Threading die for M31x2 pipe

This high-speed steel round adjustable die cuts M31x2 threads on pipe and tubing. It is made for plumbers and maintenance technicians who need to repair or create external threads in the field or shop. The tool is supplied new and carries a California Proposition 65 warning for chemicals known to cause cancer and reproductive harm.

Heat and power in normal use

Thread cutting generates heat at the contact zone, so cutting fluid is normally applied to control temperature and extend tool life. The high-speed steel construction resists wear during repeated manual or machine threading operations. No electrical power is drawn by the die itself; load depends entirely on the drive tool used.

Chamfer and adjustment details

Each face features a different chamfer: one side offers a 2 to 3 thread lead for starting cuts, while the opposite side provides a 1 to 1-1/2 thread lead for threading near a shoulder. A fine-pitch adjustment screw opens or closes the die for precise fit, and the bevelled slot allows holder-based adjustment when the screw is removed.

Questions about this item

How do I install the DWTSMR212-31X2 die and which chamfer side should face the workpiece?

Mount the die in a holder, align it with the rod, and use the 2-to-3-thread chamfer side for starting new threads; the 1-to-1½-thread chamfer side is for threading close to a shoulder.

What maintenance or replacement will this HSS adjustable die need over time?

The high-speed steel cutting edges wear gradually; when thread quality drops, the die can be opened slightly via the fine-pitch adjustment screw to restore size, and is replaced once adjustment no longer produces clean threads.

What limit appears first during sustained threading with this 31 mm die?

Heat buildup in the high-speed steel body and cutting faces is the first limiting factor, causing accelerated wear and reduced thread finish if cutting fluid is not used or if feed rate is too aggressive.
