These pipe threading dies are made from high-speed steel, delivering the toughness needed for repeated cutting without losing edge quality. The sharp cutting edges create smooth, uniform threads that improve pipe sealing and connection reliability.

They are designed for right-handed threading and cover NPT pipe sizes from 1 inch to 2 inches. Compatible with RIDGID universal die heads and split-type machines like 504A, 711, 713, 811A, 815A, 816, 817, and 842, they fit easily into existing setups without extra adjustments.

Installation is simple. Follow the clearly marked numbers and insert the dies in order. This reduces setup errors and gets you back to work faster, whether you're on-site or in the workshop.

Compared to generic dies, these maintain cutting accuracy longer and handle demanding workloads without frequent replacement, helping you keep projects moving efficiently.
