Westward 1/4"-18 NPT Pipe Tap
The Westward 5TWY0 cuts internal NPT threads in pipe and conduit fittings. Its semi-bottoming design and four-flute high-speed steel body suit maintenance technicians and plumbers who need reliable thread engagement in ferrous and non-ferrous metals.
High-speed steel with TiN coating
The TiN-coated high-speed steel resists wear during hand or machine tapping. Right-hand cutting action produces clean threads at standard 75 percent drill size of .4375 in. Thread length reaches 1 1/16 in within an overall length of 2 7/16 in, meeting Class 3B fit requirements.
Four-flute semi-bottoming geometry
Four flutes improve chip evacuation and reduce tap breakage in through or blind holes. The semi-bottoming chamfer starts threads easily while cutting close to the bottom of a drilled hole. No lubricants, handles or guides are included with the tap.

Questions about this item
How do I install the 1/4"-18 NPT pipe tap and what step is often missed?
Drill the hole to the 75 percent thread drill size of .4375 in, then run the tap right-hand with cutting fluid; the step many skip is using the correct drill size for a Class 3B fit.
What maintenance or replacement will this High Speed Steel TiN tap need later?
The TiN coating reduces wear, but the four flutes will dull over time; replace the tap when threads show tearing or the 1 1/16 in thread length no longer cuts cleanly.
What limit appears first under sustained use of this 4-flute semi-bottoming tap?
Heat buildup in the High Speed Steel body is the first limit; continuous cutting without coolant reduces edge life and can cause the tap to bind in the 2 7/16 in overall length.
