Wheeler-Rex 847745 NPT Dies 1/2-3/4
The Wheeler-Rex 847745 set supplies four universal threading dies for pipe sizes from 1/2 inch to 3/4 inch. They are designed for use with compatible threading machines and accept die heads referenced by part numbers such as 504A, 711, 713, 811A, 815A, 816, 817, 842, 97065 and 897065. The package contains four dies ready for pipe threading tasks.
Suits pipe-threading professionals using supported
These dies suit technicians who operate threading machines equipped with the listed compatible die heads and need to cut NPT threads on 1/2 to 3/4 inch pipe. They do not suit users who require dies for larger or smaller pipe diameters, different thread standards, or machines that do not accept the specified die head part numbers.
Package quantity of four dies determines job
The single specification that decides fit is the package quantity of four dies covering the 1/2 to 3/4 inch range. This quantity dictates how many threading operations can be performed before reordering and confirms the exact pipe size window the set addresses.

Questions about this item
How do I install these NPT dies into a compatible die head without damaging the threads?
Match the die set to a listed compatible head such as 504A, 711, 713, 811A, 815A, 816, 817, 842, 97065, or 897065, then seat each die squarely in its slot before tightening the head clamp.
What replacement schedule should I follow for the four dies when threading 1/2 in to 3/4 in pipe daily?
Inspect cutting edges after every few hundred threads; replace individual dies when teeth show rounding or when thread quality drops, rather than waiting for a fixed interval.
At what point does heat buildup limit continuous threading with this UDH die set on a threading machine?
Sustained cutting on steel pipe will dull the die edges before the machine overheats; pause to apply cutting oil and let the dies cool when thread finish degrades.
