I'm not sure if this is a Steve's first or not, but there's a trailer hitch welded to the back of my car. That's right, a trailer hitch. Its welded to the frame and also the panel underneath the back bumper.

I've been grinding on them for two days and have not had much luck removing the hitch or cutting through any of the welds. Anyone have any ideas for removing the welds that hold this thing on? I've looked at the spot weld removing bits, but these aren't spot welds, they're beads along the steel frame of the hitch. I'm not the master metal worker, so any ideas would definitely be appreciated.

Cutting torch or plasma cutter.

I'm assuming your not using a dremel are you? It sounds like it by stating 2 days.

Sawsalls work good for hard to reach areas, a cutoff tool works good too. Harbor frieght right angle grinder with some thing wheels also come in handy.

If you have a compressor, then a die grinder using cutoff wheels.
Just be sure and wear eye protection as those cutoff wheel are verry brittle and will break or shatter.
Something like this:

You could also do it with a Dremel tool and the little cutoff disks.

Thanks y'all. I've been working at it with a Harbor Freight angle grinder, but its just not going very fast. Whoever welded this thing on, was serious! I was just curious if there was something faster and better. I appreciate the ideas.

An angle grinder should zip that thing right off there in quite a hurry. It's a 4" grinder right? You're grinding on the welds correct? If so, I don't know what else to tell ya. Maybe your have a sanding disc and not a grinding disc on there? It should be like a hard, very course stone almost.

An angle grinder with a cutoff wheel ( should be 1/8"thick) should cut through the weld.

Razor Blade

If you have a 4" angle grinder try using a "RAZOR Blade" sold at most hardware stores.They are usually 6" but you can remove the shield.Be carefull because they will cut anything including skin.They will slice right through 1/4" plate.

I use a plasma but a angle grinder works well. Use the edge of the wheel concentrated at the bead just away from the frame. JR

You are going slow because you are using a grinding disc.

Switch to a cutting disc. Be careful, they like to kick back when they bind.

FYI.. you can get a 4 1/2 " cutting disc on your 4" grinder, it will fit in the guard ( barely ) just fine. Just center up the disc, then tighten down the collar.

NEVER RUN A GRINDER WITHOUT THE GUARD.
