Use a bench grinder or abrasive pad to clean up the end of the bolt and use a wrench to back the nut off the bolt. here
After cutting the bolt, wait a few seconds before touching it as it will be extremely hot.
To do this, you’ll need a bench vise and an angle grinder with a metal cut-off wheel . Use a Sharpie pen to mark where you want to cut and use the vise to secure the head of the bolt. Screw a nut down to the base of the bolt before cutting it, this will aid in getting the threads lined up again after you cut it. With the angle grinder on, approach the bolt at a flat angle and cut right through.
An angle grinder is the best tool to use for trimming down exposed bolt ends. Here’s how to do it.
Always wear safety glasses when using an angle grinder and take note of where the guard on the grinder is facing to catch the sparks. Be aware of anything flammable on your workbench or in the immediate vicinity and remove them to prevent fires.
Remember to wear a face shield and safety goggles, though, as the process can be really dusty. And the flying debris can cause serious injury. Trust me when I say that grinding beats using a chisel and a hammer any time of the day. [links]
What is an angle grinder used for? The following list of angle grinder uses will definitely impress you.
Keep in mind that a professional tile saw is a better option for cutting in a straight line. Hence they are the preferred choice for construction work. But when you want to replace the old tiles, an angle grinder is what you need. here
Get a paint stripper wheel or a cleaning fleece that will quickly remove old paint and rust from metal without damaging the work surface. You can also use this to smoothen the rough surface and to remove the thermal bluing caused by welding or heat treatment. [links]
Are angle grinders dangerous? Angle grinders are powerful machines, and as you know, with great power comes a great risk of injury, especially that grinder discs spin at high speeds that can reach 10,000 to 11,000 RPM. One slip of a hand and you may lose a finger, arm, or leg. Scary, huh?
Hello! Amateur mechanic that normally settles for doing brake jobs and oil changes on my own and friend's cars. However, my sway bar link arm recently broke, I saw it was a simple "loosen two nuts, remove old arm, attach new one, tighten two nuts, enjoy working sway bar again". Well, after a couple hours, a can of rust buster, a 3 foot torque bar, and a blown up ratchet (thank god it was a Pittsburgh), I decided to take Harbor Freight up on their sale and got an angle grinder and a cutting disk. Found loads of things on cutting rusted bolts down but not much on trying to cut a nut rusted onto a bolt so bad that it might as well be welded on. Any advice on the best way to do this or is it even possible to do? Couple friends told me to take a torch to it but I don't have one readily available. Car is a 2007 Nissan Altima and, the way the suspension is designed where the link attaches, it looks like the only angle I'll have is coming in from the end of the bolt (I can try to find a pic if needed). Thank you! [links]

I have also used a reciprocating saw with metal blades that has worked well.
A Dremel will work, but will take forever. I would use an air-powered die grinder with a cutting wheel or an electric 4 1/2" angle grinder with a cutting wheel. I use both and they work well for cutting almost anything.
Anyone have experience with these?
It fit over the nut then screwed down and a wedge went into the nut and broke it. more
Re: best tool to cut rusted bolts/nuts
actually for $10-15 dollars a welding shop will torch the off in no time. i have used Sawsall with metal blade, grinder, etc. now i just take it down to Pat, and in 10 minutes everything is off. worth every cent, and no busted knuckles.
