Description

The Tanoi NPT Tap Bright Straight Flute HSS-E V3 is a purpose-built pipe-threading tap designed for professionals who install and service NPT fittings. Crafted with a cobalt-enhanced HSS-E core, it delivers reliable, clean threads across a broad range of materials in demanding environments.

  • Thread size: 1/8"-27 NPT pipe thread for standard, compatible fittings
  • Material: HSS-E (high-speed steel with enhanced cobalt content) for improved wear resistance and heat tolerance
  • Flute design: Bright, straight flute geometry to promote smooth chip evacuation and lower cutting forces
  • Finish: Bright finish for visibility and corrosion resistance in tough workshop and field conditions
  • Versatility: Suitable for threading a wide range of materials with NPT compatibility across common pipe projects
  • Version: V3 design optimized for durability in repeated-use environments

This tap is engineered to produce precise, sealable NPT threads with minimal torque, reducing chatter and giving you dependable outcomes on every job. The straight-flute approach handles chip evacuation efficiently, which helps maintain smooth cutting action even as threads deepen. The V3 variant combines the toughness of HSS-E with a refined geometry to stand up to busy shop floors and field service, making it a reliable choice for plumbing, hydraulic, and pneumatic applications that demand durable, long-lasting taps.
