Cleveland 3/8"-18 NPT Pipe Tap
The Cleveland C56704 is a semi-bottoming pipe tap designed for cutting 3/8"-18 NPT threads in pipe and conduit. It suits maintenance technicians and fabricators who need to create or repair tapered pipe threads in metal assemblies.
Four-flute high-speed steel with TiN coating
Four flutes on high-speed steel provide balanced chip evacuation while the TiN coating reduces friction during extended threading operations. The semi-bottoming chamfer allows threading closer to the bottom of a blind hole without the aggressive cut of a bottoming tap.
Verify 0.5625 in drill size and right-hand threads
Confirm the workpiece material suits high-speed steel and that a 75 percent thread depth matches the joint specification. The tap cuts right-hand threads only; ensure the application does not require left-hand orientation before ordering.

Questions about this item
Does the Cleveland C56704 tap generate much heat when threading 3/8"-18 NPT holes all day?
Cutting heat depends on cutting fluid, speed and workpiece material; the tap itself is high-speed steel with TiN coating to resist wear during extended use.
What drill bit must I already have to prepare the hole for this 3/8"-18 NPT tap?
The specified drill size is 0.5625 in (9/16 in) for 75 percent thread engagement before tapping.
Will this 4-flute semi-bottoming tap work in my older manual tap wrench?
Yes, the square shank fits standard tap wrenches and the right-hand 4-flute design is compatible with conventional hand-threading setups.
