BAND SAW BLADE FOR CUTTING STRUCTURAL WORKPIECES

A band saw blade (100， 200) may include a cutting edge (102，202) defined by a number of teeth (110，210). Each tooth (110A，110B，110C，110D，110E，110，1，210A，210B，210C 210D，210E，210) may include a tip (112，212)， a rake face (114，214)， a primary clearance surface (116，216) defining a primary relief angle， a secondary clearance surface (118，218) defining a secondary relief angle (A2) greater than the primary relief angle， a tertiary clearance surface (120，220) defining a tertiary relief angle greater than the secondary relief angle (A2)， a first curvilinear protrusion (122，132，222，232) formed between the secondary clearance surface (118，218) and the tertiary clearance surface (120，220)， a gullet surface (130)， and a second curvilinear protrusion (122，132，222，232) formed between the rake face (114，214) and the gullet surface (130). The teeth (110，210) may be spaced at varying pitch distances such that a difference between a minimum teeth (110，210) per cm (TPcm) based on a maximum pitch distance (P2，P4，P5) and a maximum TPcm based on a minimum pitch distance (P2，P4，P5) is equal to or greater than 1， and may define a kerf width (K) between 0，29 cm (0，115 inches) to 0.36 cm (0，140 inches).
