Meet the Tanoi NPT Tap Bright Straight Flute HSS-E V3—a precision threading tap designed to create accurate 1/16 x 27 NPT threads across a wide range of materials. Built for durability in demanding environments, it delivers clean, consistent threads with every cut.

  • Thread size and type: 1/16" x 27 NPT threading for standard pipe fittings
  • Material: HSS-E (high-speed steel with enhanced cobalt content) for superior hardness and heat resistance
  • Flute design: Straight flute geometry for efficient chip evacuation and reduced cutting forces
  • Finish: Bright finish that supports visibility and general wear resistance
  • Applications: Specifically designed for pipe threading with NPT fittings across a broad range of materials
  • Material compatibility: Suitable for a variety of metals and common workpieces encountered in plumbing, hydraulic, and pneumatic systems

This tap is engineered to help you achieve reliable, tight NPT connections without excessive tool wear or runout. The straight flute design minimizes chip buildup and heat, while the cobalt-enhanced HSS-E core ensures longevity even in tougher cutting conditions. Whether you’re assembling small-diameter piping, performing repairs, or tackling fieldwork, this tap provides a dependable solution for precise internal threads that seal effectively with standard NPT fittings.
