Patent ID: 11376679

Abstract:
A bandsaw blade, including a main tooth group formed by nine sawteeth arranged in sequence, including three sub-tooth groups including a first sawtooth (1,4,7) of straight tooth, a second sawtooth (2,5,8) of left set tooth and a third sawtooth (3,6,9) of right set tooth. Each of sawteeth (1) and (4)-(6) has chamfers on two sides. Sawtooth (1) has a first height, sawtooth (4) has a second height and sawtooth (7) has a third height. Sawteeth (5) and (6) have the same fourth height. Sawteeth (2), (3), (8) and (9) have the same fifth height. The first through fifth heights are sequentially decreased. A top plane width of sawtooth (4) is larger than that of sawtooth (1). A top plane width of sawtooth (7) is larger than that of sawtooth (4). By using the bandsaw blade, more chips can be produced to reduce total cutting force and improve cutting efficiency.
