Threading die for 7/8"-30 pipe
This high-speed steel adjustable die cuts external threads on pipe or tubing with a 7/8"-30 pitch. The round design fits standard die stocks and machine holders for manual or powered threading work. Chamfers on both faces allow starting threads and cutting close to a shoulder.
Replaces worn or fixed-size dies
An adjustable die compensates for wear by opening or closing via a fine-pitch screw, extending service life compared with solid dies. The jump is worth it when thread fit must be tightened over time or when a single die must cover slight diameter variation.
Limited to 7/8"-30 thread form
The die only produces this specific thread size and pitch; it cannot cut other diameters or thread standards. California Proposition 65 warnings apply because the product contains chemicals known to cause cancer and reproductive harm.

Questions about this item
What die holder or handle accepts the 2" OD round body?
Use a standard 2" outside-diameter die stock or machine holder that clamps the round body; the beveled slot lets you remove the adjusting screw for holder-based adjustment.
Which side of the die do I start threading with for a through-hole?
Start with the 2-to-3-thread chamfer side; it guides the die onto the rod and cuts the full thread form before the finer chamfer engages.
When should I replace this HSS die?
Replace it when the cutting edges no longer produce clean threads or when the adjustment screw can no longer open the die enough for the 7/8"-30 pitch.
