Scientific Cutting Tools SAEJ1926-04RA Porting Reamer Dash 4

Product Description

The SCIENTIFIC CUTTING TOOLS SAEJ1926-04RA is a straight-flute porting reamer designed to finish-machine port seats in hydraulic and fluid-system fittings to SAE J1926, SAE J514, and MS 16142 standards. Built for Tube Dash 4 applications, it features a 3-flute straight-flute geometry with an AlTiN+ coating for extended tool life in hardened and stainless materials. The minimum pilot diameter is 0.388 inches and the maximum pilot diameter is 0.4865 inches, with a pilot length of 0.457 inches. Overall length is 3.12 inches and the shank diameter is 1/2 inch. Machinists and hydraulic system fabricators use this tool to generate accurate port geometries that accept SAE straight-thread O-ring fittings.

This reamer is used in the production and repair of hydraulic manifolds, fluid power components, and plumbing assemblies requiring SAE J1926 straight-thread O-ring ports or SAE J514 tube fitting ports. It is suited for both shop-floor machining operations and field repair scenarios where proper port geometry must be restored or established before fitting installation. The 12-degree seal angle and UNF thread type are consistent with standard SAE straight-thread port requirements.

Key Features

• Compliant with SAE J1926, SAE J514, and MS 16142 port standards
• 3-flute straight-flute design for controlled material removal and clean port finish
• AlTiN+ coating for extended tool life in ferrous and hardened alloy materials
• 12-degree seal angle matches SAE straight-thread O-ring port geometry
• 1/2-inch shank diameter for compatibility with standard tool holders and drill chucks
• Pilot diameter range of 0.388 to 0.4865 inches ensures accurate pilot engagement

Compatibility

Designed for machining Tube Dash 4 port seats per SAE J1926, SAE J514, and MS 16142 standards in hydraulic and fluid power components requiring UNF straight-thread O-ring port configurations.

Installation Notes

This tool is intended for use by machinists and hydraulic system technicians operating lathes, milling machines, or hand-held drilling equipment. Secure the 1/2-inch shank firmly in the tool holder before operation and ensure the workpiece is properly fixtured to prevent movement. Always de-energize and depressurize any hydraulic system completely before performing port rework or repair. Follow the machine tool manufacturer and applicable industry guidelines for cutting speeds, feeds, and lubrication when using coated reamers on hardened materials.
