Abstract
A saw blade comprising a series of teeth at a longitudinal edge thereof, arranged in alternate directions and formed in a tooth shape as defined by a first flank angle, a second flank angle, and a rake angle, is characterized in that the first flank angle lies between approximately 50.0° to 54.0°, the second flank angle lies between approximately 14.0° to 16.0°, and the rake angle lies between approximately 11.0° to 14.0°.
Claims18
A saw blade comprising a series of teeth at a longitudinal edge thereof, said teeth arranged in alternate directions and each tooth comprising a rake edge, a first flank and a second flank formed in a shape which is defined by said rake edge defining the front of the tooth, said second flank extending from the base of the tooth and said first flank extending from the second flank to said rake edge, a first flank angle α, between a first flank of the tooth and a line perpendicular to the saw blade, in a plane parallel to the longitudinal edge, a second flank angle β, between a second flank of the tooth and a line perpendicular to the saw blade, in said plane, and a rake angle γ, between a rake edge of the tooth and a line perpendicular to the saw blade, in said plane, wherein the first flank angle α lies between about 50.0° to 54.0°, the second flank angle β lies between about 14.0° to 16.0°, and the rake angle γ, lies between about 11.2° to 14.0°.
A saw blade comprising a series of teeth at a longitudinal edge thereof, said teeth arranged in alternate directions and extending along said longitudinal edge to create a cutting plane and each tooth comprising a rake edge, a first flank and a second flank formed in a shape which is defined by said rake edge defining the front of the tooth, said second flank extending from the base of the tooth and said first flank extending from the second flank to said rake edge, a first flank angle α, between a first flank of the tooth and a line perpendicular to the saw blade, in a plane parallel to the longitudinal edge, a second flank angle β, between a second flank of the tooth and a line perpendicular to the saw blade, in said plane, and a rake angle γ, between a rake edge of the tooth and a line perpendicular to the saw blade, in said plane, wherein the first flank angle a lies between about 50.0° to 54.0°, the second flank angle β lies between about 14.0° to 16.0°, and the rake angle γ, lies between about 11.2° to 14.0°.
