Why do cutting discs break, and how to avoid it?

Author: Enjoy 2025-07-05 7 min read

Many use cutting wheels for cutting a range of materials including metal, wood and plastic. But occasionally they do shatter and they can be dangerous when they do. But why do those cutting wheels explode, and how can we prevent that from happening? Let’s learn more about that.

The fundamentals of cut-off wheel failures

There are many causes of broken cutting discs. One of the main reasons is that it is not cutting with the right cut-off disc for the material being cut. For example, if you use a wood cutting disc for cutting the metal, there is potential for it to break due to the applied pressure as metal needs more force to cut through. Always make sure the aluminum cutting saw blade in use is the correct size, length and type.

A second cause of failed cutting wheel operation is worn or damaged disc. The cutting wheels may become dull and less effective over time. If you notice any cracks or specks on the disc then just replace it. A broken cutting disc can be potentially dangerous and might cause accidents.

Common mistakes contributing to the failure of a cutting disc

Incorrect cutting method One of the common mistakes that can lead to cutting disc failures is an incorrect cutting method. Naturally, you should always refer to the manufacturer's instructions for cutting discs to ensure they are used and positioned as the manufacturer advises. If there is too much pressure or the cut was not made at the correct angle, the disc will break.

It’s also a mistake not to have the proper tool. There is a large tendency to e.g. cut a cutting disc to break if you saw with it in material where it is either too small or too large. Be sure to always use the appropriate cutting disc for whatever you’re cutting, because you can never be too careful.
