Description

The RIDGID 47785 Threading Machine Dies are a four-piece set of right-hand high-speed steel dies for cutting NPT threads on 1/2-inch and 3/4-inch pipe. These dies are built for professional use on black steel, galvanized steel, and softer metals.

Universal compatibility: works with many RIDGID die heads.
Right-hand NPT threads: standard for most plumbing and industrial jobs.

Product Details

Threading Best Practices for Clean, Tight Joints

Good pipe threads start with the right die. The high-speed steel edges on these RIDGID dies stay sharp through repeated use, and the 14 TPI pattern produces threads that seat without binding. Keep the dies aligned and use a proper cutting oil to extend their life and improve thread quality.

Why Compatibility Matters

If you already own a RIDGID universal die head, this set is a drop-in replacement for the sizes you use most. Carrying a single set for 1/2-inch and 3/4-inch jobs saves space and reduces the chance of grabbing the wrong die.

Frequently Asked Questions

Which die heads are compatible?

RIDGID universal die heads 504A, 711, 713, 811A, 815A, 816, 817, and 842.

Can these cut stainless steel pipe?

They are intended for black steel, galvanized steel, and softer metals; stainless requires specialized dies.

How many dies are in the set?

The set includes four dies sized for 1/2" and 3/4" pipe.

Quality dies

I've been a plumber for thirty years, and these dies are first-rate. They cut clean threads on black pipe. They fit my RIDGID die head perfectly.

Great upgrade

I'm a 28-year-old maintenance tech and thread pipe often. These dies are much better than the cheap ones I had before. The teeth are sharp and don't grab. The set covers the most common sizes. They stay aligned and don't wobble. I'm very happy with this purchase.

Good, but make sure you have the holder

The dies are fine, but I didn't realize they need a universal die head. Once I got the holder, they worked great. Sharp and clean.

Top notch

My father was a plumber and taught me to trust RIDGID. These dies live up to the name. They cut smooth threads on schedule 40 pipe. I threaded a dozen nipples and they all came out perfect. The case is sturdy and keeps the dies organized. I expect these to last a long time.
