What is Rotary Thread? 

Rotary Thread is a rotary tool attachment that brings new life to old, worn, and damaged threads. Rotary Thread tools and repair kits are versatile thread restoration solutions, which are excellent additions to any toolbox. 

There’s no shortage of thread repair tools on the market. The most common ones include— 

Then there’s Rotary Thread. 

It’s obvious that you’ve got plenty of choices when it comes to thread repair and restoration tools—so much so that choosing the right tool for the job can be quite confusing.  

Which tool makes the most practical sense?  

Which tool best fits the job?  

Which tool gets you the best results?  

Spoiler alert—it’s Rotary Thread. 

What Sets Rotary Thread Apart? 

If you’re a professional mechanic or technician, a home improvement buff, or a DIY enthusiast, you know just how commonplace threads actually are. Threads are ubiquitous—they are everywhere. And yet they’re not all the same.  

Threads vary by quite a bit. You have internal and external threads, along with the most common inch, metric, pipe, ACME, square, and buttress types of threads.  

Fixing any single thread using traditional thread repair tools would require you to carefully match the right tools to the exact measurements of the thread you’re working on. This is true for thread files, taps and dies, and threaded inserts, among others.  

But NOT for Rotary Thread

A genuine gamechanger in thread repair, Rotary Thread is the one and arguably the only thread repair and restoration solution on the market that works on both internal and external threads, as well as on ALL of the most common inch, metric, pipe, ACME, square, and buttress types of threads. 

Rotary Thread’s 60-Degree V-Angle Technology

All threads share the same 60-degree V-angle in their fundamental design—so does Rotary Thread. Rotary Thread’s proprietary 60-Degree V-Angle Technology is what ultimately makes it capable of undertaking any thread repair and restoration project.  

The particular thread measurement, otherwise referred to as thread pitch, is of little-to-no consequence, as Rotary Thread travels across and creates new threads off the original 60-degree V-shaped profile of worn and damaged threads.

What thread files, taps and dies, and threaded inserts do in an hour—Rotary Thread does better in minutes!
