A circular saw blade includes a circular plate-like body having a first side face, an opposite second side face, a periphery, and a central opening defining a center point, and rotatable in a cutting direction. A plurality of circumferentially-spaced teeth are separated by a plurality of gullets. Each tooth has a rake face, a top face, a cutting edge at a junction between the rake face and the relief face, a first lateral face joined to the top face at a first top edge, and a second lateral face opposite the first lateral face and joined to the top face at a second top edge. The teeth include a plurality of first beveled teeth, each with its top face beveled radially inward from its first top edge to its second top edge, a plurality of second beveled teeth, each with its top face beveled radially inward from its second top edge to its first top edge, and a plurality of unbeveled teeth. The first beveled teeth, the second beveled teeth, and the unbeveled teeth are arranged in an alternating top bevel+raker pattern. The first top edge of the second beveled tooth is disposed radially inward toward the central opening from the first top edge of the first beveled tooth by a first drop distance.
