<p>A bandsaw blade comprises a plurality of cutting teeth spaced longitudinally apart by gullets (11). Each tooth includes a steel portion (12) and a carbide tip (13) brazed to front face of the steel portion. The deepest point (22) of the gullet lies on a curved section having a relatively large radius of curvature (21), and is spaced longitudinally forwardly of the trailing carbide tip by a relatively large distance (40). Transversely spaced corners (32, 33) of the gullet bottom are made smoothly rounded by a shot-peening operation.</p> |
