Unfortunately, not all Diamond Blades last forever. If you know when your Diamond Blade is starting to wear down, it will slowly start to lose its effectiveness. The results of using a worn diamond blade are hard to see, but if you compare a brand new blade to a week-old blade that has been used, you will definitely notice the difference. If you learn to notice when it wears out, then you will save time, and your work will become more efficient. 

 

Nevertheless, a diamond blade is not blunt or have dull edges like a Jigsaw Blade or Sabre saw blade. This means you can’t just replace it when you notice it’s dull. You have to pay attention to the type of blade cut and if it is different from the first time you use it. Your diamond blade will likely need to be replaced even if it still cuts. A fast, clean cut is always better than a slow, dull one.
