Threading die M39 x 2.5

The Drill America DWTSMR212-39X2.5 is a high-speed steel round adjustable die for cutting M39 x 2.5 threads. It suits maintenance and repair technicians who need to create or restore external threads on pipe or rod stock.

Sustained wear life

High-speed steel construction gives improved wear life during repeated threading operations. The die is chamfered on both faces, with a 2 to 3 thread lead on one side and a 1 to 1-1/2 thread lead on the other for work close to a shoulder. Adjustment is made by a fine-pitch screw that spreads or closes the die halves.

Installation notes

The die fits standard 2-1/2 inch OD holders; the beveled slot allows the adjusting screw to be removed so the holder’s own screws can control size. No machine-holder adjustment screws are included. California Proposition 65 warnings apply for cancer and reproductive harm.

Questions about this item

Does the M39 x 2.5 thread die generate noticeable heat during extended hand-threading sessions?

High-speed steel resists heat build-up better than carbon steel, so the die stays cooler during long cuts.

What holder or handle is required to use this 2-1/2" OD round adjustable die?

A standard 2-1/2" die stock or machine holder with internal adjusting screws is needed to drive and adjust the die.

Will this die cut threads on older mild-steel pipe that has work-hardened over time?

The HSS material and adjustable split design handle work-hardened material more cleanly than fixed carbon-steel dies.
