Allied Machine J1926-080-075F Indexable Porting Tool 3/4-16

Product Description

The ALLIED MACHINE AND ENGINEERING J1926-080-075F is an indexable porting tool designed for machining SAE straight-thread O-ring port faces and sealing surfaces in hydraulic and fluid power components. Built to the AccuPort 432 series, it accepts two porting inserts and machines to a 3/4-16 port thread size with a pilot diameter of 0.688 inches and a spotface diameter of 1.207 inches. The tool covers a porting diameter of 0.813 inches and features a 15-degree seal angle, making it suited for precision port preparation where both the spotface and seal angle must be cut in a single operation. It weighs 0.6 pounds and measures 3.951 inches in overall length.

This tool is used in manufacturing, maintenance, and repair environments where SAE J1926-1/MS-16142 and ISO 11926-1 straight-thread port standards apply. Typical applications include hydraulic manifold machining, cylinder head porting, and fluid power assembly work across a wide range of base materials. The universal primary workpiece material rating covers steel, cast iron, non-ferrous metals, and plastics, indicated by material codes H, K, N, and P. It is installed by machinists and tool and die professionals working on hydraulic or pneumatic systems requiring precise port geometry.

Compatible with J1926 series indexable inserts, specifically insert styles J1926-07-C3H and J1926-07-C5A (size codes 450H-0022 and 4C10H-0022). Conforms to port standards ISO 11926-1 and SAE J1926-1/MS-16142. Tube Dash Number 8 porting applications.

Installation Notes

This tool is installed and operated by machinists on milling machines, machining centers, or drill presses equipped with the appropriate shank interface. Power down and lock out the machine spindle before changing inserts or adjusting the tool. Verify port standard requirements against the workpiece drawing before selecting insert geometry. Follow the machine tool manufacturer torque and runout specifications for tool holding to maintain porting accuracy.
