Accupro ACC-GS028002 Cut-off Grooving Tool Bit 3/8 Inch

Product Description

The ACCUPRO ACC-GS028002 is a single point cut-off and grooving tool bit designed for precision grooving operations on CNC lathes and manual turning centers. Built with a micrograin solid carbide tip, this neutral-cutting GS-style bit delivers tight dimensional control in grooving applications where groove width consistency is critical. The 3/8-inch shank width and 3/8-inch shank height provide a rigid, stable platform that minimizes chatter during interrupted cuts. With a maximum groove width of 0.030 inches and a maximum depth of cut of 0.090 inches, this tool bit is suited for fine, precise grooves in a range of workpiece materials.

This tool bit is used in production and job-shop turning environments where cut-off and grooving operations are performed on metals and hard materials. The neutral cutting direction makes it appropriate for straight plunge grooving applications. It is typically installed by machinists and CNC operators on toolholders that accept standard GS-style single point inserts or brazed tool bits. It fits well in both high-volume production runs and precision single-part work where groove geometry must stay within tight tolerances.

Key Features

• Micrograin solid carbide tip for extended tool life and edge sharpness in grooving applications
• Neutral cutting direction suits straight plunge grooving without left or right bias
• GS tool bit style with 3/8-inch square shank for rigid, low-vibration setup
• Maximum groove width of 0.030 inches and minimum groove width of 0.028 inches for precise, repeatable cuts
• Maximum depth of cut of 0.090 inches supports shallow-to-mid-depth grooving work
• Minimum nose radius of 0.002 inches allows tight corner geometry at the groove base

Compatibility

Designed as an OEM-style single point tool bit for use in standard GS-style toolholders accepting 3/8-inch shank cut-off and grooving tool bits on CNC and manual turning equipment.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Power down and lock out the machine before seating or removing the tool bit from the holder. Ensure the shank is fully seated and clamped square to the holder centerline before resuming cuts. Inspect the carbide tip for chipping or wear before each use, as micrograin carbide tips are brittle under impact and should not be used on interrupted cuts outside the tool's rated depth of cut.
