Accupro ACC-GR090F Cut-off Grooving Tool Bit Lh Carbide

Product Description

The ACCUPRO ACC-GR090F is a left-hand single point tool bit designed for cut-off and grooving operations on the lathe. It features a micrograin solid carbide tip brazed to a steel shank, delivering the edge retention and wear resistance needed for consistent groove geometry in ferrous and non-ferrous materials. The shank measures 3/8 inch wide by 3/4 inch tall, fitting standard tool holders in that size range. Maximum groove width is 0.092 inch and maximum depth of cut is 0.300 inch. This tool bit is used by machinists and toolroom technicians in production and job-shop environments where tight groove tolerances are required.

The ACC-GR090F suits turning centers and engine lathes equipped with standard tool post holders accepting a 3/8 x 3/4 inch shank. Its left-hand cutting direction makes it appropriate for operations where the tool feeds right to left or for setups that require opposite-hand geometry. The GR style and full-radius tip geometry allow clean groove entry and consistent sidewall finish. Typical applications include O-ring groove cutting, parting-adjacent grooving, and precision channel work in small-diameter workpieces.

Compatibility

Designed as a direct-fit replacement for industry standard GR-090F style single point grooving tool bits. Fits standard tool post holders and boring bars accepting a 3/8 inch wide by 3/4 inch tall shank.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Secure the tool bit firmly in the tool holder with set screws torqued per the tool holder manufacturer specifications before engaging the workpiece. Ensure the cutting edge is set at the correct center height for the lathe prior to operation. Inspect the carbide tip for chipping or wear before each use and replace if edge condition is compromised.
