Accupro ACC-GR080002 Cut-off Grooving Tool Bit 3/8 in

Product Description

The ACCUPRO ACC-GR080002 is a single point cut-off and grooving tool bit designed for precision grooving operations on CNC and manual lathes. It features a micrograin solid carbide tip brazed to a steel shank, delivering consistent edge retention and dimensional accuracy in interrupted and continuous cuts. The shank measures 0.375 inches wide by 0.75 inches tall, and the tool is ground for right-hand cutting direction. Groove width ranges from 0.080 to 0.082 inches with a maximum depth of cut of 0.270 inches, making it well suited for narrow, precise groove profiles in ferrous and non-ferrous materials.

This tool bit is intended for use in production and job-shop turning environments where tight groove tolerances are required. Typical applications include external grooving, parting operations, and cut-off work on bar stock, shaft components, and turned parts. It is installed by machinists, tool-and-die makers, and CNC lathe operators working in both light and medium-duty turning setups. The GR style geometry and micrograin carbide grade support stable cutting action in materials that demand sharp, wear-resistant tooling.

Installation Notes

This tool bit is installed by qualified machinists or CNC lathe operators. Before changing or seating the tool bit, power down the machine and verify the spindle has come to a complete stop. Secure the shank firmly in the toolholder using the appropriate clamping hardware to eliminate overhang and chatter. Inspect the carbide tip for chipping or wear before each use and do not run a damaged insert.
