Threading die for M1.4 x 0.3 threads

This Drill America adjustable die cuts external M1.4 x 0.3 threads on rod or pipe. It is made from high-speed steel for improved wear life during threading operations. The 1" outside diameter fits standard die stocks and holders. Machinists and maintenance technicians use it to create or repair fine-pitch metric threads.

Adjustable split design with fine-pitch screw

The die body is split and adjusted by a fine-pitch screw that forces the sides apart or lets them spring together. This allows the user to set the exact thread diameter required for the job. The slot is beveled so the adjusting screw can be removed when the die is mounted in a machine holder that provides its own adjustment mechanism.

Chamfered on both faces for different start

One face has a 2 to 3 thread chamfer for general threading starts, while the opposite face has a 1 to 1-1/2 thread chamfer for threading close to a shoulder. High-speed steel construction maintains cutting edges during sustained use on steel and other ferrous materials. The tool carries a California Proposition 65 warning for chemicals known to cause cancer and reproductive harm.

Questions about this item

How does the M1.4 x 0.3 thread spec translate when cutting threads on a workpiece?

The die cuts a 1.4 mm nominal diameter thread with a 0.3 mm pitch, producing a fine metric thread for small-diameter fasteners.

What does the 1" OD round adjustable die format mean for holder compatibility?

The 1 inch outside diameter fits standard die stocks and machine holders made for 1" round dies, and the fine-pitch adjusting screw lets you open or close the die for fit control.

What physical clearance is needed to use the chamfered faces on this die?

One face has a 2 to 3 thread chamfer for starting threads; the opposite face has a 1 to 1-1/2 thread chamfer for threading close to a shoulder, so plan for that lead-in length.
