Diamond blades need to be replaced. The frequency of switching out blades depends on a bunch of factors. It depends on the diamond blade itself, the material being cut, the saw, the operator, and if you are cutting wet or dry etc. With these things being considered, I’m going to let you in on a little secret to extend your diamond blades life. Dress the diamond blade! I don’t mean put pants and a t shirt on it, I mean resharpen it… sort of. So, what is dressing a diamond blade? And more importantly, how do I dress a diamond blade?
Dressing a diamond blade is in a sense, resharpening it. In reality, you can’t sharpen a diamond blade at all but, you are wearing away a layer of flat diamonds that have glazed over. Diamond segments can sometimes glaze over or melt when the diamond blade heats up too much during cutting. This makes the diamond blade appear to be junk, however, underneath the melted segments are a fresh new layer of diamond ready to cut your concrete or asphalt.
Dressing the diamond blade is a simple process. You have to have some material on hand that will wear away the layer of glazed diamonds onto the next.
