MILLHOG Dictator Welding End Prep Tool

January 01, 2014

An upgraded welding end prep tool for machining high temperature, high pressure pipe used on severe-duty offshore piping systems and shale pumping stations is being introduced by ESCO Tool.

The MILLHOG Dictator Welding End Prep Tool is an I.D. clamping pipe milling machine designed for dry-cutting high-temperature, high-pressure pipe from 4.5" I.D. to 18" O.D. Ideally suited for stainless steel and super duplex piping systems, this tool features a new 3 HP air motor designed for high performance in environments that have dirty air and high moisture content.

Easy to clean and maintain the air motor by just removing one screw to access the rotor & vane assembly, instead of removing the motor from the tool, the MILLHOG Dictator Welding End Prep Tool develops 4,100 ft.-lbs. of torque at the cutter blade and pulls a continuous thick chip without cutting oils. Blades are TiN coated and dissipate heat away from the pipe's surface.

The MILLHOG Dictator Welding End Prep Tool is priced from $21,995.00 and is available for rent from $850.00 per week, depending upon location.

Related Glossary Terms

  • gang cutting ( milling)

    gang cutting ( milling)

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

  • milling

    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.

  • milling machine ( mill)

    milling machine ( mill)

    Runs endmills and arbor-mounted milling cutters. Features include a head with a spindle that drives the cutters; a column, knee and table that provide motion in the three Cartesian axes; and a base that supports the components and houses the cutting-fluid pump and reservoir. The work is mounted on the table and fed into the rotating cutter or endmill to accomplish the milling steps; vertical milling machines also feed endmills into the work by means of a spindle-mounted quill. Models range from small manual machines to big bed-type and duplex mills. All take one of three basic forms: vertical, horizontal or convertible horizontal/vertical. Vertical machines may be knee-type (the table is mounted on a knee that can be elevated) or bed-type (the table is securely supported and only moves horizontally). In general, horizontal machines are bigger and more powerful, while vertical machines are lighter but more versatile and easier to set up and operate.

  • titanium nitride ( TiN)

    titanium nitride ( TiN)

    Added to titanium-carbide tooling to permit machining of hard metals at high speeds. Also used as a tool coating. See coated tools.
