Abstract

See full text

A saw blade includes a group A (group A1 [=straight tooth+the odd number of set teeth]+group A2 [=straight tooth+the even number of set teeth]) and a group B (group B1 [=straight tooth+the odd number of set teeth having opposite set-bending sides to those in the group A1]+group B2 [=straight tooth+the even number of set teeth having opposite set-bending sides to those in the group A2]). Wide and narrow set teeth are arranged so that a max/min ratio of the number of pitches between the narrow set teeth having identical set-bending side and set width is 1.8 or less, and a max/min ratio of the number of pitches between the wide set teeth having identical set-bending side set width is 2.7 or less.
