1/2"-16 HSS Adjustable Threading Die

The Drill America DWTSR112-1216 is a high-speed steel round adjustable die for cutting 1/2"-16 threads on pipe or rod. It suits maintenance technicians and plumbers who need reliable thread cutting on steel or iron. The die is supplied new and carries a California Proposition 65 warning for chemicals known to cause cancer and reproductive harm.

Chamfered Faces For Threading Control

Round dies are chamfered on both faces to manage thread starts and finishes. One side offers a 2 to 3 thread chamfer for general threading, while the other provides a 1 to 1-1/2 thread chamfer for work close to a shoulder. Adjustment uses a fine-pitch screw that spreads the die sides or lets them spring together for diameter control.

Beveled Slot For Machine Or Hand Use

The adjusting slot is beveled so the screw can be removed when the die sits in a machine holder, letting the holder’s own screws take over adjustment. In hand use the screw stays in place for direct control. High-speed steel construction gives improved wear life over carbon steel equivalents. The tool is not suited for internal thread cutting or for non-metallic materials such as plastic pipe.

Questions about this item

Should I choose the 1/2"-16 die or a different thread size?

Select the 1/2"-16 die when you need to cut or repair 1/2"-16 threads; choose a different die for any other thread pitch or diameter.

What does the 1/2"-16 specification mean when the die is in use?

It cuts or restores a 1/2" diameter thread with 16 threads per inch, and the adjustable screw lets you widen or narrow the fit for class 2A or 3A tolerance.

How does the round adjustable design affect threading on a machine holder?

The bevelled slot lets you remove the adjusting screw and control the die with the holder's own adjusting screws for precise machine threading.
