metal cutting wheels is very quickly

You should check what diameters of metal cutting wheels your concrete saw can accommodate, and the saw’s arbor size which the arbor hole on the diamond blade should match. Also, you should examine the horsepower of the concrete saw. The saw’s horsepower affects the diamond blade selecting. The diamond segment of the metal grinding disc used on big horsepower saws should have harder bond or higher diamond concentration, otherwise the diamond segments (the teeth) of the blade may be consumed very quickly.
