Accupro ACC-GR208-13 O-ring Grooving Tool 3/8 in

Product Description

The ACCUPRO ACC-GR208-13 is a solid carbide O-ring grooving tool designed for precision internal groove cutting in machining applications. Built from submicron-grade solid carbide, it delivers consistent groove geometry for O-ring seat profiles. The 3/8-inch shank diameter provides secure tool holding in standard collet chucks and holders. With a groove width of 0.2090 inches and a projection of 0.1250 inches, this tool is suited for machinists and tooling professionals who require repeatable, tight-tolerance results in bore grooving operations.

This grooving tool is used in precision machining environments where O-ring grooves must be cut to close tolerances. It is appropriate for use in CNC lathes and manual turning centers capable of accepting a 3/8-inch shank. The minimum hole diameter of 0.3750 inches and maximum hole depth of 13/16 inches define the bore range where this tool can be deployed. It is typically installed by machinists in job shops, maintenance machine shops, and production environments working with hydraulic, pneumatic, or fluid-sealing components that require O-ring grooves.

Key Features

• Submicron-grade solid carbide construction for wear resistance and edge retention
• O-ring grooving profile with 0.2090-inch groove width for accurate seat geometry
• 3/8-inch shank diameter compatible with standard collet and toolholder systems
• 0.1250-inch projection for controlled depth reach in bore applications
• Maximum hole depth of 13/16 inches supports a range of workpiece sizes
• Minimum bore entry of 0.3750 inches limits use to appropriately sized holes

Compatibility

Designed as a direct-fit grooving tool for CNC and manual lathes accepting a 3/8-inch shank, suitable for O-ring groove operations in bores with a minimum diameter of 0.3750 inches and a maximum depth of 13/16 inches.

Installation Notes

This tool is installed by machinists in a compatible toolholder or collet chuck rated for a 3/8-inch shank. Before mounting, verify that the spindle is fully stopped and the machine is locked out per standard shop safety procedures. Confirm bore diameter and depth specifications against the workpiece print before beginning the grooving pass. Do not exceed the rated maximum hole depth of 13/16 inches to avoid tool deflection or breakage.
