A saw blade comprising a substantially circular integral main body with a plurality of circumferentially spaced cutter tips secured thereto and projecting radially outwardly therefrom, the outer end of a tip being positioned to describe an arc during rotation of the blade which is at a first radius, a tip having a front surface in the direction of rotation of said blade during operation, said main body having a peripheral edge defining a circular arc at a second radius throughout a major portion of its circumference, a depth gauge portion on said main body associated with and leading a tip and having a radially outwardly facing guide surface which describes an arc at a third radius during rotation which is intermediate said first and second radii, said guide surface of the depth gauge portion being connected with the peripheral edge of said main body through a transition section which curves from concave to convex on progressing from said peripheral edge to said guide surface, and a chip clearance channel intermediate said front face of a cutter tip and its associated depth gauge, said channel extending generally radially inwardly from said guide surface to a region spaced radially inwardly from said second radius and having a width measured circumferentially of said blade in a range of 0.030 to 0.100 inch.
