North American Tool Thread Mills

North American Tool is now making Thread Mills.

Do you have a three axis (or more) CNC machine? Is that machine modern enough to have a circular interpolation program already installed? Can you manually install a program to run thread mills? If you can say yes, you can use thread mills to some significant advantages over traditional tapping applications.

North American Thread mills help you and your shop in a variety of ways:

  • Exceptional quality threads on a variety of materials including specific styles for exotic materials and aluminum.
  • Depending on the work in your shop, fewer thread mills may be required to produce threads than the number of taps needed for the same jobs (no need for taper, plug and bottom forms).
  • Tap breakage (caught in piece part hole) is virtually eliminated.
  • Less horsepower is required for similar jobs, smaller chips, less stress on tool.
  • Thread mills are particularly well-suited for thin walled work pieces versus taps.
  • Multiple H Limits can be achieved with the same tool based on programming expertise.
  • Cut RH and LH threads with the same tool.
  • Thread blind holes to the bottom.
  • Eliminates the need for expensive taps and tapping chucks.
  • Helical form disperses the chip load more efficiently to allow for a smoother cut and finish on piece part.
  • When the length of the tapped hole exceeds the ideal recommendations from engineering, thread mills can reach deeper without similar consequences.
  • Taps may be used up to 45 RC with few issues. 45 RC to 50 RC may require special geometry to accommodate. Carbide thread mills will handle material up to 60 RC and could be modified to tackle up to 65 RC.
