1-1/2"-20 HSS Round Adjustable Die

The Drill America DWTSR212-11220 is a high-speed steel round adjustable die for cutting 1-1/2"-20 threads on pipe or rod. It is intended for professional plumbers, maintenance technicians and machinists who need a durable threading tool with adjustable fit. The die features chamfers on both faces to suit different starting conditions and shoulder clearance.

Not for non-adjustable or hand-tap-only jobs

This die suits users who require an adjustable thread form for precise fit or long production runs where wear compensation matters. It is not for buyers who need a fixed solid die, a hex die for wrench use, or a tap for internal threads. Anyone without a compatible die stock or machine holder should look at a different tool type.

Fits standard die stocks and machine holders

The round body with a fine-pitch adjustment screw drops into standard die stocks and can be used in machine holders by removing the screw and using the holder's own adjusting screws. The bevelled slot allows this changeover without disassembly of the holder. The main installation issue is applying uneven pressure, which can produce tapered or chattered threads.

Questions about this item

What size die stock or handle is required for the 2-1/2" outer diameter of this round adjustable die?

A die stock or machine holder with a 2-1/2" capacity is needed to fit the outer diameter of this round adjustable die.

Can this 1-1/2"-20 HSS die be used to repair threads on older mild-steel bolts and pipe nipples?

Yes, the high-speed steel cutting edges are harder than mild steel, so the die can clean up or recut threads on older bolts and pipe nipples.

How do I verify the die is cutting a correct 1-1/2"-20 thread after setup?

Check the finished thread with a 1-1/2"-20 thread gauge or screw on a matching 1-1/2"-20 nut; it should engage smoothly over the full length.
