Bi-metal blades are highly flexible and tough because of a combination of HSS and HCS. Suitable for the most demanding applications when there is a risk of shank breakage or when an extremely versatile blade is required. Bosch bi-metal jig saw blades last twice as long as HSS blades and 10 times longer than HCS blades. Used for wood, metal, non-ferrous metals and aluminum.
