Accupro ACC-GS018F Cut-off Grooving Tool Bit 3/8 Inch Shank

Product Description

The ACCUPRO ACC-GS018F is a 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 hardness and edge retention required for precision grooving in steel, stainless, cast iron, and non-ferrous materials. The neutral cutting direction makes it suitable for straight-in plunge cuts. With a 0.018 inch minimum groove width and a maximum depth of cut of 0.060 inches, this bit is built for tight, accurate groove profiles in production and job shop environments. Machinists and CNC operators working with small-diameter grooves will find this tool bit sized and graded for consistent performance across repeated passes.

This tool bit is used in turning center and engine lathe applications where narrow groove profiles and controlled depth are required. It is well suited for grooving operations on workpieces where groove width tolerances are tight, such as snap ring grooves, undercuts, and parting operations on small-diameter stock. The 3/8 inch square shank fits standard tool holders sized for 3/8 inch shank tooling, making it compatible with a wide range of turret and quick-change tool post setups common in production machining environments.

Key Features

• Micrograin solid carbide tip for superior hardness and edge retention in grooving applications
• Neutral cutting direction supports straight plunge cuts without lateral cutting force bias
• Minimum groove width of 0.018 inches for precision narrow-groove work
• Maximum depth of cut of 0.060 inches suitable for snap ring grooves and undercuts
• Full radius tip geometry included for smooth groove floor profiles
• 3/8 inch square shank fits standard 3/8 inch tool holders without modification

Compatibility

Designed as a direct-fit replacement for GS-018F style single point grooving tool bits and compatible with standard tool holders and quick-change tool posts accepting a 3/8 inch square shank.

Installation Notes

Installation is performed by qualified machinists following standard lathe tooling setup procedures. Ensure the lathe spindle is fully stopped and the machine is powered down before inserting or removing the tool bit from its holder. Verify shank seating and set screw torque per the tool holder manufacturer guidelines before initiating a cut. Do not exceed the rated maximum depth of cut of 0.060 inches per pass to avoid tip fracture or premature tool failure.
