Steps to Follow to cut off bolt: 

Below I am going to describe the steps that you will have to follow to cut off the bolt with an angle grinder: 

1st Phase:

First of all, you will have to create a line on the screw with a pen or marker where you want to cut. To ensure accuracy, you must check the screw with a yardstick or tape measure. The entire size must match the right dimensions. It will help you make the precise and right cut using an angle grinder.

2nd Phase: 

After that, you will have to tighten two nuts completely to the bolt’s bottom. The nuts must be twisted and placed closely together. To make it simple to fasten the screw to the clamp, this step is essential and very helpful to make it a quick task. 

As you slice the screw to the required size, the nuts will also help you line up the holes. If you don’t place the nuts first, the screws can get broken. This will make it harder to place the nuts in their position after you break the screw.

3rd Phase: 

The next stage is to firmly tighten the nut on the clamps after you have finished that process of tightening the nuts. The screw must be in the right place that is both reachable and suitable for cutting with the grinder. 

To prevent the bolt from sliding after it touches the surface with the cutter, it must be firmly fastened. This will prevent any sort of danger or risk.

4th Phase: 

You should put on protective goggles to cover your eyes before starting the cutting with an angle grinder. It is also suggested to wear earplugs because the grinder has a loud operating noise. This could harm your hearing, so it is better to protect your ears to minimize any kind of risk. 

As some people did not use safety equipment, there have been severe incidents that sent individuals to the hospital. So, being secure is preferable to being injured.

5th Phase: 

Now you will have to switch on your angle grinder slowly after fitting it with the proper sharp edge. With less effort, you can simply cut the nut. The final point you need to do is lift a sharp object with pressure. 

You can use a level inclination and maintain the boundary line you have drawn. You are now prepared to use a steady and delicate stroke to slice through the screw. Once more, you must avoid using any strain or power.


Additionally, when you perform the cut, you will have to ensure that the blades are pointed away from your body. Also, make sure that nothing will be damaged by it when it will come to you. 

After you’ve sliced the screw, you will have to avoid grabbing it as it can become hot when touched. 

Instead, you should let it cool down before holding it to prevent any tiny particles from spreading.

6th Phase: 

Now you will move towards the deburring. It is the process of removing sharp corners from a nut that has been cut. You will polish the bolt using an adhesive cloth until there are no rough edges. It is necessary because they could cut your body.

7th Phase: 

It is time to reform the threads so that the nut can be used. Before slicing the nut, you must first loosen the two nuts you attached to it.

When you face resistance at the start, you must detach the nuts. To remove the nuts from the screw easily, you will have to use a screwdriver.
