What is the RT2L Rotary Thread file Used For?

The RT2L Rotary Thread file is one of Rotary Thread’s universal thread files that you can use to restore any kind of threaded material.

You can use an RT2L Rotary Thread file for restoring loose inner and outer threads.

It is the only thread repair tool today that offers flexibility and versatility when it comes to thread restoration, making it the go-to thread repair tool for in-home projects, automotive, farm & ranch, and industrial needs.

You don’t even need to have much experience to effectively use this tool. We specifically designed it to be a plug-and-play tool that you attach to your die grinder for immediate thread restoration.

The user-friendly design enables users to restore fitters, cylinders, pistons, rods, bolts, and even the deepest threads in nuts with ease.

No need to spend hours fixing damaged threads, the RT2L makes everything simple and quick with its universal pitch design.

Fix Any Threaded Tool or Material!

The RT2L Rotary Thread file was designed to restore threads made out of Metals, Hardened Metals, Ceramics, Glass, and Plastics.

We say you can fix “Any” threaded tool because we designed all Rotary Thread files to come with a universal 60-degree “V” angle that makes it compatible with Inch, Metric, Pipe, Male, and Female threads.

It eliminates the need for measuring the pitch and diameter and helps you get precise clean threads whenever you’re restoring damaged threads.

With this tool in your toolbox, you will definitely see no need for expensive replacement parts and repairs! You can fix any loose thread yourself in just a matter of seconds.

Quick Storage & Easy Maintenance

The RT2L Rotary Thread file is a highly durable tool that you don’t need to spend too much time on when it comes to maintenance. It also comes in a compact design that makes it easy to store in a small toolbox or drawer.

For best performance and a longer lifespan, we recommend using the tool with tapping oil and light pressure when restoring damaged threads.

It is also recommended to clean the tool with a non-flammable paint thinner after every use.

    Used just yesterday after receiving it a couple weeks ago. Saved the threads on a unreplaceable track pad. Must have tool for your rethreading kit.

    This makes quick work of fixing bent threads using a rotary tool.

    Just the thing for fine thread rejuvenation work but be patient, cautious, and not to get too aggressive. I needed to repair a fine set of threads on a wheel hub for an antique car and when the job was done the cap screwed on smoothly as when it was new. Thanks.

    Works beautifully. I knew it would. It’s so simple. It’s 60°. I had a fitting that wouldn’t screw in to a valve. Instead of trying to figure out the thread size, ordering a tap to fix the thread and being down for a couple of days, I used this little thing. After grinding about 6 teeth deep for a couple of minutes, I tried the fitting again. Spun right in without effort. I was done in about three minutes. This little bit saved thousands of $$$. All it takes is a small rottary tool, a steady hand and half a brain.

    I’m a mechanic. Damaged threads are just part of the job sometimes. The case that brought me in contact with this tool was a spindle on the rear end of a Dana 80 truck axle. It would have required a $200 3″ threading die. I decided to try this tool. I took something that looked beyond repair and transformed it to the point where the large lock nut spun on by hand.It takes some skill. It’s not a toilet plunger. You need to have a steady hand and a good Dremel tool but the payoff is quite impressive. It’s a tool anyone who works on anything threaded should have. It saved my butt and a buttload of money as well.

    Although I was shocked by how small it is – it saved a damaged 3/4″ threaded rod I had already welded to a bracket. I used a Dremel and magnification and was able within a few minutes to get the nut to travel the full length of the rod. ONE LIMITATION is this works best where you can get the tool perpendicular to the threads being repaired. Even using a Dremel extension I had to work at a slight angle 6″ from the end of the rod which wasn’t a problem due to the large threads I was fixing but it could be an issue on finer threads.

    this file worked amazingly well on a decades old floor drain that was rusted.. I recommend it to anyone with any thread problems..

    It works really well! I just needed to practice a bit. Recommend buying both sizes. Do keep in in a safe place. My smaller one got a little bent. My own fault really.

    Got me out of a few binds. Get both sizes.

    This little tool is the bomb. Used it to fix female thread that was crossed threaded in my RV’s water heater drain plug. Now it’s back to normal thanks to this bit. Highly recommend this to get yourself out of this kind of jam.

    Repaired very fine threads on an expensive engine part with ease. It was a size I would never have used again if I even wanted to spend the $150+ on a die in that size

    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.

    This product saved me from having to buy a $200 part for my car’s emission system. Follow the directions, work slowly and you will get clean usable threads.

    Easier to use than chasing threads with a file to get rid of paint and nicks on threads
