Threading Die for M37x3 Threads

The Drill America DWTSMR3-37X3 is a 3-inch outer diameter high-speed steel round adjustable die. It is designed for creating or repairing external M37x3 threads on rods or pipes. Machinists and maintenance technicians select this tool when a durable, adjustable cutting solution is required for this specific thread size.

Wear Resistance and Adjustment

High-speed steel construction provides improved wear life during threading operations. The die features chamfered faces with a 2 to 3 thread lead on one side for starting threads and a 1 to 1-1/2 thread lead on the other for threading near shoulders. A fine-pitch adjustment screw controls the die opening, and the slot is beveled for use in machine holders.

California Proposition 65 Warning

This product contains a chemical known to the State of California to cause cancer and birth defects or other reproductive harm.

Questions about this item

How do I install the 3" OD HSS round adjustable die in a die holder, and what step is often missed?

Insert the die with the 2-to-3 thread chamfer facing the work, secure it in the holder, then remove the die's fine-pitch adjusting screw so the holder's screws control the thread fit — skipping this removal prevents proper adjustment.

What maintenance will this M37x3 HSS die need over time?

Apply cutting fluid during each use to reduce wear on the high-speed steel threads; inspect the chamfered faces for nicks and replace the die when thread quality degrades or the adjustment range is exhausted.

What limit appears first when threading M37x3 material continuously with this die?

Heat buildup in the high-speed steel cutting edges reduces hardness and dulls the threads faster than the adjustable mechanism reaches its travel limit, so pause to cool the die during long runs.
