NPT pipe threading dies 1 to 2 in

These dies cut National Pipe Taper threads on alloy, conduit, galvanised steel, iron and steel pipe from one inch to two inches. They fit Rothenberger R Series die heads and the Ropower 50R threading machine. The set contains four right-hand high-speed steel dies with 11 1/2 threads per inch.

Sustained threading on heavy pipe

High-speed steel construction resists wear during long production runs on tough materials such as galvanised and alloy pipe. The four-die arrangement distributes cutting load evenly, reducing heat build-up when multiple joints are cut in succession. Compatibility with the Ropower 50R machine ensures stable feed and consistent thread quality over extended sessions.

Upgrade from worn or undersized die sets

Replaces dull dies that produce loose or tapered threads on larger diameter pipe. The jump is worth it when thread quality on one-inch to two-inch pipe becomes unreliable or when switching to high-speed steel for longer service life. Not suited for left-hand thread applications or pipe sizes outside the stated range.

Questions about this item

How much heat or noise does the Rothenberger 00126 die set add when the threader runs all day?

The dies themselves generate no heat or noise; all power draw and sound come from the Ropower 50R machine driving them.

What threader must I already own for these dies to work?

They fit Rothenberger R Series die heads on a Ropower 50R threading machine.

Will the 11 1/2 TPI NPT threads cut by these dies match the fittings on my existing iron pipe?

Yes, the dies cut right-hand NPT threads at 11 1/2 threads per inch, the standard for iron and steel pipe.
