Tremain explains, "You would not want to use a blade designed to be used on a high-horsepower [flat] saw on a low-horsepower saw. If this happens, the blade could close up and stop cutting. On the other hand, you would not want to use a blade designed to be used on a low-horsepower saw on a high-horsepower saw. This could result in the blade wearing out very quickly - potentially even before the job is finished."
Your blade supplier can help ensure you properly match saw and blade speed. "Call the manufacturer and advise them how much and how deep you have to cut and what the horsepower of the saw is," says Delahaut, "and they will be happy to provide you with the right blade that will give you the best performance."
