This is not wise and I urge you not to take the above advice.
You want the Abus 83CS/55, or, if you're made of money, the Assa Abloy Enforcer 342. Jesus, folks, you can drill through that cheap-ass padlock in like 30 seconds. At least get a better shackle guard and a protected keyway. Definitely something you can't open with a hammer
