Scientific Cutting Tools MS33649-10S Porting Tool Dash 10

Product Description

The SCIENTIFIC CUTTING TOOLS MS33649-10S is a porting tool designed to machine precision spotfaces and pilot holes for MS 33649 and AS 5202 port fittings on hydraulic, pneumatic, and fluid system tubing assemblies. The tool produces a 1.415-inch spotface diameter on 5/8-inch OD tubing with a 30-degree seal angle, meeting the dimensional requirements of UNJF threaded boss ports. Four straight flutes and a bright, uncoated finish support controlled chip evacuation during the spotfacing operation. This tool is used by aerospace and industrial maintenance technicians, fluid power specialists, and precision machinists working to AS 5202 and MS 33649 standards.

This porting tool is suited for spotfacing tube boss ports in hydraulic and pneumatic systems where MS 33649 or AS 5202 fitting standards apply. The plain pilot type engages the existing hole for concentricity during the cut. Typical applications include fabrication and repair of fluid line assemblies on tube dash number 10 connections. The 3/4-inch shank diameter is compatible with standard milling machine and drill press chucks used in shop or depot-level maintenance environments.

Key Features

• 1.415-inch spotface diameter machined to MS 33649 and AS 5202 port standards
• 30-degree seal angle for proper boss port sealing geometry
• Plain pilot type with 0.809-inch minimum and 0.899-inch maximum pilot diameter for concentric engagement
• Four straight flutes for efficient chip removal during spotfacing
• 3/4-inch shank diameter fits standard machine toolholders
• Bright, uncoated finish - no coating thickness to account for in critical dimensions

Compatibility

Designed for use on 5/8-inch OD tubing at tube dash number 10, conforming to AS 5202 and MS 33649 port fitting standards with UNJF thread type boss ports.

Installation Notes

This tool is intended for use by machinists and fluid system technicians in controlled shop or maintenance environments. Secure the workpiece and ensure the machine spindle is fully stopped before mounting or removing the tool. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain surface finish quality. Verify spotface depth and diameter with calibrated gauges after machining to confirm conformance to the applicable AS 5202 or MS 33649 dimensional requirements.
