Threading die for M46x3 pipe

This Drill America round adjustable die cuts M46x3 threads on pipe and tubing. The high-speed steel construction provides extended wear life for repeated threading tasks. It suits plumbers and maintenance technicians who need reliable thread cutting on large-diameter pipe work.

Chamfered faces for smooth starts

Both faces are chamfered to ease thread engagement. One side offers a 2 to 3 thread chamfer for standard threading while the other provides a 1 to 1-1/2 thread chamfer for work close to a shoulder. The fine-pitch adjustment screw controls the die opening for accurate thread sizing.

Replaces fixed dies when fit matters

This adjustable die replaces fixed-size dies when thread fit must be tuned for specific connections. The fine-pitch screw allows precise adjustment for tighter or looser thread engagement. The jump is worth it when threading close to shoulders or when standard fixed dies cannot achieve the required fit. California Proposition 65 warnings apply.

Questions about this item

How do I install the M46x3 3" OD HSS round adjustable die in a machine holder, and what step is often missed?

Remove the die's adjusting screw, place the die in the holder, then use the holder's adjusting screws to open or close the die; the missed step is forgetting to remove the die's own screw first.

What maintenance will this high-speed steel die need over time?

Apply cutting fluid during each use, clean chips from the threads after threading, and store the die dry to prevent corrosion; the fine-pitch adjustment screw should move freely.

At what point does thread wear become the limiting factor during sustained threading?

The high-speed steel cutting edges dull gradually; when threads become oversized or surface finish degrades, the die can no longer hold the M46x3 pitch diameter within tolerance.
