Accupro ACC-GR086F Grooving Tool Bit 3/8x3/4 Inch Carbide

Product Description

The ACCUPRO ACC-GR086F is a right-hand, single-point cut-off and grooving tool bit designed for precision groove turning operations on CNC lathes and manual turning centers. Built with a micrograin solid carbide tip brazed to a rigid steel shank, this tool bit delivers tight groove tolerances with a minimum groove width of 0.086 inches and a maximum groove width of 0.088 inches. Maximum depth of cut reaches 0.27 inches, making it suited for moderate-depth grooving passes. The GR style geometry is optimized for grooving and parting applications. Machinists and tool-and-die professionals install this bit into standard boring bars or tool holders sized for a 3/8 inch shank width and 3/4 inch shank height.

This tool bit is used in production and job-shop turning environments where consistent groove width control is required. It performs well on ferrous and non-ferrous materials where micrograin carbide grade provides the wear resistance needed for repeat groove passes. The right-hand cutting direction suits standard lathe setups running conventional feed direction. Typical applications include external grooving, snap-ring groove cutting, and facing relief cuts on turned components. It is packaged and sold individually.

Compatibility

Designed for use in tool holders and boring bars accepting a 3/8 inch shank width and 3/4 inch shank height. Conforms to industry standard number GR-086F.

Installation Notes

Installation is performed by qualified machinists following standard lathe tooling setup procedures. Ensure the lathe spindle is fully stopped and the machine is in a safe locked-out state before seating or adjusting the tool bit in the holder. Secure the shank firmly in the tool post or holder to the manufacturer-specified clamping method to prevent chatter. Inspect the carbide tip for chipping or wear before each use, as a damaged tip can affect groove width accuracy and surface finish.
