Cleveland C56706 Pipe Tap 3/4"-14 NPT
The Cleveland C56706 is a semi-bottoming pipe tap designed for cutting NPT threads in pipe and conduit. It suits maintenance technicians and plumbers who need reliable internal threading for 3/4 inch connections. The five-flute high-speed steel body with TiN coating provides durability for repeated use. It is not intended for through-hole tapping where a taper or plug chamfer would be more appropriate.
3/4"-14 thread size with five flutes
This tap cuts a 3/4"-14 NPT thread form with an overall length of 3 1/4 inches and a thread length of 1 3/8 inches. The 75 percent thread drill size is 0.9063 inches, giving the necessary clearance for the semi-bottoming design. Five flutes offer efficient chip evacuation in ductile materials. It reaches its limit in blind holes shallower than the thread length where chips cannot clear the flutes.
High-speed steel with TiN coating
The high-speed steel substrate resists wear during hand or machine tapping operations. TiN coating reduces friction and heat buildup at the cutting edges, extending tool life in steel and iron. Power draw and noise depend entirely on the driving tool and workpiece material. The tap itself adds negligible thermal load beyond the cutting zone.

Questions about this item
Will the 3/4"-14 NPT tap work with my existing 0.9063 in drill bits for 75 percent thread engagement?
Yes, the specified 75 percent thread drill size is 0.9063 in, matching standard drill bits for this NPT thread size.
How can I confirm the TiN-coated high-speed steel tap is cutting clean NPT threads during use?
Check for consistent chip formation across all five flutes and verify the tapered thread profile matches the 1 3/8 in thread length specification.
Does the Cleveland C56706 package include a tap handle or wrench for the 3 1/4 in overall length tool?
The tap is sold individually; a compatible tap wrench for the 3/4"-14 NPT size must be purchased separately.
