A bimetal blade is a type of band saw blade that consists of two distinct metals joined together. The cutting edge is made from high-speed steel (HSS) for increased hardness and wear resistance, while the backer is made from a flexible, fatigue-resistant alloy for durability and reduced blade breakage. Bimetal blades are suitable for cutting various materials, including metals, plastics, and composites, and offer longer service life compared to carbon steel blades.
