Flexback band saw blades are made from carbon steel and feature a hardened tooth edge and flexible backing. They are very versatile and affordable. Flexback saw blades are a great choice for cutting wood, plastics and aluminum. They can also be used to occasionally cut steel, but they will not last nearly as long in steel as a bi-metal saw blade. Remember you can contact us for any custom size of band saw blade and we ship within 1 business day.
