Abstract
The present invention provides a band saw blade which has less difference in cut areas of workpieces with small diameters and cut areas of workpieces with large diameters, and is capable of weakening the cutting resistance and preventing unintentional bending of a cutting line and noise generation when a workpiece, which cannot easily be cut, is cut. The band saw blade has, on the back surface of a body thereof, a wavy back surface which is changed periodically or irregularly. A plurality of imaginary curves L ,L running parallel to the wavy undulation provided for the back surface are formed opposite to the back surface. Moreover, a plurality of saw teeth having tooth tips which substantially describe the imaginary curves L ,L are formed. Thus, constant areas can be cut by the band saw blade regardless of the diameter of the workpieces required to be cut. Moreover, the cutting resistance can be weakened, and unintentional bending and noise can be prevented.
