Cleveland C64041 Pipe Tap

The Cleveland C64041 is a high-speed steel pipe tap designed for cutting internal NPT threads. It features a 1/2"-14 thread size with a semi-bottoming chamfer and four flutes for efficient chip evacuation. This tool is intended for maintenance and fabrication tasks requiring tapered pipe threads.

Suited for mechanics creating new threads

This tap suits mechanics and fabricators cutting fresh NPT threads in pipe and conduit fittings. The semi-bottoming design allows threading close to the bottom of blind holes. It is not for buyers needing a taper or plug chamfer for through-hole work, nor for those requiring a coated tool for extended life in abrasive materials.

Bright finish and drill size guidance

The bright, uncoated finish provides a clean cutting surface for general-purpose steel and iron applications. The specifications list a 75 percent thread drill size of .7031 inches, guiding the user to the correct hole preparation. The four-flute geometry balances strength and chip clearance during the threading operation.

How do I verify the thread after tapping?

Check with an NPT thread gauge; the 75 percent thread drill size is 0.7031 in.
