Accupro ACC-GS038002 Cut-off Grooving Tool Bit 3/8 in

Product Description

The ACCUPRO ACC-GS038002 is a GS-style single point tool bit designed for cut-off and grooving operations on metal lathes and turning centers. It features a micrograin solid carbide tip brazed to a square shank measuring 3/8 inches wide by 3/8 inches tall. The neutral cutting direction makes it suitable for straight plunge grooving without left or right offset. Groove width capability ranges from 0.038 inches minimum to 0.040 inches maximum, with a maximum depth of cut of 0.12 inches. A minimum nose radius of 0.002 inches supports tight-tolerance groove profiles. Machinists and toolroom operators select this bit for precision parting and grooving on small-diameter workpieces.

This tool bit is intended for use in production and toolroom environments where consistent, repeatable groove geometry is required. It fits standard square-shank tool holders with a 3/8 inch bore. Typical applications include narrow groove cutting, parting operations, and undercut work on ferrous and non-ferrous materials. The micrograin carbide grade provides fine edge retention at elevated cutting speeds, making it appropriate for both CNC turning centers and manual engine lathes.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the shank firmly in the tool holder and verify the cutting tip is on center with the workpiece spindle axis before engaging the cut. Power down the machine and lock out the spindle before changing or inspecting the tool bit. Avoid side loading the tip beyond the rated groove width, as micrograin carbide is brittle and subject to edge chipping under lateral force.
