Abstract
A band saw blade includes: a body portion having a band-like and an endless shape; a tooth portion in which a tooth group, which is a set of a predetermined number of teeth including a set tooth, is repeatedly formed on one edge side of the body portion; and a coat layer which is formed on a surface of the teeth of the tooth portion. The set tooth has a first indentation portion as a recessed portion in the coat layer on an outer surface in a set direction, and thickness of the coat layer in the recessed portion of the first indentation portion is thinner than that of the coat layer in portions other than the recessed portion.
Claims4
A band saw blade comprising:
- a body portion having a band-like and an endless shape;
- a tooth portion in which a tooth group, which is a set of a predetermined number of teeth including a set tooth, is repeatedly formed on one edge side of the body portion;
- and
- a coat layer which is formed on a surface of the teeth of the tooth portion, wherein
- the set tooth has a first indentation portion as a recessed portion in the coat layer on an outer surface in a set direction, and
- thickness of the coat layer in the recessed portion of the first indentation portion is thinner than that of the coat layer in portions other than the recessed portion.
A method for manufacturing a band saw blade which is provided with a body portion having a band-like and an endless shape;
- a tooth portion in which a tooth group, which is a set of a predetermined number of teeth including a set tooth, is repeatedly formed on one edge side of the body portion;
- and a coat layer which is formed on a surface of the teeth of the tooth portion, the method comprising:
- performing a coat layer formation step of forming the coat layer on the teeth of an intermediate blade in which the teeth are all straight teeth, and then performing set processing of setting and forming a predetermined tooth into the set tooth.
