I have cut the nut but there is little bit left over. I have many types of battery powered tools but not a grinder. There is no access to an electrical outlet. Any advice on removing the left over metal so I can separate the 2 pipes. If using a rotary tool, is there some kind of bit that can do the job. I am trying to avoid manual filing.

How about a chisel? If you don't have a chisel, you can make one with a file.

the range is limited. using a filer, filing back & forward will hit the floor that will lose momentum. tables would be a good idea but i don't have access to 2 tables and clamps because pushing force on the metal surface while filing is needed.


Why??????????

but there is a bit of the nut left. i assume that little piece of the nut holding on to the shaft of the bolt.

Home Depot, Ace Hardware, Amazon.com, perhaps the site listed?

Insert to drill, grind away.

I presume that by "nut" you mean bolt or screw.

Why not centre punch it and drill it out with one of your battery-powered drills?

If you drill to just a shallow depth with a bit almost the full diameter of the bolt shank, then you can use a small chisel to collapse the edges of the bolt shank inwards. This will shorten the shank and remove the extra bit that is holding the flange in place.

It's just like drilling out a rivet. Pick a drill the same size as the shaft, maybe a touch bigger. Center punch it first. The drill will slice the edges of the bolt/nut right off. If your drill takes a small nip out of the flange it's no big deal.

That appears to me to be a pipe and catalytic convertor .....Yes ?

Just give it a few whacks with a good hammer and it will loosen up the rust that is holding it together.

it is a catalytic converter connected to the front pipe. the nut fused so it had to be cut off. the other side is the bolt. thank you for everyone's reply.

hey Patch, i have never used a Carbide Burrs bit before. a long list of Carbide Burrs bits. which one do you suggest that can do the job?
