Restore any threaded item in your home or workshop in under a minute with the RT2 Rotary Thread file! The RT2 is one of Rotary Thread’s universal thread files that you can use to restore both external and internal threads.

The RT2 was designed by industry professionals for easy home use and heavy-duty industrial jobs. Whether you’re experienced or not, you can use the RT2 to restore threaded Metals, Hardened Metals, Ceramics, Glass, and Plastics with Inch, Metric, Pipe threads.

What is the RT2 Rotary Thread File Used For?

The RT2 Rotary Thread File is a universal thread repair tool designed by industry professionals to make it quick and easy for anyone, even beginners, to perform restoration and repair jobs at home or at work.

We have engineered this tool to be the only tool you’ll need for restoring threads in any kind of furniture, appliance, or heavy-duty machinery. It completely eliminated the need for traditional taps and dies that take hours to use.

You can use the RT2 Rotary Thread file for restoring loose Inch, Metric, Pipe, internal, and external threads because of its universal 60-degree “V” angle design.

The RT2 is the only tool you’ll need for quick threading restoration for your in-home projects, automotive, farm & ranch, and industrial jobs.

All you need is a die grinder, a vise, and a Rotary Thread file to start restoring your damaged threads.

Simply guide the RT2 Rotary Thread file along the old threads and work your way towards the damaged threads and you’ll instantly see getting clean and defined threads.

Fix Any Threaded Tool or Material!

Unlike other thread repair tools, the RT2 Rotary Thread is made with highly durable steel that can help you restore threads made out of Metals, Hardened Metals, Ceramics, Glass, and Plastics.

Another benefit that comes with its universal 60-degree “V” angle is that you no longer need to measure the pitch and diameter of the threads you plan to restore. This is why working with an RT2 Rotary Thread file only takes seconds in comparison to traditional taps and dies that can take you about an hour just to restore one threaded part.

With the RT2, you can fix damaged threads yourself and avoid spending on expensive repairs and replacement parts!

Quick Storage & Easy Maintenance

The RT2 Rotary Thread File is a low-maintenance tool that can last you years of daily use. It is made with high-quality steel and comes in a compact design that makes it easy to store away in your toolbox.

For best use and long life, we recommend you use tapping oil and add light pressure to the tool during use. We also suggest cleaning the tool with non-flammable paint thinner after restoring threads.

Available Replacement Parts

Whether you’re looking for a replacement part or an extra piece to keep on your toolbox, you can always rest easy knowing that all Rotary Thread tools are available online. We offer files, grooves, glands, mandrels, and collets by the piece on our website.

    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,

    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.

    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.

    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.

    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!

    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.

    I removed the grab rails off my sailboat to remove layers of varnish and then apply teak oil before re-installing. The nature of these grab rails are that they have 7 stud bolts on each of the two rails and they firmly attach the rails to the top of the cabin – The studs pass thru drilled holes in the Fiberglas and then washer, lock washer and nut hold the rails firmly on top of the cabin. The bolt head end of the stud is not visible – It is inside the top of the rail and wood plugs contoured to the top of the rail hide the bolt heads. These studs should never have to be removed from inside the rail and to do is a chore since the plug would have to be drilled out and a new one installed and contouredmto the rail. Initially, when I removed the nuts from the studs inside the cabin, one of the nuts was had to unthread from the stud and the stud started to rotate within the rail. So, I had to use pliers to hold the stud tight and another set of pliers to unthread the nut. When it was time to re-install the nut, I could not thread it onto the stud. My pliers had ruined the lower threads.I was considering using a diamond cutoff wheel on my Drexel to remove the lower threads but that would leave few threads available to re-install the nut and besides The nut was had to unthread it initially, so I would still be face with that problem as well.I then discovered the EZThread 382 searching the web and Amazon for solutions either by buying a different type of fastener to clamp to the existing threads but then I came across this tool to repair existing threads.The 382 mini-grinder tool was easy to use. It just about 1-2 minutes of use, I was able to get the nut back on. But other threads made it hard to completely re-install the washers and nut, so I tweaked addl threads and kept testing how easy it was to completely install the nut. After only another few minutes of tweaking the threads, the nut washers and nut were able to be re-installed easily. Since I was now able to rethread the nut all the way up to the inside cabin top, the friction fit at the bolt head kept the stud from rotating within the rail and I was able to torque the nut fine. So, this tool not only repaired the initial threads to get the nut on but tweaking the rest of the threads enabled me to utilize the stud, get a tight fit, without having to replace the stud which would have been a much longer repair and would have required labor to replace and contour a new plug on the outside of the rail.This is a great tool ! I am telling all my friends about it !
