NPT and Pipe Taps
NPT (National Pipe Thread) or pipe tap drill bits are specialized tools designed for creating threaded connections in pipes and fittings. They feature a tapered design that gradually increases in diameter, allowing for a tight seal as the tap is screwed into a pre-drilled hole, which is crucial for preventing leaks. The threads on NPT taps are typically at a 60-degree angle, conforming to standard pipe threading for compatibility with other NPT fittings. Commonly used in plumbing, HVAC, and gas applications, these taps are made from high-speed steel (HSS) or other durable materials for cutting through tough materials like steel and brass. Available in various sizes, NPT pipe tap drill bits are essential for ensuring secure, leak-proof connections in a variety of piping systems.
