.122 to 0.124 inches for tight tolerance grooving
• Maximum depth of cut of 0.4 inches suits most parting and grooving applications
• Right-hand cutting direction; GR tool bit style for standard GR-type holders
• Minimum nose radius of 0.002 inches with a radius range of 0.002 to 0.005 inches
• 3/8 x 3/4 inch shank fits common GR-style toolholders without modification

Compatibility

Designed for use in GR-style single-point toolholders accepting a 3/8 x 3/4 inch shank. References industry standard number GR-122002 for direct cross-referencing with equivalent tooling specifications.

Installation Notes

Installation is performed by a machinist or tool crib technician. Secure the shank firmly in the toolholder to the manufacturer-specified clamping requirements before engaging the workpiece. Ensure the cutting edge height is set on center for the workpiece diameter being machined. Inspect the carbide tip for chipping or wear before each use, as micro-chipping on solid carbide can cause premature groove width deviation.
