Threaded pipe tap for NPT connections

This Westward 5TWU1 pipe tap cuts internal threads for 3/4"-14 NPT pipe fittings. It is made from high-speed steel with a bright uncoated finish and a right-hand cutting direction. The semi-bottoming chamfer allows threading close to the bottom of a blind hole. Five flutes provide balanced chip evacuation for general-purpose threading tasks.

Sustained cutting performance in steel and iron

The high-speed steel construction maintains edge retention during repeated threading operations in ferrous materials. A 75 percent thread drill size of .9063 in prepares the hole for proper thread engagement. The 3B class of fit produces a standard precision thread suitable for pressure-tight joints. Five flutes distribute cutting load evenly to reduce tap wear over long production runs.

Semi-bottoming chamfer limits blind-hole depth

The semi-bottoming design restricts use to holes where the thread does not need to reach the absolute bottom. Through-holes or deep blind holes with clearance are the intended applications. Buyers who need full-bottom threading in shallow blind holes cannot use this tap. The fixed 3/4"-14 NPT size also excludes any metric or straight-thread requirements.

Questions about this item

How much heat does the 5-flute high-speed steel tap generate when cutting NPT threads all day?

The bright uncoated high-speed steel construction resists heat build-up during extended threading, and the five-flute design distributes cutting load evenly to keep temperatures manageable.

What size drill bit must I already own to prepare the hole for this 3/4"-14 NPT tap?

A drill bit of .9063 in is required to produce the 75 percent thread depth this tap is designed for.

Will the 1 3/8 in thread length and 3B class of fit match the fittings on my older pipe system?

The tap cuts a standard NPT thread profile with a 1 3/8 in thread length and 3B fit, compatible with existing NPT components that follow the same specification.
