Internal Tool 20-1480 O-ring Grooving Tool Solid Carbide

Product Description

The INTERNAL TOOL 20-1480 is a solid carbide interior O-ring grooving tool designed for cutting precision O-ring grooves inside bored holes. Built from micrograin solid carbide, it delivers consistent groove geometry in a right-hand cutting direction. The tool accepts a minimum hole diameter of 0.375 inches and cuts a groove width of 0.0480 inches. With a 3/8-inch shank diameter and an overall length of 2.5 inches, it is sized for use in CNC lathes and manual turning centers where tight tolerances and repeatable groove profiles are required. Machinists and tool and die professionals are the primary users of this tooling.

This grooving tool is suited for interior O-ring groove applications in hydraulic components, pneumatic fittings, valve bodies, and precision machined housings where sealing grooves must meet tight dimensional tolerances. The 1.0-inch maximum hole depth and 1.0-inch projection allow access into shallow bores. The 1.5-inch shank length provides secure clamping in standard tool holders. No undercut geometry and no tool bit adjusting screw keep the design straightforward for production or maintenance shop environments.

Key Features

Compatibility

Designed as an OEM-style replacement and standard fit for interior O-ring grooving operations in turning centers and CNC lathes accepting a 3/8-inch shank tool holder.

Installation Notes

Installation and use of this grooving tool should be performed by a qualified machinist or tooling professional. Ensure the machine spindle is fully stopped and the tool holder is securely locked before seating or removing the tool. Verify shank clamping length meets the tool holder manufacturer minimum engagement requirements before running. Follow applicable shop safety standards for carbide tooling, including proper chip management and eye protection.
