Accupro ACC-GR120F Cut-off Grooving Tool Bit Solid Carbide Rh

Product Description

The ACCUPRO ACC-GR120F is a right-hand, single point tool bit designed for cut-off and grooving operations on CNC and manual lathes. It features a micrograin solid carbide tip brazed to a steel shank, delivering the edge retention and surface finish quality that production machinists demand. The shank measures 0.375 inches wide by 0.75 inches tall, fitting standard toolpost and boring bar setups. Maximum depth of cut is 0.4 inches, with a groove width range of 0.120 to 0.122 inches, making it well suited for tight-tolerance grooving passes where dimensional consistency is critical.

This tool bit is intended for use in turning centers and engine lathes where external grooving, necking, or parting operations are performed on steel, cast iron, stainless, and non-ferrous materials. The GR style geometry is optimized for grooving applications requiring a full-radius cutting profile, which helps control chip flow and reduces lateral cutting forces during plunge cuts. It is a direct fit for standard tool holders accepting a 0.375 inch by 0.75 inch shank profile and is sold individually.

Key Features

• Micrograin solid carbide tip for superior wear resistance and edge sharpness on hard materials
• Full-radius cutting geometry reduces lateral load during grooving plunge cuts
• Groove width range of 0.120 to 0.122 inches suits precision necking and snap-ring groove applications
• Maximum depth of cut of 0.4 inches covers most standard external grooving requirements
• Right-hand cutting direction for conventional lathe setups
• Industry standard number GR-120F for cross-reference and replacement sourcing

Compatibility

Designed as an OEM-style replacement or direct substitution for any toolpost or holder accepting a 0.375 inch wide by 0.75 inch tall single point tool bit shank in GR style grooving applications. Industry standard number GR-120F applies for cross-reference purposes.

Installation Notes

Installation is performed by a machinist or toolroom technician. Power down and lock out the spindle before seating or removing any tool bit. Ensure the shank is fully seated and clamped to the correct overhang specification for the holder being used to minimize chatter and deflection. Follow the machine tool manufacturer guidelines for tool height alignment relative to the workpiece centerline before initiating any cut.
