1. A saw blade, comprising:
- an unset tooth;
a left set tooth;
a right set tooth;
wherein the left set tooth and the right set tooth are set to a right-and-left direction;
wherein when a thickness of a body section of the saw blade is D, and a set width is T, and where α
is a setting coefficient, a relationship that T=D+2α
is established;
wherein a relationship between the thickness D of the body section and the coefficient α
is established in a manner such that when 0.85 mm≦

Abstract
A saw blade which has an unset tooth and left and right set teeth which are set to a right-and-left direction that, when a thickness of a body section of the saw blade is D and a set width is T, a relationship that T=D+2α; when the thickness D of the body section and the coefficient α establish a relationship that 0.85≦D≦0.95; 0.15≦α≦0.35. In addition, when 0.96<D≦1.2, 0.2≦α≦0.4 is established; when 1.2<D≦1.5. 0.25≦α≦0.43 is established; when 1.5<D≦1.7, 0.3≦α≦0.5 is established; and when 1.7<D, 0.35≦α≦0.6 is established.
