Internal Tool 24-1615 Retaining Ring Grooving Tool

Product Description

The INTERNAL TOOL 24-1615 is a solid carbide interior retaining ring grooving tool designed for cutting internal grooves in bored holes. Built from micrograin solid carbide, it delivers precise groove geometry in a single pass. The tool features a left-hand cutting direction, a minimum hole diameter of 0.375 inches, and a groove width of 0.095 inches. With an overall length of 2.5 inches and a 3/8-inch shank diameter, it fits standard toolholders used on lathes and boring setups. Machinists and tool-and-die professionals use this tool when installing internal retaining rings in precision bored components.

This grooving tool is suited for interior retaining ring groove applications in production and job-shop environments. It is configured for left-hand cutting, making it appropriate for specific spindle rotation and setup requirements. The full-radius tip geometry produces a clean groove profile matched to standard retaining ring cross-sections. Maximum hole depth capacity is 0.75 inches, with a projection of 0.75 inches and a shank length of 1.75 inches. It is intended for use in CNC lathes, manual lathes, and boring mills where internal groove work is performed on close-tolerance parts.

Key Features

• Micrograin solid carbide construction for wear resistance and edge retention in hard materials
• Left-hand cutting direction for dedicated left-hand spindle or reverse-rotation setups
• Full radius tip geometry sized for retaining ring groove profiles
• Minimum bore entry of 0.375 inches with a maximum hole depth of 0.75 inches
• Groove width of 0.095 inches for precise ring-seat dimensioning
• No undercut and no adjusting screw - fixed geometry for repeatable results

Compatibility

Designed as an OEM-style replacement or direct-use interior retaining ring grooving tool for lathes and boring mills accepting a 3/8-inch shank toolholder.

Installation Notes

This tool is installed and operated by machinists on lathes or boring mills. Confirm spindle rotation matches the left-hand cutting direction before engaging the workpiece. Secure the shank fully in the toolholder to the recommended engagement depth before taking a cut. Always bring the machine to a full stop before measuring groove dimensions or changing tooling.
