Threading die for 1/4"-36 threads

This Drill America round adjustable die cuts external 1/4"-36 threads with a 1-1/2 inch outside diameter. It is made from high speed steel for improved wear life during threading operations. The die suits maintenance, repair and small-batch production where adjustable thread fit is required.

Chamfered faces and fine-pitch adjustment

Both faces are chamfered: one side has a 2 to 3 thread chamfer for starting threads, the other a 1 to 1-1/2 thread chamfer for threading close to a shoulder. A fine-pitch screw forces the die halves apart or lets them spring together for precise fit control. The bevelled slot allows the adjusting screw to be removed when the die is mounted in a machine holder.

Replaces fixed dies when fit must be tuned

This adjustable die replaces solid round dies when thread class or clearance needs fine tuning on the job. The jump is worth it for shops that regularly chase threads to different standards or repair damaged threads without changing tooling. It is not for internal threading, pipe-thread standards or high-volume automated lines that demand carbide tooling.

Questions about this item

What thread standard does the 1/4"-36 die cut, and what fit does it produce?

It cuts a 1/4"-36 thread using High Speed Steel for longer wear; the adjustable screw lets you open or close the die to hit the exact class of fit you need.

What holder size does the 1-1/2" outside diameter require?

The die measures 1-1/2" across, so it fits any standard 1-1/2" round die stock or machine holder made for that OD.

How do you set the die in a machine holder, and what step is often missed?

Remove the die's own adjusting screw, seat the die in the holder, then use the holder's adjusting screws to set the thread size — skipping the screw removal prevents proper adjustment.
