Threading die for M50x5 pipe

The Drill America DWTSMR3-50X5 is a 3-inch outside-diameter high-speed steel round adjustable die cut for M50x5 threads. It serves plumbers and maintenance technicians who need to cut or repair external threads on large-diameter pipe and tubing. The HSS construction gives longer wear life than carbon-steel alternatives when working in steel, stainless steel or tough alloys.

Fits standard 3-inch die stocks

The die mounts in any holder that accepts a 3-inch round die, so it works with existing die stocks, ratchet handles or machine holders. Its fine-pitch adjusting screw lets you open or close the thread form without removing the die from the holder, saving setup time on the job site. Chamfers on both faces — 2 to 3 threads on the entry side and 1 to 1-1/2 threads on the rear — allow starting a thread and threading close to a shoulder with the same tool.

Adjustable thread fit without extra parts

The built-in adjustment screw changes the effective diameter, so one die covers a range of fit classes and compensates for wear. When the die is locked in a machine holder the screw can be removed and the holder's own adjusting screws take over, giving the same control without additional accessories. California Proposition 65 warnings apply because the product contains a listed chemical.
