3 Causes of Diamond Blade Breakage

When it comes to getting the most use from your diamond blades, it can be challenging for some. Throwing segments or breaking blades can be not only frustrating, but also unsafe. What can you do to minimize the chances of diamond blade breakage or throwing segments? In this article we will look at three ways to reduce the chance of breaking your diamond blades.

While there are many things that can cause a diamond blade to break. Taking the proper care to use the correct blade, the right way, in the manner it was intended can reduce the probability of breaking a blade or losing segments. However, there are a number of specific ways a blade can be used “improperly”. And knowing what a blade was “intended” to be used for is not as easy at it may seem on the surface. Finally, choosing the “correct” blade to use takes some sizing up since many blades can be used for multiple purposes.

Blade Heating Up

One of the common reasons diamond blades break is that they get too hot. This can wreak havoc on the core, the matrix, and the segments. And even though there are some blades that are constructed more durably, every blade has a tolerance for heat. In fact, as we briefly look at some of the specific causes, you will notice that keeping blades in the proper temperature range involves much more than just using a high quality blade.

No matter which kind of blade you are using make sure that you are using it correctly. Having it tightened properly and completely perpendicular to the surface of the material you are cutting will reduce the chances of the blade overheating.

Dry Blades

Diamond blades that are made to be used in a dry environment (dry blades) need to be used in a certain manner. This is so that they do not become over heated. Dry diamond blades are cooled by air. Therefore, it is important to make sure that the proper amount of air can circulate around the segments and the blade. In fact, some blades should be operated in such a way that air can flow through the blade. Hear are some ways you can make sure you are allowing enough air circulation through and around your dry diamond blades.

First, be sure that you are using the proper blade for the material that you are cutting. Second, be sure that you use a shallow cutting method to make your cuts. Trying to cut too deep can put an additional load on the blade and cause it to overheat. Third, use your dry blade intermittently. This will allow the blade to cool down and not become overheated. Finally, do not overuse a diamond blade. Check your blades regularly and do not use a blade that is damaged or that shows signs thereof.

Wet Blades

Just as dry diamond blades need the proper use and maintenance, wet diamond blades also need to be used in a particular manner. Wet blades need to be cooled too. However, they are cooled using water rather than air. So be sure that you are supplying a sufficient amount of water to keep your blade operating at the proper temperature. Additionally, be sure that you are supplying water to both sides of the blade. This will help the blade temperature remain uniform.

Machine Condition

Although keeping your diamond blade cool is a great way to prevent blade breakage, there are other ways to protect your diamond blade from overheating. Additionally, you can protect your diamond blades from breaking by keeping your machines in top working order and well maintained. The following table shows some specific problems that can cause segment issues and/or blade breakage. It also lists what you can do to prevent or reduce the occurrences.

Another potential cause is the material is not secured properly during the cut. This can cause the blade to twist in the cut. So make sure that the material is firmly held in place while cutting. Additionally, be sure to provide an ample amount of water to both sides of the blade.

Problem Suggested Action to Fix
Cracks in Blade Bond is too hard for the material that is being cut. Use a blade with a softer bond.
Lost Segments Overheating can be caused by an inadequate supply of water or no water being supplied to a blade that requires it.

Of course there are many other problems that you could have with a blade that would be noticeable before the blade breaks, cracks, or loses segments. The key here is to keep your machine maintained and keep your blade fastened properly.

In this post, we have not covered every single cause of blade breakage. Rather we have taken a brief look at some of the basic causes. If you diligently keep coolant flowing all around your blade – whether your blade is liquid cooled or air cooled – and you keep your blade properly tightened and fastened to a well-maintained machine, you will get a full life from each blade you use properly.
