Threading die for 1/2"-36 threads

The Drill America DWTSR112-1236 is a high-speed steel round adjustable die cut for a 1/2"-36 thread form. It suits maintenance technicians and machinists who need to cut or repair external threads on rod or pipe. The die is new and intended for use in a die stock or machine holder. California Proposition 65 warnings apply to this product.

Chamfered faces and fine-pitch adjustment

Both faces are chamfered: one side offers a 2 to 3 thread lead for starting a cut, while the other provides a 1 to 1-1/2 thread lead for work close to a shoulder. A fine-pitch screw opens or closes the die halves for precise fit. The adjusting screw can be removed so that a machine holder's own screws control the setting.

Fixed 1/2"-36 thread form limits use

The die cuts only 1/2"-36 external threads; it cannot produce other diameters or pitches. Adjustment range is limited to the fine-pitch screw travel, so it cannot compensate for heavily worn or oversized blanks. High-speed steel resists wear but is not suited for very hard or abrasive workpiece materials.

  • Adjustable fine-pitch screw allows precise thread fit control
  • Chamfered both faces with 2-3 thread lead for easy starting

  • Compatible with machine holders via removable adjusting screw

Questions about this item

Will the 1/2"-36 HSS die need replacement once the adjustment screw wears?

The fine-pitch adjustment screw forces the die halves apart or lets them spring together, so the die can be re-tightened as the cutting edges wear, extending service life.

What limits continuous threading with this 1-1/2" OD round die?

Heat buildup in the high-speed steel cutting faces is the first limit during sustained use; use cutting fluid and allow cooling intervals.

Does the HSS round adjustable die generate excess heat or noise when run all day?

High-speed steel runs hotter than carbon steel under prolonged cutting; apply ample lubricant and pause periodically to control temperature.
