Scientific Cutting Tools MS33514-10CT Porting Tool

Product Description

The SCIENTIFIC CUTTING TOOLS MS33514-10CT is a porting tool designed for spotfacing and porting operations on tube fittings conforming to AS 33514 and MS 33514 standards. It features a 0.83-inch spotface diameter and a plain pilot with a minimum pilot diameter of 0.498 inches and a pilot length of 0.740 inches. The tool has 3 straight flutes, a straight shank, and a bright finish with no identification groove. With an overall length of 3.15 inches and a shank length of 1.88 inches, it is built for use in aerospace, hydraulic, and fluid-system fabrication environments where precise tube port preparation is required.

This porting tool is compatible with 5/8-inch outside diameter tubes and is designated for Tube Dash 10 applications. It is used when preparing tube port seats to the MS 33514 and AS 33514 standards, which govern UNJF-threaded fittings with a 12-degree seal angle. It is typically used by aerospace mechanics, hydraulic technicians, and fluid-system assemblers working on high-tolerance tube connections in aerospace, defense, and industrial applications requiring consistent, repeatable spotface geometry.

Key Features

• Plain pilot type with 0.498-inch minimum pilot diameter
• 3 straight flutes for clean material removal
• 12-degree seal angle and UNJF thread type per AS 33514 and MS 33514 standards
• Straight shank with 1.88-inch shank length for secure tool holding
• Bright finish with no identification groove

Compatibility

Designed for use with 5/8-inch OD tubes at Tube Dash 10 designation, conforming to AS 33514 and MS 33514 standards for UNJF-threaded tube port fittings.

Installation Notes

This tool is installed in a compatible straight-shank tool holder and operated by machinists or hydraulic technicians on a drill press or CNC platform. Ensure the workpiece tube is securely fixtured and the pilot is properly aligned before engaging the cutter to avoid spotface runout. Always power down and de-energize any associated fluid system before performing port preparation work on installed assemblies. Follow applicable aerospace or industrial standards for surface finish and dimensional inspection after spotfacing.
