Larger pairs of bolt cutters can cut through locks with a larger diameter.
If the lock isn’t attached to anything, secure it in locking pliers or a vise so it doesn’t move around when you try cutting it. Spin the handle on the vise to close it around the lock.
If you can’t cut through the lock yourself, ask a friend to help you close the bolt cutters. If the lock is made of hardened steel, bolt cutters may not work. Bolt cutters work best on padlocks or chained bike locks.
Angle grinders work best on padlocks or bike locks. If you’re working at home, use an angle grinder that plugs into the wall. If you need to work somewhere without electricity or an outlet, buy a battery-powered grinder.
Make sure there are no flammable objects near you or in the room since a spark could ignite them. Keep a fire extinguisher nearby just in case.
Vise-grips can be purchased at your local hardware store. If you’re working in a shop, clamp the lock inside of a vise instead.
The lock may be hot near the area you cut. Use gloves to handle it or let it cool down first.
Don’t use your bare hands to hold the lock since you could burn yourself.
Find an area on the shackle that you can easily maneuver a saw around. Work in a well-ventilated area away from flammable materials. Keep a fire extinguisher nearby in case there’s an accident.
The heat softens the metal and helps the saw teeth stay in place as you try to cut the lock. Hacksaws work best on metal locks.
