Diamond blades are a very useful power tool accessory for various DIY & construction jobs, and they are definitely worth investing in for your project. However, many users will wear out diamond blades quicker than expected, or the material won’t cut, and this is due to the many myths and misconceptions about diamond blades that mislead customers into purchasing the wrong blade. The purpose of this blog is to go through a list of common myths, so you know what to look out for when purchasing your next diamond blade.


The bigger the segment, the more efficient the blade:

False. A common misconception is that the bigger the segment of a diamond blade, then the longer the blade will last. This statement is actually false. The life of a diamond blade is dependent on the concentration of diamond, coolant, operation speed, material, depth of the cut; there are so many variables that can affect the lifespan of a blade, and the segment size is not one of them.


Blades designed to “cut all” materials are the best blade:

False. You will notice that some blades are advertised to “cut all” materials, which is in fact true. However, this doesn’t mean they are the best blade for the job, making this statement false. To obtain the feature of cutting all blades, it means the blade doesn’t specialise on one specific material. For example, a blade designed for cutting class A engineering brick will most likely be more efficient at cutting class A engineering brick that a “cut all” blade. The difference is that class A engineering brick will be all that blade can cut efficiently. The “cut all” blade will be able to cut other materials as well, just less efficiently.


Cheap blades will be as good as expensive ones:

False. You get what you pay for when it comes to diamond blades. The difference is usually to do with the concentration of synthetic diamonds within the blade, as well as the quality of the diamonds. Laser welded blades will also typically cost more, as they are more efficient.
