🔧 What Is a Saver Sub?

A saver sub (also called a sub saver) is a sacrificial wear component that threads between the drive chuck and the drill pipe. It protects the drive chuck threads from wear during normal drilling operations. Always replace your saver sub when changing drill pipe — a worn saver sub will accelerate wear on your drive chuck and can cause costly damage. Saver subs should be checked regularly and replaced as needed.

❓ Not Sure Which Pipe to Order?

Contact us with your rig make, model, series, and serial number and we’ll confirm the correct thread and OD before you order. Ordering the wrong thread can result in damaged connections and downtime.
