Threading die for M48x4 threads

The Drill America DWTSMR3-48X4 is a 3" OD high-speed steel round adjustable die designed for cutting external M48x4 threads. It suits maintenance technicians and machinists who need to produce or repair coarse-pitch threads on large-diameter rod or pipe. The tool is supplied new and carries a California Proposition 65 warning for chemicals known to cause cancer and reproductive harm.

M48x4 coarse thread specification

The single specification that determines fit is the M48x4 thread form; the die cuts a 48 mm nominal diameter with a 4 mm pitch. No other thread standard or pitch is compatible, so the workpiece must match this exact size and thread series before cutting begins.

Dual chamfer and adjustable slot

Both faces are chamfered: one side has a 2 to 3 thread lead for starting cuts, the other a 1 to 1-1/2 thread lead for threading close to a shoulder. A fine-pitch adjustment screw opens or closes the die, and the beveled slot allows the screw to be removed so the die can be adjusted from the machine holder instead.

Questions about this item

What does the M48 x 4 size mean when I use this die in my machine?

The M48 x 4 designation indicates a 48 mm major diameter with a 4 mm thread pitch, so the die cuts metric threads of that exact size on compatible round stock.

How does the adjustable mechanism work with a standard die holder?

The die has a beveled slot allowing the fine-pitch adjusting screw to be removed; once in a machine holder you use the holder's own adjusting screws to open or close the die.

What physical dimensions let this 3 inch OD die fit my existing tooling?

The die measures 3 inches outside diameter, a standard size that fits common 3 inch die stocks and machine holders without adapters.
