How To Cut Off A Lock- Step By Step Guide

There is more than one correct way of cutting off a lock. You can find yourself in many situations when you have only limited resources. So to help you out in all those times, we are going to discuss some of the most trusted and verified ways of cutting off a lock. 

Method 1: Cutting With Bolt Cutters

Method 2: Grinding

Step 1

You might have got an idea about this method from its name. In this method, we will cut off a lock with the help of an angle grinder. First of all, if you do not have an angle grinder, arrange one. Now for those of you who are not familiar with what an angle grinder is, it is a simple device available at any hardware store. It has a disc in place of simple blades. It is used to cut metals as well as solid materials like tiles.

It is vital to know the appropriate size of the tool as per your requirement. In this case, you should choose an angle grinder of about 60 grit disc, which means approximately 3⁄64 inch or 1.2 mm thick. 

There are many brands and models of angle grinders available in the market. However, you must choose the one which suits your requirements. For example, if you will work at your own home or somewhere with uninterrupted electricity, buy a corded angle grinder. But, if you are going to work somewhere without an electric outlet, it will be better to buy a cordless angle grinder.  

Step 2

Now before moving forward, you must remember that while working with power tools, safety is of utmost importance. So, do not forget to wear gloves and a face cover. It will protect you from the sparks. If you do not get a proper shield or work suit, wear a long-sleeved shirt and pants.

Also, ensure that you are working in a safe environment. There should not be any flammable items nearby. To be extra sure, keep a fire extinguisher handy. 

Step 3

Now that you are all safe and secure, it is time to start working. Secure the bottom of the lock with vise-grips. You should allow the vise grips to be opened about the same width as the lock. Once the lock is steady and locked on the vise grips, you can move on to the next step.

Step 4

Now, after securing the lock on the vise grips firmly, it is time to start cutting. So, take the angle grinder and cut through the top of the lock’s shackle. You need to switch on the grinder and press it slowly to Turn on the angle grinder and slowly press the disc on the shackle. You will experience sparks coming out of the lock while cutting. Do not panic. It is normal. Keep cutting the lock and apply a firm pressure overall. Once you are all done, power the grinder off and remove the lock. However, remember that the lock might be hot at the spot where you have cut it. So, you should wear gloves and be careful.

Method 3: Heat And A Hacksaw

Step 1

In this method, we will need two things: a hacksaw and a propane torch. So, let us start. First of all, secure the lock in a steady position with the help of vise grips. If the lock is attached to any item, make sure to tilt it away from that. Remember that we will use an actual torch and a hacksaw, so it is advisable not to hold the lock with your hands as you might get hurt.

Step 2

Now, you need a propane torch. Ignite the torch and hold it near the shackle of the lock for about 3 minutes. Be cautious while working with it. It can be pretty dangerous, so it is advisable to keep a fire extinguisher nearby. 

Step 3

Now leave the lock and let it cool for 3-5 minutes. Do not use any cooling agent or even water to lower the temperature of the lock. 

Step 4

Once the lock is not very hot, use the saw to cut the area you had heated. You should use a fine-toothed hacksaw for this purpose. The heat has a softening effect on the metal, and it becomes easy to cut the lock with the hacksaw after that.
