Abstract
A band saw blade may include a cutting edge defined by a number of teeth. Each tooth may include a tip, a rake face, a primary clearance surface defining a primary relief angle, a secondary clearance surface defining a secondary relief angle greater than the primary relief angle, a tertiary clearance surface defining a tertiary relief angle greater than the secondary relief angle, a first curvilinear protrusion formed between the secondary clearance surface and the tertiary clearance surface, a gullet surface, and a second curvilinear protrusion formed between the rake face and the gullet surface. The teeth may be spaced at varying pitch distances such that a difference between a minimum teeth per inch (TPI) based on a maximum pitch distance and a maximum TPI based on a minimum pitch distance is equal to or greater than 1, and may define a kerf width between 0.115 inches to 0.140 inches.
