Scientific Cutting Tools AS5202-12RA Porting Tool Carbide

Product Description

The SCIENTIFIC CUTTING TOOLS AS5202-12RA is a carbide-tipped porting tool designed to machine O-ring face seal (ORFS) ports to AS5202 and MS33649 standards. It combines spotfacing and reaming in a single operation, producing a 1.6650-inch spotface diameter and a 1-1/16-12 UNJ threaded port geometry on 3/4-inch OD tubing. The 3-flute straight-flute design with an AlTiN coating delivers controlled material removal and extended tool life in ferrous and non-ferrous workpieces. Licensed machinists, hydraulic system fabricators, and fluid-power technicians install this tool wherever precision port geometry is required on tube assemblies.

This porting tool is built for tube assemblies with a Dash 12 tube designation, corresponding to 3/4-inch OD tubing. It machines the 30-degree seal angle and spotface face required for leak-free ORFS connections used in hydraulic lines, pneumatic systems, and fluid-power manifolds. The straight shank accepts standard milling machine, CNC machining center, or drill press setups. Applications are primarily industrial and aerospace tube-port machining where AS5202 and MS33649 port conformance is specified.

Key Features

• Machines AS5202 and MS33649 compliant O-ring face seal ports in a single pass
• Carbide-tipped construction with AlTiN coating for extended tool life and heat resistance
• 1.6650-inch spotface diameter with 30-degree seal angle for accurate ORFS geometry
• 3-flute straight-flute configuration for smooth, controlled cutting action
• Straight shank (3/4 inch diameter) for compatibility with standard toolholders
• Reamer pilot type ensures accurate alignment during spotface and port machining

Compatibility

Designed for use on tube assemblies conforming to AS5202 and MS33649 port standards, specifically Dash 12 tube size with 3/4-inch OD tubing and a 1-1/16-12 UNJ port thread size.

Installation Notes

This tool is intended for use by qualified machinists in machine shop or field-fabrication environments. Secure the straight shank firmly in an appropriate toolholder before operation and ensure the workpiece is rigidly fixtured. Always follow the machine manufacturer's recommended speeds and feeds for carbide-tipped tooling on the workpiece material. Inspect the pilot and cutting edges for wear before each use to maintain port geometry conformance.
