Threading tool for 1/2"-56 threads

This high-speed steel round adjustable die cuts external threads on rod or pipe with a 1/2"-56 thread specification. It is intended for machinists, maintenance technicians and plumbing professionals who need to produce or repair this specific thread form in workshop or field conditions.

Wear resistance under continuous cutting

The high-speed steel construction provides improved wear life compared to carbon steel dies when threading tougher materials or making repeated cuts. Chamfers on both faces — a 2 to 3 thread lead on one side and a 1 to 1-1/2 thread lead on the other — allow the die to start cleanly and also thread close to a shoulder without binding during extended use.

Adjustable fit with holder compatibility

Thread size is set by a fine-pitch adjusting screw that opens or closes the die halves; the screw can be removed so the die is adjusted entirely by the holder's own screws when mounted in a machine holder. The bevelled slot permits this changeover, but the die requires a compatible 1-1/2" OD holder and careful alignment to avoid tapered or oversize threads.

Questions about this item

Does the 1/2"-56 HSS die generate noticeable heat during extended threading sessions?

High Speed Steel construction resists wear and dissipates heat effectively during continuous cutting operations.

What holder or handle is required to operate this 1-1/2" OD round die?

A standard 1-1/2" outer-diameter die stock or machine holder with internal adjusting screws accepts the beveled slot design.

Can the chamfered faces on this die thread closer to shoulders than my current un-chamfered dies?

One face has a 1 to 1-1/2 thread chamfer specifically for threading near shoulders, while the opposite face offers a 2 to 3 thread chamfer for general starts.
