The Diamond Blades can seemingly be frustrating when they don't perform to your expectations! The root cause is not understanding the why's and wherefores of different applications that they are manufactured for. Common problems are rapid blade wear, stops cutting properly, having to push to finish the cut, cuts too slow, segment loss, under cutting and so on. This is especially frustrating when common sense dictates that you buy the best blades to save time and effort. Wrong Wrong!!!! The best and most expensive blades will wear out in a matter of hours, when used in the WRONG application. NO BALDE CAN BE USED IN ALL APPLICATIONS! Remember this when you purchase your next blade. We have the right blade to for ALL of your jobs.
