Cleveland C64109 Pipe Tap

The Cleveland C64109 is a high-speed steel pipe tap designed to cut internal NPTF threads in pipe and conduit fittings. It features a 1/4"-18 thread size with five flutes and a semi-bottoming chamfer for threading close to the bottom of a hole. The bright, uncoated finish suits general-purpose tapping in ferrous and non-ferrous materials. Right-hand cutting direction matches standard thread requirements.

Who this suits, who it does not

This tap suits maintenance technicians and pipefitters creating pressure-tight NPTF connections in 1/4 inch pipe. The semi-bottoming design helps when thread depth is limited by a shoulder or blind hole. It is not for through-hole tapping where a taper or plug chamfer clears chips more efficiently. Buyers cutting larger diameters, different thread standards, or left-hand threads need a different tool.

1/4"-18 NPTF thread size

The defining specification is the 1/4"-18 NPTF thread size, which determines compatibility with the pipe fitting being threaded. The 75 percent thread drill size of .4375 in guides the required tap drill selection for proper thread engagement. Using an incorrect drill size or thread standard will produce a non-sealing joint. Verify the workpiece material and hole depth match the tap’s high-speed steel construction and 1 1/16 in thread length.
