Cleveland C56705 Pipe Tap 1/2"-14 NPT

This Cleveland C56705 pipe tap cuts internal NPT threads in a 1/2"-14 size. The semi-bottoming design with four flutes suits through-hole and blind-hole work in pipe and conduit fittings. It is made from high-speed steel with a TiN coating for wear resistance. Professional plumbers and maintenance technicians use it for new installations or repair threading.

Check thread size and drill before ordering

Verify that the workpiece requires a 1/2"-14 NPT thread and that the tap drill matches the 75 percent thread drill size of .7031 in. The tap has an overall length of 3 1/8 in and a thread length of 1 3/8 in, so confirm the hole depth accommodates this reach. Right-hand cutting direction is standard for NPT pipe threads.

High-speed steel with TiN coating manages heat

The high-speed steel substrate and TiN coating reduce friction and heat buildup during hand or machine tapping. Four flutes provide efficient chip evacuation in ductile pipe materials. Normal use produces typical cutting noise for pipe threading operations. No external power draw applies as the tap is driven by a wrench or tapping head.
