The Craftsman Scroller Saw has a wide selection of blades for cutting different types of materials. Blades meant to cut wood typically have less teeth per inch than compared to metal cutting blades. For cutting tree branches and logs, use the 6 inch blade with 7 teeth per inch on medium speed. Metals such as copper, aluminum and brass are meant to be cut using the 3 inch blade that has 24 teeth per inch on high speed. Consult the manufacturer's manual to see the complete list of recommended blades and speeds.
