Description

The RIDGID 47770 Right-Handed High-Speed Pipe Threading Die Set gives you four HSS dies engineered for clean, accurate NPT threads on 1-inch to 2-inch pipe. These universal dies are compatible with RIDGID die heads like the 504A, 711, 713, 811A, 815A, 816, 817, and 842, making them a flexible choice for a professional threading setup.

RIDGID 47770 Pipe Die Set: Precise Threads for 1-Inch to 2-Inch NPT

Each die in this set is ground to cut right-hand NPT threads at 11-1/2 TPI. The high-speed steel construction maintains its cutting edge longer than carbon steel, so you spend less time sharpening and more time running pipe. Whether you're threading black iron, galvanized, or stainless pipe, these dies deliver the consistency your joints need.

Compatibility Across RIDGID Die Heads

Designed for RIDGID universal die heads, this set is ready to work with machines that use 504A, 711, 713, 811A, 815A, 816, 817, or 842 die heads. That broad compatibility means you can move between stations without buying a new set for each machine.

Durable Construction for Heavy Use

The high-speed steel material resists heat and wear, extending tool life in demanding environments. The dies are precision-ground to hold tolerance, so you get clean threads with less effort.

Care for Long Service Life

Use cutting oil during threading to reduce heat and protect the cutting edge. After each job, clean the dies and lightly coat them with corrosion inhibitor.

Product Details

Choose the Right Die Material

Carbon steel is fine for occasional use, but high-speed steel keeps an edge longer when you're threading lots of pipe. The RIDGID 47770 set is a solid investment if you're working on threaded water lines, handrails, or structural pipe.

Threading Tips for Clean Threads

Start with a beveled pipe end, apply cutting oil generously, and keep a steady speed. Back the die off periodically to break chips.

Frequently Asked Questions

Will these dies fit a RIDGID 300 Power Drive?

Yes, with a compatible universal die head such as the 504A, 711, or similar, these dies will work.

What sizes are included?

The set includes dies for 1", 1-1/4", 1-1/2", and 2" pipe.

Do they require a die head?

Yes, these are replacement dies that fit into a RIDGID universal die head, not a standalone tool.

Are they suitable for stainless steel?

HSS dies can cut stainless, but use slower speed and proper cutting oil.

How do I identify each die?

Each die is stamped with its size and TPI.

Sharp dies, make perfect threads.

Clean threads

I've used these on a bunch of jobs already. They thread 1 to 2 inch pipe cleanly and the high speed steel holds its edge. Much better than the set I had before.

Good set

Good dies. A little pricey but you get what you pay for. I've cut several threads and they come out smooth. The set covers the common sizes, so it's convenient.

Worked fine on my projects. Instructions could be clearer, but the dies themselves are solid.
