      Faster production
      Feeds are automatically changed from rapid approach to pitch feed to reverse feed on retract. This speed cycle greatly increases production capacity.
      Capable of class 3 thread accuracy
      Feed rate is synchronized with tool rotation allowing thin or soft materials to be worked efficiently.
      Flexibility to meet your specifications
      Easy adjustment for tap diameter, thread pitch and stroke length.
      Compact, versatile set-up
      Compact size allows installation in small spaces and operation at any angle.
      Long stroke, a variety of attachments
      Simple changeover from single tap head to mum-tap heads allows flexibility lot- use In either small lot or large lot production runs.
