Subject: Re: Best Way to Cut PCB

No, not really. The problem with that Ryobi is that it is designed for cutting wood, which means that the blade speed will be relatively high. This will tend to kill the blade very quickly, as it heats up due to friction, then loses its temper, then loses its teeth. This is the sort of saw that gives bandsaws a bad name for eating up blades when cutting PCB.

Much better are the saws designed for cutting metal, which move the blade about 1/10 the speed of a wood cutting saw. Along with a fine-tooth metal-cutting blade, you can cut PCB all day long without eating up the blade. Here's what you really need:
