Scientific Cutting Tools GT038-8 Retaining Ring Grooving Tool

Product Description

The SCIENTIFIC CUTTING TOOLS GT038-8 is a solid carbide internal grooving tool designed for cutting retaining ring grooves in bored holes. Built from submicron-grade solid carbide, it delivers the hardness and edge retention needed for precision grooving in ferrous and non-ferrous materials. The tool has a 5/16 inch shank diameter and an overall length of 2.5 inches, making it suitable for compact CNC lathe setups and manual boring operations. With a groove width of 0.0385 inches, it is suited for light, accurate retaining ring seat cuts. Machinists and tool-and-die professionals install this tool in standard collet or end mill holders.

This grooving tool is used in internal boring applications where a retaining ring groove must be cut at a controlled depth and width. It is appropriate for small-bore work with a minimum hole diameter of 0.312 inches and a maximum hole depth of 0.5 inches. The right-hand cutting direction suits standard lathe spindle rotation. It fits production machining, job shop, and maintenance-and-repair operations where precision groove geometry is required.

Key Features

• Solid submicron-grade carbide construction for superior wear resistance and edge retention
• 0.0385 inch groove width for precise retaining ring seat geometry
• Minimum bore entry of 0.312 inches suits small internal diameter work
• Maximum hole depth of 0.5 inches with a 0.11 inch projection from shank centerline
• 5/16 inch shank diameter fits standard collet chucks and tool holders
• Right-hand cutting direction for use with standard spindle rotation

Compatibility

Designed as an OEM-style replacement or direct-use internal grooving tool for small-bore retaining ring applications in CNC lathes and manual boring equipment that accept a 5/16 inch round shank toolholder.

Installation Notes

Installation is performed by qualified machinists following standard toolroom practices. Ensure the machine spindle is fully stopped and locked out before mounting or removing the tool. Seat the shank fully in the collet or holder and torque the clamping fasteners per the holder manufacturer specification. Verify bore entry clearance against the 0.312 inch minimum hole diameter before beginning the cut to avoid tool or workpiece damage.
