Threading Die for 1/2"-60 Threads

The Drill America DWTSR1-1260 is a high-speed steel round adjustable die designed to cut or repair external threads on pipe or rod. It suits maintenance technicians and plumbers who need a durable tool for creating precise 60-thread-per-inch connections. The die is new and supplied as a single piece for professional use.

1-Inch Outside Diameter Fits Standard Holders

The single specification that decides fit is the 1-inch outside diameter, which matches common die stocks and machine holders. This dimension ensures the die seats correctly in the holder you already own, so the threads you cut align with the mating part. Verify your holder accepts this diameter before purchasing.

Adjustable Design Maintains Accuracy Over Repeated

A fine-pitch adjustment screw lets you open or close the die slightly, compensating for wear so thread dimensions stay consistent across many cuts. Chamfers on both faces — 2 to 3 threads on one side, 1 to 1-1/2 on the other — allow starting new threads and threading close to shoulders without binding. High-speed steel construction resists dulling during sustained threading operations.

Questions about this item

What does the 60 threads-per-inch figure mean when I use this die on a workpiece?

It produces a very fine 1/2"-60 thread pitch, giving a tight, precise fit for applications that require close tolerances and strong engagement.

How does the adjustable screw mechanism cap the thread size I can cut?

The fine-pitch adjusting screw expands or contracts the die halves, letting you set the thread diameter within a narrow range around the nominal 1/2" size.

What holder or handle do I need to mount this 1-inch round die?

It fits any standard 1" OD die stock or machine holder that accepts round adjustable dies with a beveled adjustment slot.
