Thread size and tap type
The Westward 5TWT5 is a pipe tap for cutting NPT threads at 1/16 inch - 27. It is a semi-bottoming design with four flutes made from high speed steel. This tool suits maintenance technicians and plumbers who need to create or repair tapered pipe threads in metal.
Capacity and headroom
The tap has an overall length of 2 1/8 in and a thread length of 11/16 in. It uses a 75 percent thread drill size C and meets a class of fit 3B. It handles standard NPT thread cutting in compatible materials but is not suited for through-hole tapping or larger pipe sizes.
Uncoated finish and flute count
The bright uncoated surface reduces cost and works well in softer metals. Four flutes provide balanced chip evacuation and thread finish for the specified thread size. No coating or alternative flute configurations are included.

Questions about this item
Will the 1/16"-27 NPT tap cut clean threads in an existing 11/16" deep hole without bottoming out?
The semi-bottoming design with 11/16" thread length lets it cut full threads near the bottom of a blind hole without needing full clearance.
How can I verify the 4-flute tap is producing a correct Class 3B fit during use?
Check thread engagement with an NPT ring gauge; the 75 percent drill size C and 4 flutes should yield a tight, uniform seal when torqued.
Does the bright uncoated high-speed steel tap come with a handle or drill guide in the package?
Only the tap itself is supplied; a compatible tap wrench and the correct size C drill bit must be purchased separately.
