/diy/ - Do It Yourself

Depends how sturdy it is.
Smaller ones you can just break open by doing something like this. I used a couple claw hammers on a bigger one once but it was a really shitty chinese lock with a pot metal shackle so I don't know if it scales up very well most of the time.

If it's a big lock, you probably want an angle grinder instead of a dremel. They're ridiculously handy things, just never get too comfortable around it.
