Scientific Cutting Tools AS5202-16R Porting Tool Reamer

Product Description

The SCIENTIFIC CUTTING TOOLS AS5202-16R is a carbide-tipped porting tool designed for spotfacing and reaming O-ring face seal (ORFS) ports in hydraulic and pneumatic tubing assemblies. It machines a 1.9650-inch spotface diameter on 1-inch OD tubing to the AS5202 and MS33649 standards, producing a clean, flat seating surface for leak-free port connections. The tool features a straight 3-flute geometry with a bright, uncoated finish and is built to handle the precision demands of aerospace, industrial, and fluid power fabrication work. Licensed machinists, hydraulic system fabricators, and fluid power technicians are the primary users.

This tool is suited for applications requiring accurate port preparation on tube dash 16 fittings with a 1-5/16-12 UNJ thread port. It is used in the fabrication and repair of hydraulic lines, pneumatic systems, and related fluid power assemblies where AS5202 and MS33649 port standards are specified. The straight shank allows use in standard milling machines, drill presses, and CNC machining centers. Workpiece compatibility is limited to tubes as noted in the product specifications.

Key Features

• 1.9650-inch spotface diameter machined to AS5202 and MS33649 standards
• 3-flute straight flute design for clean material removal and accurate seating surfaces
• 30-degree seal angle conforms to ORFS port geometry requirements
• Straight shank with 1-inch shank diameter for broad machine compatibility
• Bright, uncoated finish - no coating buildup to affect critical dimensional tolerances

Compatibility

Designed for port preparation on tube dash 16 assemblies with 1-inch OD tubing and 1-5/16-12 UNJ port threads, conforming to AS5202 and MS33649 standards.

Installation Notes

Installation and operation of this porting tool should be performed by qualified machinists or fluid power technicians familiar with ORFS port preparation procedures. Secure the workpiece firmly before operation and ensure the spindle speed is appropriate for carbide tooling on the workpiece material. Always power down and lock out the machine before changing tools or inspecting the cutting edges. Follow applicable shop safety standards and fluid system fabrication specifications throughout the porting process.
