How to cut a "hardened" Master lock?

[30-30]

I had a key break off in a heavy duty Master lock on one of our storage containers at work. Any ideas for getting it off? Will good quality bolt cutters work, or am I looking at saws and torches?

Grinder with a cutoff blade will get it

Grinder or a torch! It would take some serious bolt cutter to get through that lock. Good luck!

I vote for a 12 gauge.

Sledgehammer and one or two good whacks. I lost the key to the lock on my boat trailer and I broke it with a regular claw hammer.

Depends on what Master lock you have, some look tough but don't have a hardened shackle. Is the key broke off flush with the key cylinder? Have another key for said lock?

Big hammer and a crowbar. Wedge in push down and a few good licks and it will break the little pin that goes in the notch of the hook part that's the weak link of locks.

All you need is a couple of wrenches





Well maybe not in your case, but it's still cool

This is what the lock looks like.

Thanks for the suggestions. I was really hoping that bolt cutters would work...

I don't think that will work with a "good" lock but neat trick if I need to break a cheap one off

Angle grinder will cut any lock it can get to....and a whole lot more.

One of my favorite tools....till the blades shatter on ya lol

I don't think there is a lock or cable out there that will stop this combination.
