Rotary Thread File! The RT2L Rotary Thread File is the only tool you will need to effectively restore damaged threads within seconds!

The RT2L was designed by industry professionals to make it possible for beginners and professionals to finish thread restoration jobs for Inch, Metric, Pipe, Male, and Female Threads made out of Metals, Hardened Metals, Ceramics, Glass, and Plastics with precision and speed.

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.

    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.

    It’s very rare these days that things actually work, and this thing worked. Saved me $985!. We have a firetruck and one of the hose reels threads had corroded to the point of no return. The replacement cost was extremely expensive as the thread is attached to one piece and can not be replaced. I gave this thing a try as a hail-mary and it actually worked. Half of the threads were on the backside that I couldn’t see so I just followed the front threads and prayed that i wouldn’t jump over a thread. Followed it all the way back around and kept going. Used a little Brakleen to clean off the grit and the coupler fit right on first time around. I still cant believe it.

    Concept of tool really good when used in good hands however the shank of tool is too short, it would only reach part way into threaded bore in my case and chuck of rotating tool got in the way. It will be a usefull addition to my rethreading repertoire but next job not this one.

    Worked great to restore threads I buggered up in a water filtration tank . 2 1/4 straight Pipe Thread… used dremel and a small cordless drill. Both worked well. Used Boeing drill Lube because completely non toxic.. get right RPM , start in good tread and keep moving around over damaged area in a smooth and even motion.. You can feel the damaged spots.. don’t try to sit in one spot to remove damage… keep trying fit so as not to remove to much material..

    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.

    I purchased the smallest rethreader at 3/8″ diameter to help a neighbor friend who had badly cross threaded a unicycle set of pedals. The threads were about 13 mm and both right hand and left hand threads, so it would be too expensive to purchase both taps for the cranks. My neighbor replaced the cross threaded pedals so I “only” needed to clear the female threads. I used tap oil and the small tool in a dremel tool. I held the Unicycle wheel in my bench vice to keep the cranks stable. I used two fingers on the cranks for fine movement of the tool tip and my other hand held the back of the Dremel to keep it in proper alignment with the axis of the shaft. At first I was only able to hand thread about 1/4 of a revolution. I started working near the inlet of the threads with the tool. I was able to slowly get my hand to thread a few threads of the pedal shaft into the crank. I then started working from those good threads deeper into the crank. I would remove the pedal, clean the threads of debris, and see how far I was able to hand thread the pedal into the crank. I was able to keep moving it a few revolutions each time. Reoiled each time til I was about 4 revolutions from totally threading the pedal into the crank. I then gently used a wrench and worked the shaft gently around and back and forth as it rolled more threads clearing them. Not forcing the wrench too much was key as well as working back and forth gently threading the pedal into the crank until it was totally in. I removed the pelal and used medium blue thread locker and that side was done. The other side with left hand threads on the left pedal was worse and I could only hand thread about 1/8 of a revolution by hand. Started working again from the thread inlet gently clearing threads and hand threading the pedal into the crank making darn sure it was straight and true. This time, after clearing about half of the length I started using the wrench to help roll the right threads. Working back and forth and slowly and gently moving the shaft into the threads. Never forcing excessively. It went faster this way and I needed to remove less material with the tool this way. This tool is awesome on female threads that are buggered up. Needs a steady hand and work slowly removing as little material as possible and constantly testing how it is going. WIth a deeply cross threaded hole, this was the acid test of the tool and it passed with flying colors. Well worth the price and much less than replacing the cranks or purchasing two expensive taps. This tool is a keeper as I work on classic cars for a hobby and buggered up threads are common.

    I know this is a 1/8″ shaft bit, but I would rather use it in a drill, than a high speed rotary tool. If you had a variable speed tool, and ran it slow, it would probably be fine.What this does, is repairs damaged internal threads by use of a tiny grinding wheel with a V profile to match standard thread angles. It is not for cutting new threads, but fixing threads that are damaged. It works really well with galled threads, getting out the burrs that are all but welded in the threads.Go slow, and gentle, too high an RPM and it wants to chatter, and will not result in as clean of a repair.In my opinion, it is not meant for routine thread chasing, but rather as a rescue tool to clean out threads of things too hard to cut with a tap, or for something larger than you have a tap for. The bigger the diameter of the threads, the easier it is to do a good job. I had a choice to either replace a $30 spindle nut, buy a tap that size for $40, or clean up the threads with this. I took my time, and it turned out really well, and paid for itself in one use.

    If you have to repair threads, this is the tool you need, my only suggestion is order the larger one, also do not add pressure to the tool lay it in the damaged threads lightly run along threads,

    by Kathie C

    I bought this to clean up the threads on a part where the threads were distorted by welding. This tool cleaned them up nicely in a matter of minutes.I also used it to clean up the rusty threads on our main drain clean-out fitting which was pretty messed up after nearly fifty years. Fifteen minutes later the threads on the drain and cap were cleaned up and the cap securely screwed on.I would suggest when working on heavily damaged threads that you stop occasionally to flush the rust or metal particles out of the threads. And no matter what, flush them out when you are done.

    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.

    Bought this to give it a try and never got around to using it yet….. but I feel it’s a great product worth the money!

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

    by john dragon

    This little Rotary file does what they say it will do, but controlling the depth of cut will take a lot of practice.

    by Dale Hauck

    I bought it to use in my shop in place of a thread file. It’s smaller than I expected but that’s a good thing. Has been useful and effective.

  15. 97

    by Aaron Patterson

    The result isn’t as pretty as using a tap or die to repair threads but it works surprisingly well and is much less expensive than buying costly tools you will probably never use again.

  16. 97

    It fix any bad thread. Highly recommended. Easy to use.

  17. 97

    by Bruce H.

    While I didn’t use this exact thread repair item (I found one at the local auto parts store before this one got here) I filed both internal and external threads. The one I got at the auto parts store is the same as the one I ordered from Amazon. (kept both of them) These were 22mm left hand wheel studs and nuts, didn’t know this was possible. Worked like a charm!

    I purchased this tool after watching a review of a similar product on YouTube. This one is very similar if not the exact product. Works great with a high rpm impact drill. Also it does take a little getting use to at first, my suggestion is lock down whatever your working on and use two hands to control the direction of the drill as well as the recoil of the spinning bit. Also go with the direction of the drill while using. LIFE SAVER!!!

    I have to say, I was skeptical but this tool really got me out of a bind! I was rebuilding a rearend on a car and somewhere along the line the threads by the hubs were damaged. I could not get the nut to start and it was clear to see the malformed threads. After going over the threads a few times with this bit in a Dremel, the nut went right on. Saved me a ton of rework and a trip to the machine shop – or having to purchase a massive die. The price is a no-brainer, I highly recommend.

    I bought this to repair the socket for the ride guides on my boat trailer. The sockets are 1.25 in pipe couplers welded to the trailer, and the threads rust over time. This tool worked great!

    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 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.

    Loved this tool. I needed to fix the threads on an outdoor faucet and could find nothing except an expensive custom die or even more expensive universal thread restorer. It took less than five minutes from the time I started until I had the hose screwing on smoothly. Definitely stays in my toolbox!

    by Joe S.

    I’m not sure this product really “repaired” the threads. I had some threads on an M12x1.0 that were smashed in a small area that made it difficult to thread a nut. This tool is just a grinder and you need to be cautious about grinding too much. While it worked in that I could thread the nut on it was mostly due to the fact that this basically removed the threads in the spot entirely. If you aren’t careful you could potentially cross cut the threads.I think this may work better on larger thread pitches like 1.25+ but on fine threads like 1.0 its more difficult.The product “worked” but for the money a die or chaser still works better.

    Chasing fine threads with a dremel tool requires a steady hand or you will ruin the part.V cutter is hard to hold steady and will jump around. Tool works ok but you will need a v file to completeThe job

    After watching the short video I was confident the rotary tool would fix any damaged threads. I was mistaken. I purchased the rotary tool to hopefully restore some rocker arm stud threads that were damaged. Sadly it did not work at all. Maybe the threads were too far gone for repair. Luckily I was able to replace the studs with new ones.

    Used to restore threads on some coilover bodies. Worked great. Much better than buying a large expensive thread chaser if all you have are a couple damaged threads.For external threads, a thread restorer file may work a bit better/faster. But internal threads is where this product shines.Saved me a bunch of money, 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.
