Professional Threading Tool

The Drill America DWTSMR3-50X4 is a high-speed steel round adjustable die designed for creating or repairing external threads on pipes and rods. Its 3 inch outside diameter suits heavy-duty plumbing and industrial maintenance tasks. The adjustable mechanism allows precise fit control for consistent thread quality across repeated use.

Durable HSS Construction

High-speed steel composition provides extended wear resistance compared to standard carbon steel dies, reducing replacement frequency in demanding environments. Chamfered faces on both sides offer a 2 to 3 thread lead for starting cuts and a 1 to 1-1/2 thread lead for threading near shoulders. The fine-pitch adjustment screw enables accurate diameter control by expanding or contracting the die halves.

Questions about this item

What thread standard does the M50x4 die cut, and what pitch does that cap at?

The die cuts an M50 metric thread with a 4 mm pitch; that pitch is fixed by the die geometry.

What holder or stock is required to mount the 3-inch OD round die?

A die stock or machine holder that accepts a 3-inch outside-diameter round die body is required for mounting.

How is the die adjusted for fit, and which step is commonly missed?

Turn the fine-pitch adjusting screw to open or close the split die; the step often missed is removing the screw when the die is placed in a machine holder so the holder's own screws control the adjustment.
