<p>A bandsaw blade comprises a plurality of cutting teeth spaced longitudinally apart by gullets. Each tooth includes a steel portion and a carbide tip brazed to a front face of the steel portion. The deepest point of the gullet lies on a curved section having a relatively large radius of curvature, and is spaced longitudinally forwardly of the trailing carbide tip by a relatively large distance. Transversely spaced corners of the gullet bottom are made smoothly rounded by a shot-peening operation.</p> |
