Description

  • ENGINEERED FOR NPS PARALLEL THREADS: Specifically designed for National Pipe Straight (NPS) internal tapping. Unlike tapered NPT taps, this tool creates consistent parallel threads ideal for mechanical joints, fuel rails, and hydraulic fittings requiring a precise, uniform fit
  • SPIRAL FLUTE CHIP EVACUATION: Features a high-helix spiral flute geometry that pulls chips upward and out of the hole. This design is critical for blind-hole tapping in "gummy" materials like aluminum and copper, preventing chip packing and catastrophic tool failure.
  • COBALT HSS DURABILITY: Formulated from Cobalt-fortified High-Speed Steel (HSS-E) to withstand extreme thermal loads. The cobalt content maintains edge hardness at higher RPMs, significantly extending tool life compared to standard carbon steel or basic HSS taps.
  • NON-FERROUS MATERIAL OPTIMIZATION: Precision-ground cutting edges excel in soft and abrasive materials including Cast Iron, Brass, Aluminum, and Steel (HRC<33). The geometry reduces torque requirements and prevents galling, ensuring a "mirror-finish" thread surface. Industrial tolerances for CNC setups, tapping machines, lathes, or mills internal pipe threads
