The Hertel 1/8-27 NPT Thread Forming Pipe Tap is a precision threading tool designed for professional applications. Crafted from high-speed steel and enhanced with a TiN (Titanium Nitride) coating, this tap offers superior durability and extended tool life even under demanding conditions. With an overall length of 2-1/8 inches and a thread length of 3/4 inch, it provides excellent control during threading operations. The 7/16 inch shank diameter and 0.328 inch square size ensure compatibility with standard tap holders and wrenches. This thread forming tap creates threads by displacing material rather than cutting it, resulting in stronger threads with improved fatigue resistance. Ideal for plumbing applications and pipe fitting work, this Hertel tap delivers consistent, accurate threads in NPT (National Pipe Taper) configuration. The professional-grade construction makes it suitable for both industrial settings and skilled trades where precision threading is essential.
