Tooth Rake Angle

The tooth rake angle, also known as the tooth cutting angle or attack angle, is the angle between the tooth face of a band saw blade or other cutting tool and an imaginary line perpendicular to the blade’s body. The tooth rake angle affects the blade’s cutting performance, chip removal efficiency, and cutting forces. Different rake angles are suitable for different materials and cutting applications: a positive rake angle for softer materials and a negative rake angle for harder materials, for example.
