ZORO SELECT 5TWY3 Pipe Tap
This Westward ZORO SELECT 5TWY3 pipe tap cuts internal NPT threads with a 3/4"-14 thread size. It features a semi-bottoming chamfer and five flutes made from high speed steel with a TiN coating. The tool has an overall length of 3 1/4 inches and a thread length of 1 3/8 inches. It produces a Class 1B fit with a 75 percent thread drill size of .9063 inches.
Build integration and requirements
The tap requires a pre-drilled hole of .9063 inches to achieve the specified 75 percent thread depth. Its right-hand thread direction and semi-bottoming design allow threading close to the bottom of blind holes. The TiN coating on the high speed steel flutes reduces friction and extends tool life during cutting operations. No external power source or holder is included with the tap itself.
Suitable users and limitations
This tap suits plumbers, pipefitters, and maintenance technicians cutting NPT threads in pipe and conduit. The five-flute design aids chip evacuation in ductile materials. It is not intended for metric thread forms, straight mechanical threads, or left-hand thread applications. Users needing different thread sizes, pitch diameters, or thread classes must select alternative tooling.
Highlights
- NPT threading for standard pipe connections
- Semi-bottoming design threads close to blind-hole bottoms
- Five flutes clear chips efficiently during tapping
- High-speed steel with TiN coating resists wear
- Right-hand cut matches common pipe-thread requirements

Questions about this item
How deep can the 3/4"-14 NPT tap cut threads in a single pass?
The thread length is 1 3/8 inches, so the tap cuts that depth before needing to back out and clear chips.
Does the TiN-coated high-speed steel tap run hot enough to need cutting fluid during long threading jobs?
TiN reduces friction and heat buildup, but pipe taps still generate significant heat in steel; use a suitable cutting oil to protect the coating and extend tool life.
What size drill bit must I have on hand before tapping a 3/4"-14 NPT hole?
A 0.9063-inch drill bit is required to produce the 75 percent thread depth this tap is designed for.
