Large Diameters

The ROBUST tap style has a special crown-shaped front portion of this tool provides excellent accuracy even in the first stage of the cutting process. Extra clean and accurate threads can be cut in this way. The cutting chips are collected in the hollow face of the tap (internal chip collector) when cutting blind hole threads. For this tool, we recommend using paste lubrication wherever possible. Oil lubrication is possible only in vertical machining, if the blind hole can be completely filled with oil.


  • Premium HSSE substrate material
  • Hollow face for chip collection space
  • Form C chamfer length (2-3 threads)
  • For blind hole and through hole threads
