Why it works

All inch, metric, and pipe threads have the same 60 degree “V” angle.
Rotary Thread’s patented tool profile has the same angle, working one thread at a time. Forget about measuring the thread pitch. This allows the tool to quickly work on any project, inside or outside threads.

Testimonials

From simple garage DIY projects to industrial grunt work – here’s what our customer’s say about our products.

Saves me 5k. I cleaned up thread on spindle of semitruck axle thread. It was like 30% missing this thing cut right through. Was able to change bearings and seal nuts went on amazingly.

It's very rare these days that things actually work. Saved me $985! We have a firetruck and one of the hose reels threads had corroded to the point of no return. I gave this thing a try and i actually still cant believe it worked!

This thing is a must have. Saved me from having to buy a 300$ tap for an M27 thread on a pair of stainless long tube headers. Cleaned up the threads well and allowed me to install the correct fitting.

Mangled the threads on a one inch axle removing some components with a hydraulic press. This file took some time, but allowed me to fix the threads to point.I can thread axle nuts on by hand.
