Engineered to cut flawless American National Standard Taper Pipe Threads, the Guhring NPT Tapered Pipe Tap range delivers the extreme dimensional accuracy required for pressure-tight, leak-proof joints. Because NPT threading requires the tool to cut a continuous 1:16 taper along the entire engagement length, it creates high radial friction and massive chip loads. Guhring solves this mechanical challenge by manufacturing these premium pipe taps with optimized thread relief and specialized flute geometries that ensure smooth chip evacuation and zero binding. Ideal for high-pressure fluid systems, hydraulic blocks, and pneumatic manifold manufacturing, this industrial-grade range ensures maximum tool life and precise pitch compliance when tapping structural steels, cast iron, brass, and tough stainless steel components in manual or CNC applications. HSS APPLICATIONS Primary for hand tapping Great for cutting new threads & Cleaning existing threads Suited for use in a variety of ferrous and non-ferrous materials Green Ring for cutting - Structural steels - mild steel, 250 and 350 plate, Free cutting steels, Case hardened steels, Heat treatable steels, Nitriding steels, Spheroidal graphite cast iron HSS TECHNICAL DATA Made from High Speed Steel Standard - Guhring Std Surface - Bright Finish Thread angle - 60 Degree Guhring No. 973
