M45×4 Threading Die

This Drill America adjustable die cuts M45×4 external threads using high-speed steel for extended wear life. It measures three inches in outside diameter and is designed for pipe and tubing work in plumbing and automotive maintenance.

For External Thread Cutting Only

The tool creates male threads on rods or pipe ends; it cannot cut internal threads or chase damaged threads. Buyers needing internal threads, smaller diameters or different pitch standards should select a tap or a die with the matching specification.

M45×4 Thread Specification

The die is calibrated exclusively for a 45 mm nominal diameter with a 4 mm pitch. Using it on any other thread size or pitch will produce incorrect threads and damage both the workpiece and the die.

  • High Speed Steel construction extends die wear life
  • Adjustable fine-pitch screw allows precise thread fit
  • Dual chamfers enable threading and shoulder work

Questions about this item

Will this M45×4 die fit the same die stock I use for smaller round dies?

The die has a 3" outside diameter, so it requires a die stock or holder that accepts 3" round dies.

How can I confirm the die is cutting the correct thread pitch after setup?

Thread a known-good M45×4 nut onto the freshly cut threads; it should turn freely for the full engagement length.

Does the package include a die stock or handle, or must I supply my own?

Only the HSS round adjustable die is included; a compatible 3" die stock or holder is sold separately.
