Port contour cutters for SAE J1926 straight thread O-ring ports.
Port Tools for Straight-Thread O-Ring Boss Ports
Specification-led port tools for SAE J1926 straight-thread O-ring boss ports — engineered around the required port geometry, pre-hole, sealing surface, workpiece material, machine, and production objective.
Use the configuration that matches the controlled port form, pre-hole condition, machine capability, material, and production objective.
A solid pilot guides the cutter from a controlled pre-hole. Use this approach only after the pre-hole diameter, depth, and positional condition are confirmed.
A cutting pilot can finish the minor-diameter region while the form section produces the required entry and spotface geometry.
Pilotless configurations may suit selected CNC setups where the toolpath, machine rigidity, pre-hole, and chip-control strategy are controlled.
Coolant delivery, cutting material, coating, flute geometry, reach, and shank can be evaluated against the actual part and process.
SAE J1926/1 defines straight-thread O-ring boss port geometry used in hydraulic and fluid-power systems. The finished port depends on the relationship among the thread minor diameter, entry form, sealing area, and spotface. Confirm the port size, drawing revision, and mating connection before tool selection.
Provide the governing standard and revision, dash or thread size, controlled port drawing, required minor diameter and spotface features, pre-hole size and depth, workpiece material and hardness, machine and holder, coolant method, inspection plan, and annual volume. State whether the tool must finish the minor diameter.

Whole-form review. The pilot, minor diameter, chamfer, sealing area, and spotface are reviewed as one port geometry rather than isolated features.
Pilot strategy matched to the process. Solid-pilot, reamer-pilot, or pilotless construction is selected only after the pre-hole and machine conditions are understood.
Application-specific tool design. Cutting material, coating, flute form, coolant delivery, length, and shank are evaluated for the confirmed material and production target.
Send the component drawing, port callout, pre-hole condition, material, machine setup, and current process. JIAYI will review the complete form and prepare a standard or custom-tool proposal after technical confirmation.
