Saw blade
First Claim
1. A saw blade provided with numerous cutting teeth for cutting a workpiece at appropriate pitches, the saw blade comprising:
- left and right set teeth, which are set in a lateral direction, as viewed in a cutting direction of the cutting teeth;
wherein each of the left and right set teeth is a dovetail shaped set tooth having a tooth tip which is gradually enlarged in the lateral direction in addition to being set, each of the left teeth having a left side surface at the dovetail shaped portion and each of the right teeth having a right side surface at the dovetail shaped portion, so that each inclination angle of the left side surface and the right side surface is increased as a result of both the dovetail shape and set of the tooth tip; and
a straight tooth, which is not set in the lateral direction, as viewed in the cutting direction of the cutting teeth,wherein the straight tooth including a dovetail shaped straight tooth having a tooth tip which is gradually enlarged in the lateral direction, andwherein an upper surface of each tooth, including the tooth tip, defines a planar inclined surface.

Abstract
A saw blade includes left and right set teeth which are set in a lateral direction, as viewed in a cuffing direction of cutting teeth. The left and right set teeth include dovetail shaped set teeth, each having a tooth tip formed into a dovetail shape gradually enlarged in the lateral direction, respectively; and a straight tooth, which is not set. The straight tooth includes a dovetail shaped straight tooth having a tooth tip formed into a dovetail shape gradually enlarged in the lateral direction. In the straight tooth, inclinations are formed on both of left and right ends at the tooth tip, which is formed into the dovetail shape gradually enlarged in the lateral direction.
