Rake angle - determines the cutting characteristics of a saw blade. It is a measurement of the angle of the tooth face in relation to an imaginary radial line drawn from the exact center of the saw blade through the very tip of the saw tooth. Positive rake teeth have a forward tilt while negative rake teeth have a backward tilt. Blades with a high positive rake are aggressive and fast-cutting. Blades with a lesser rake take smaller bites and are easier to control for fine finishes and precise cuts.
