Solary Magnetic Induction Heater Tool - 1200W 110V Hand-held Electromagnetic Induction Heater Kit with 12 Coils, Rusty Bolt Removal Tool

It takes much longer to heat up nuts than advertised but it works great. What is good if you use torch you are heating the stud and nut because you don't have proper heat control but this machine only heats the nut and therefore there is no chance of snapping the stud and the nut comes right off. Great tool for doing automotive exhaust where studs and nuts are badly rusted. I wish I had this tool years ago. Easy to use and saves time. Great tool.

Works great, wish I would have bought one years ago. Well worth the money.

I have a backhoe and have to remove the back tires. attempts were made using impact driver, 4-foot power bar, and a torque multiplier which broke an extension and a 1 &1/8-inch socket, of course. both were from China. I purchased the heat induction tool, and the lug nuts were like butter coming off with a couple of minutes heating each nut. This tool is fantastic. I have an oxy acetylene torch, but it takes forever to heat lug nuts this large. If you work on large trucks or any automotive equipment this tool is a must have.

The heater arrived in a timely manner, but the actual unit itself was used. I emailed the company, and they responded quite quickly. Upon sharing a couple pictures of what had been sent, they promptly sent out a replacement. This thing works great. Its maiden voyage was on an O2 sensor, and the sensor came out without any issues at all. The internal cooling fan comes on when you plug it in and the induction is initiated by a momentary thumb switch. My suggestion is to let the unit fan run for a time once you've heated up your intended target. This will allow the unit to completely cool (internally), and most likely extend the life of the tool.

I bought this to help remove rear brake caliper brackets on a 20 year old car in the rust belt. Those bolts had never been loosened on that car and were rather rusted/fused. For context, those bolts are M10 x 30mm that require a 15mm wrench, so a "medium sized" bolt by vehicle standards. At first, I tried heating just the head of the bolt, thinking the heat would travel down the threads, like others who have commented on success with just heating heads of body frame mount bolts which are clearly much bigger. Should be no problem, right? Well...no success, even after 4 consistent minutes of heating the bolt (at which point the unit went into "overheat protection" mode). That's also how I discovered this unit might lacks the power to make the bolt glow red hot like you see in videos. After some bending of the supplied coils, I then was able to heat the part of the hub where the bolt was threaded into for a couple of minutes, and THAT is what loosened the bolt enough. Now....in my case, the bolt was not "magically" easy to remove either. It still took nearly 100 lb/ft of force to bust the hex head bolt loose. Now....the hub body and bolt were absolutely hot as you can imagine, but definitely not glowing at all. Overall, I think this item was well worth the money. It has about the same heating power as a propane torch. If you're needing more heat (like MAPP gas torch level of power that will make even you engine block glow) then this is not the unit for you, and you'll likely need to go for the version you see on Amazon that costs twice as much and has a big bump up in wattage power. For most situations requiring focused heat, I think this tool will be sufficient, especially if you are able to heat the nut or threaded part the bolt, rather than the bolt head

I purchased to help with replacing F350 body mounts. Those bolts are long, covered in thread lock, and notorious for spinning the captured nut. I used this on 4 of the 8 bolts, and I would say that it definitely made them easier to unscrew. I also used it to heat up O2 sensor bungs on a Jeep that another person couldn't get to budge. Heated them up, shock quenched with water, and they broke loose. Definitely worth the money for those two jobs alone. It is long, but I bent the copper coils in order to get over the bolt heads and O2 sensors. The cooling fan comes on immediately, and is as loud as a hair dryer. I let it continue to run a few minutes after using to allow the internal components to cool down before unplugging.

Works as advertised have used it a dozen times without issue .

Ever wish to use a torch INSIDE a vehicle to get a bolt loose? This gets things cherry red hot without the open flame. Sometimes it's just easier do bust this tool out than it is to drag the torch out. The induction heads do wear out but replacements are affordable. It all depends on how you use and that the tool. One of those tools you wish you had if you don't.
