Scientific Cutting Tools AS5202-08S Porting Tool Carbide

Product Description

The SCIENTIFIC CUTTING TOOLS AS5202-08S is a carbide-tipped porting tool designed to machine O-ring face seal (ORFS) ports in metal workpieces to AS5202 and MS33649 standards. It produces a 1.2400-inch spotface diameter with a 30-degree seal angle and a 3/4-16 UNJF port thread size, creating the precise seating surface required for leak-free hydraulic and pneumatic tube fittings. The tool features a 3-flute straight flute geometry and a bright, uncoated finish. It is installed by machinists and hydraulic system fabricators working on tube assemblies requiring standardized port geometry.

This porting tool is intended for use on tube assemblies with a 1/2-inch outside diameter tube, corresponding to a Dash 8 tube designation. It is suited for fabrication and repair of hydraulic manifolds, plumbing blocks, and fluid power components where AS5202 or MS33649 compliant port faces are required. The plain pilot style is compatible with pre-drilled port locations, and the straight shank mounts directly in standard drill press or milling machine chucks for controlled spotfacing operations.

Key Features

• Carbide-tipped construction for extended tool life in ferrous and non-ferrous workpiece materials
• 1.2400-inch spotface diameter with 30-degree seal angle machined to AS5202 and MS33649 standards
• 3/4-16 UNJF port thread size for Dash 8 (1/2-inch OD) tube fitting compatibility
• 3-flute straight flute geometry for clean, consistent surface finish on the seal face
• Straight shank at 3/4-inch diameter for direct chuck mounting on standard machine tools
• Bright uncoated finish; no identification groove; standard series designation

Compatibility

Designed for use with 1/2-inch OD tube assemblies (Dash 8) requiring AS5202 and MS33649 compliant O-ring face seal port geometry with a 3/4-16 UNJF port thread size.

Installation Notes

This tool is installed and operated by machinists or hydraulic system fabricators using a drill press, milling machine, or similar rotating machine tool. Secure the straight shank firmly in the chuck and ensure the workpiece is clamped rigidly before beginning the spotfacing operation. De-energize and depressurize any hydraulic or pneumatic system fully before performing port machining or rework on installed components. Follow applicable fluid power system fabrication standards and shop safety procedures when operating cutting tools.
