Generally speaking, though, professionals tend to avoid this method. That's because it is overall rather slow, even when it comes to slicing thick metal stock. This method also burns through blades quickly due to the thin nature of a band saw blade. In turn, this method can get expensive fast if it is used with any regularity. Summary
