1-1/4"-10 HSS Round Adjustable Die

The Drill America DWTSR212-11410 is a high-speed steel round adjustable die for cutting 1-1/4"-10 threads. It suits machinists and maintenance technicians who need to produce or repair external threads on rods, pipes or studs. The tool is supplied new and carries California Proposition 65 warnings for cancer and reproductive harm.

Build Quality and Daily Use

The die body is made from high-speed steel for improved wear life during threading operations. Both faces are chamfered: one side has a 2 to 3 thread chamfer for general threading, the other a 1 to 1-1/2 thread chamfer for threading close to a shoulder. A fine-pitch adjustment screw opens or closes the die, and the bevelled slot permits holder-based adjustment when the screw is removed.

Practical Limits of Adjustable Dies

Adjustable dies rely on spring tension and screw adjustment, so thread accuracy depends on operator skill and holder rigidity. They are not intended for high-volume production where solid dies maintain tighter tolerances. The HSS material resists wear better than carbon steel but still dulls on abrasive or hardened workpieces. Users needing larger diameters or different pitches must select a separate die.
