1/2"-56 HSS Round Adjustable Die

The Drill America DWTSR1-1256 is a high speed steel round adjustable die designed for threading operations. It produces 1/2"-56 threads with a 1 inch outside diameter. The tool suits machinists and maintenance technicians who need to cut or repair external threads on rods or pipes.

Replaces worn or fixed-size dies

Adjustable dies replace fixed dies when thread fit must be tuned for specific applications. The fine pitch adjustment screw lets the user open or close the die to achieve a tighter or looser class of fit. The jump is worth it when a standard die produces threads that are too tight for assembly or too loose for sealing.

Practical limits of round adjustable dies

The die uses a slot and screw mechanism that requires a compatible die stock or machine holder for proper operation. Adjustment range is limited by the screw travel and the die material elasticity. California Proposition 65 warnings apply because the product contains chemicals known to cause cancer and reproductive harm.

Questions about this item

What die stock or holder fits the 1" outside diameter of this die?

Use a standard 1" round die stock or machine holder that accepts a 1" OD die; the bevelled adjusting slot lets the holder's own screws control adjustment.

How do I adjust the thread size on the DWTSR1-1256 die?

Turn the fine-pitch adjusting screw to open or close the split die; for machine holders, remove the screw and use the holder's adjusting screws instead.

When should I replace this HSS round adjustable die?

Replace it when the cutting edges dull enough to produce rough threads or require excessive force; HSS gives long wear life but is not resharpenable.
