What Makes A Good Diamond Blade? Easy, Diamond Content 💎♕


I get asked what makes a good diamond blade almost daily. Trust me, there isn’t one simple answer to this question. When those telemarketers call you, pushing you to buy their indestructible diamond blade, just ask them, what is the diamond content of that blade. I will guarantee you, they won’t have the answer! That is unless, they read this article or just blurt out a nice guess …98%???? 

There is actually only 3 answers to the diamond content question. In regards to regular general purpose diamond blades that go on a cut off saw, the diamond content is not as much of a factor as it is for professional diamond blades built for high speeds.

First is the lower end of diamond content in blades. This metric is 35% diamond content. This is the lower end and will limit how much life and cutting action the diamond blade will actually provide. The middle diamond content is 40%. This is most diamond blades on the market. These will be moderately priced and offer good solid life. Any contractor that is cutting concrete and asphalt on a regular basis. Any concrete PRO or road cutting pro should be investing their money is diamond blades with diamond content of 45%. This will be the best bang for your buck and offer the greatest linear footage and cutting action.

In closing, 40% diamond content in blades is more than satisfactory. If you watch the video, you can hear us explain that this is mostly in regards to pro blades, typical 14″ diamond blades for asphalt and concrete will almost always have 35-40% diamond content.
