There are some materials that are simply more difficult to manage than others. Rebar is one of those stubborn materials. Though special cutting tools may make cutting your rebar easier, they can also be pricey, have very few uses, and are often very difficult when it comes to mobility. You can however use your angle grinder to cut rebar no problem.

How to use an Angle Grinder

The first step to using an angle grinder is to choose the correct size for the job. A very small grinder that is used for simple tasks might not cut rebar effectively. You can also find very large grinders but in most cases a standard 4 inch to 4 ½ inch is going to be able to handle most jobs. The next thing to keep in mind is the quality of the angle grinder that you choose to purchase. Though very high quality grinders can be expensive, they are going to last far longer than a cheap model.

On top of all of that, you need to learn your angles. The angle of your grinder can make a huge difference in how well it cuts the material that you are cutting. With things like stone and ceramic for instance you need to may close attention to how you go about cutting to prevent major breakage.
