Cleveland C64040 Pipe Tap 3/8"-18 NPT
This Cleveland pipe tap creates internal NPT threads in pipe and conduit fittings. It features a 3/8"-18 thread size and four flutes for efficient chip evacuation. The high-speed steel construction provides durability for general-purpose threading tasks. The semi-bottoming chamfer allows threading close to the bottom of blind holes.
Suited for maintenance
Machinists and plumbers cutting standard taper pipe threads will find this tool matches the 3/8"-18 specification. The bright, uncoated finish suits standard steel and iron materials. Shops needing coated taps for stainless steel or high-temperature alloys should consider other options. Users requiring bottoming taps for full-depth blind holes need a different chamfer style.
Bright uncoated finish and four-flute design
The uncoated high-speed steel surface works well in typical ferrous materials without the cost of specialised coatings. Four flutes balance chip clearance with thread finish quality on the 3/8"-18 pitch. The semi-bottoming lead reduces the torque needed to start the thread compared to a bottoming tap. No additional accessories or lubricants are included with the tap.

Questions about this item
What size drill bit do I need to prepare the hole for the 3/8"-18 NPT tap?
Use a 0.5625 in drill bit to produce the 75 percent thread depth required for this 3/8"-18 NPT tap.
Will the semi-bottoming design let me finish threads in a blind hole that my older taper taps could not reach?
Yes, the semi-bottoming chamfer cuts closer to the bottom of a blind hole than a taper tap, letting you complete threads deeper in existing workpieces.
How can I confirm the threads I cut match the 3/8"-18 NPT specification after tapping?
Check the finished threads with an NPT 3/8"-18 thread plug gauge; a proper fit confirms the tap produced the correct taper and pitch.
