Using a Bolt Cutter to Cut the Lock

Let’s Try an Angle Grinder

For using an angle grinder, you must ensure electricity first. If you are at home, you can simply plug in into your wall. However, you must purchase a battery-powered grinder to use outdoor.

As angle grinder produces small sparks while grinding, you must take some safety precautions. Cover your face and body entirely. Make sure a fire extinguisher is nearby for emergency situations.

Now, you will need vise-grips to lock your bike lock. Make sure the lock is firm and tight. With your non-dominant hand, hold the vise-grips to finally make a move.

The final moment has arrived. Take your angle grinder. Slowly press the disc towards the shackle. Give it a nice, thorough cut. You must be extremely meticulous while grinding or else, you might get yourself into a terrible accident.

Cutting with a Hacksaw

Just like the angle grinder we did, you will require vise-grips for the hacksaw technique too. Fasten the vise-grips sturdily with your lock. Now, hold it tightly so that the lock doesn’t move too much.

Make sure you wear gloves while you are breaking lock in this method. Now, get a propane torch near the shackle and burn it for 3 minutes. After the lock is red hot, turn off the torch and cut through the area with your hacksaw.

You will get best results in this way for metal locks.
