Cleveland C55680 Pipe Tap for NPTF Threads

The Cleveland C55680 is a pipe and conduit thread tap designed to cut NPTF threads. It features a 1/16"-27 thread size with four flutes and a semi-bottoming chamfer. The tool is made from high speed steel with a TiN coating for wear resistance.

Suited for right-hand NPTF tapping in pipe

This tap suits mechanics and fabricators who need to create internal NPTF threads in pipe fittings or conduit. The 75 percent thread drill size C specification matches standard tap drill charts for this thread form. Buyers who require a different thread standard, a larger diameter, or a taper or bottoming chamfer style should look at other options.

Handles 1/16"-27 NPTF threads

The four-flute design provides chip clearance for the 11/16 in thread length in a single pass. The TiN coated high speed steel offers durability when cutting ferrous materials. The semi-bottoming chamfer limits use in blind holes that require full thread depth to the bottom.
