Scientific Cutting Tools MS33649-2S Porting Tool

Product Description

The SCIENTIFIC CUTTING TOOLS MS33649-2S is a porting tool engineered to spotface and prepare hydraulic or pneumatic tube port connections to AS 5202 and MS 33649 standards. It produces a 0.742-inch spotface diameter with a plain pilot and is designed for use with 1/8-inch outside diameter tubing (Tube Dash 2). The tool features a 3-flute straight-flute design, a 1/2-inch shank diameter, and a 3-inch overall length. It is used by aerospace, industrial, and mechanical trades to machine precise port faces that ensure leak-free tube fittings seated at a 30-degree seal angle with UNJF thread forms.

This porting tool is applied wherever tube port connections must conform to AS 5202 or MS 33649 standards. Typical scenarios include fabrication and MRO work on hydraulic manifolds, pneumatic assemblies, and fluid-system components that use 1/8-inch OD tubing. The tool is suited for CNC machining centers and manual mills where controlled spotfacing of port faces is required. It is used by aerospace mechanics, fluid-system fabricators, and precision machinists working on aluminum, steel, and other machinable workpiece materials.

Key Features

• 30-degree seal angle matches AS 5202 and MS 33649 port geometry requirements
• 3-flute straight-flute configuration for smooth, controlled cutting action
• 1/2-inch shank diameter and 2.000-inch shank length for standard toolholder compatibility
• Bright uncoated finish; 3.000-inch overall length with 1.000-inch head length

Compatibility

Designed for workpieces requiring AS 5202 and MS 33649 compliant tube port spotfacing with 1/8-inch OD tubing (Tube Dash 2) and UNJF thread forms.

Installation Notes

This tool is installed in a standard 1/2-inch toolholder on a milling machine or machining center. Ensure the spindle is fully stopped and the workpiece is securely fixtured before engaging the cutter. Follow shop-floor speeds and feeds appropriate for the workpiece material; consult the tool manufacturer or a machining reference for starting parameters. Verify port geometry against AS 5202 or MS 33649 drawing callouts after spotfacing to confirm conformance before assembly.
