Abstract
A circular saw blade having a plurality of circumferentially-spaced cutter teeth projecting radially outwardly therefrom. A portion of the periphery of the blade rises gradually as it progresses toward the front face of a tooth to provide a depth gauge to control depth of cut. A chip clearing channel extends radially inwardly along the body of the blade adjacent the front face of the tooth. A pocket formed in the body has edge margins which receive and support front and rear surfaces of a cutter tip.
Claims14
A saw blade comprising a generally circular main body having a plurality of circumferentially-spaced cutter teeth arrayed about the periphery thereof, the outer ends of said teeth being positioned to describe an arc at a preselected first radius during operation of said blade, a tooth having a front surface facing in the direction of rotation of said blade during operation and a rear surface facing in the opposite direction, a peripheral portion of said body intermediate adjacent cutter teeth having a first region adjacent the rear surface of one tooth which is spaced radially outwardly from the center of rotation of the blade a second distance which is less than said first radius, with said peripheral edge extending from said first region toward the forward surface of the following tooth in a substantially continuous curve to terminate adjacent the forward surface of the following tooth at a second region which is spaced radially outwardly from said center of rotation a third distance which is intermediate said first radius and said second distance.
A saw blade comprising a generally circular main body having a plurality of circumferentially-spaced cutter teeth arrayed about the periphery thereof, the outer ends of said teeth being positioned to describe an arc at a preselected first radius from the center of rotation of the blade during operation of the blade, a tooth having a front surface facing in the direction of rotation of said blade during operation and a rear surface facing the opposite direction, a peripheral edge portion of said body intermediate adjacent cutter teeth defining a section of a circle having as its center a point which is offset radially of said blade from the center of rotation of the blade whereby said peripheral edge portion of said body forms a ramp surface which increases in distance from the center of rotation of the blade on progressing from a region adjacent the rear surface of one tooth toward the front surface of the following tooth, terminating at a maximum distance from said center of rotation which is less than said first radius to provide depth of cut control for said following cutter tooth.
