Accupro ACC-RC312100 Single Point Tool Bit Cut-off Grooving

Product Description

The ACCUPRO ACC-RC312100 is a single point tool bit designed for cut-off and grooving operations on manual and CNC lathes. Built with a solid carbide tip brazed to a steel shank, it delivers consistent edge retention and heat resistance through interrupted cuts and continuous grooving passes. The shank measures 5/16 inches wide by 5/16 inches tall, and the overall length is 6 inches. The tip is 0.100 inches thick and 0.100 inches wide, giving machinists a precise, narrow cutting profile suited for parting stock and cutting shallow grooves. This is a right-hand cutting bit, intended for machinists and toolroom technicians working in production or job-shop environments.

The ACC-RC312100 is used in turning applications where a narrow, rigid tool bit is required to part off finished workpieces or machine grooves in cylindrical stock. The RC-style geometry is well-suited for use in standard tool holders that accept 5/16-inch shank tooling. Typical applications include parting steel, aluminum, and similar machinable materials on engine lathes and turret lathes. This tool bit is sold individually and is a direct match to industry standard number RC-312100.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Before changing tool bits, power down the lathe and bring the spindle to a complete stop. Secure the tool bit firmly in the holder to the correct centerline height before taking any cuts. Inspect the carbide tip for chipping or damage before each use, as a damaged tip can cause workpiece deflection or tool breakage.
