  • High-speed steel construction extends wear life for threading

M52 x 2.5 thread die

The Drill America DWTSMR3-52x2.5 is a 3 inch outside-diameter high-speed-steel round adjustable die for cutting M52 x 2.5 metric threads. It suits maintenance shops and fabricators who need to produce or repair large-diameter threaded rod and pipe. The die is new and meets the supplier's stated specifications. California Proposition 65 warnings apply for cancer and reproductive-harm substances.

Sustained threading performance

High-speed steel construction gives improved wear life during extended cutting cycles compared with carbon-steel alternatives. Both faces are chamfered: one side offers a 2 to 3 thread lead for starting cuts, the other a 1 to 1-1/2 thread lead for work close to a shoulder. The fine-pitch adjustment screw opens or closes the die halves for precise pitch control under continuous load.

3 inch OD holder compatibility

The 3 inch outside diameter determines fit in standard die stocks and machine holders. When the adjusting screw is removed, the beveled slot allows the holder's own screws to control expansion. Buyers needing a different thread pitch or a smaller die diameter cannot use this part.

Questions about this item

How much power does the DWTSMR3-52x2.5 die draw when running all day?

The die is a hand-operated cutting tool with no motor, so it draws no electrical power and generates no heat during use.

What holder or wrench must I already own to use this 3" OD round adjustable die?

A standard 3-inch outer-diameter die stock or machine holder with adjusting screws is required to clamp and drive the die.

Will the M52 x 2.5 thread pitch work with older British Standard Pipe fittings I have on the shelf?

M52 x 2.5 is a metric coarse thread and is not compatible with BSP or NPT fittings, which use different diameters and pitches.
