Scientific Cutting Tools AND10050-4S Porting Tool Tube Dash 4

Product Description

The SCIENTIFIC CUTTING TOOLS AND10050-4S is a porting tool designed to spotface and prepare tube port seats in hydraulic and pneumatic fittings applications. Built to AND 10050 standards, it features a 0.888-inch spotface diameter and a plain pilot configuration with 4 straight flutes for clean, controlled cutting. The tool accepts a 1/4-inch tube outside diameter (Tube Dash 4) and runs on a 1/2-inch shank. At 3.12 inches overall length and weighing 0.25 pounds, it is compact enough for bench or machine use. Machinists and maintenance technicians in aerospace, fluid power, and industrial settings rely on this tool to produce accurate, flat port surfaces that meet tight dimensional requirements.

This porting tool is suited for spotfacing tube port workpieces where a flat, clean seating surface is required for tube fittings. The 30-degree seal angle and UNF thread type make it appropriate for standard aerospace and fluid-system port preparation. It is intended for use on tube workpieces requiring a Tube Dash 4 configuration and is manufactured to AND 10050 dimensional standards. The bright finish provides a hard, smooth cutting surface for consistent performance across repeated operations.

Key Features

• Spotface diameter of 0.888 inches for precise port seat preparation
• Plain pilot type with minimum pilot diameter of 0.385 inches and maximum of 0.4565 inches
• 4 straight flutes for smooth, consistent material removal
• 30-degree seal angle compatible with standard tube port fitting geometry
• 1/2-inch shank diameter with 2.0-inch shank length for secure machine or hand-tool holding
• Bright coating finish for smooth cutting action and surface quality

Compatibility

Designed for use with 1/4-inch OD tube workpieces (Tube Dash 4) and manufactured to AND 10050 standards for aerospace and fluid-power port porting applications.

Installation Notes

This tool is typically operated by machinists or maintenance technicians using a drill press, milling machine, or appropriate hand-held driver. Secure the workpiece firmly before operation and ensure the pilot engages the existing port bore squarely to prevent misalignment. Consult applicable aerospace or fluid-system maintenance standards for required surface finish and dimensional tolerances on the spotfaced seat. Always de-energize and depressurize any hydraulic or pneumatic system before performing port rework.
