SAEJ1926 Port Tools Ideal for Non-Standard Thread Minor Diameters and Lengths

The SAEJ1926-X series is a brand-new style of port tools by Scientific Cutting Tools that meet the SAEJ1926/1 and MS16142 port specifications. This tool offering is ideal for non-standard thread minor diameters and lengths.

The tools have three flutes, are coolant through, and do not have a pilot diameter. This series is also designed to replace SCT’s line of piloted port tools. Historically, solid pilot tools were used to line up the tool to the hole when using manual milling or drilling equipment. With the widespread use of modern CNC equipment, the solid pilot is no longer necessary, and sometimes detrimental.

The SAEJ1926-X will cut the required spot face and O-Ring taper only; it does not cut the thread minor diameter. A coolant hole to each flute aids with increased chip evacuation, higher speeds and feeds, and longer tool life. The polished flute face optimizes performance for a smoother surface finish. The body of the port tool is made of heat-treated alloy steel and the brazed inserts are made of premium quality sub-micron carbide.

Tools are in stock and available to order either uncoated or AlTiN+ coated. For ferrous and hard-to-machine materials, the coated version is highly recommended.

  • computer numerical control ( CNC)

    computer numerical control ( CNC)

    Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.

  • coolant


    Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.

  • flutes


    Grooves and spaces in the body of a tool that permit chip removal from, and cutting-fluid application to, the point of cut.

  • gang cutting ( milling)

    gang cutting ( milling)

    Machining with several cutters mounted on a single arbor, generally for simultaneous cutting.

  • milling


    Machining operation in which metal or other material is removed by applying power to a rotating cutter. In vertical milling, the cutting tool is mounted vertically on the spindle. In horizontal milling, the cutting tool is mounted horizontally, either directly on the spindle or on an arbor. Horizontal milling is further broken down into conventional milling, where the cutter rotates opposite the direction of feed, or “up” into the workpiece; and climb milling, where the cutter rotates in the direction of feed, or “down” into the workpiece. Milling operations include plane or surface milling, endmilling, facemilling, angle milling, form milling and profiling.
