摘要： A hard tip band-saw blade includes alternating sawtooth groups. Each of the sawtooth groups includes two sawtooth subgroups. The first sawtooth subgroup includes, as a plurality of sawteeth, a first leading tooth and a first following tooth and the second sawtooth subgroup includes, as a plurality of sawteeth, a second leading tooth, a second following tooth, and a third following tooth. Each tooth top corner part of a hard tip of the first following tooth, a tooth top corner part on a left side of a hard tip of the second following tooth, and a tooth top corner part on a right side of a hard tip of the third following tooth most outwardly protrude in a left-right direction.
