Patent ID: 7225714

Claim:
A reciprocating saw blade tooth form comprising: a rake face and a relief face, said rake face intersecting said relief face at a tip of said tooth form; said rake face extending from said tip to a first gullet, said rake face being continuous with said gullet; said relief face extending from said tip to a second gullet, said relief face continuous with said second gullet, said relief face being on an angle with respect to a horizontal plane at the intersection of said relief face and said rake face, said angle defining a relief angle; said rake face being on an angle with respect to a vertical plane at the intersection of said relief face and said rake face, said angle defining a rake angle; an included angle is defined as the angle between the relief face and the rake face; a tooth depth is a length from said tip of the tooth to a curved portion of the gullet; a maximum gullet depth is a distance from said tip to the bottom of the first gullet; a pitch length is a distance between adjacent tips; said relief angle being between about 38° to about 42°, said included angle being from about 45° to about 50° and said tooth depth being about 30% to about 47% of the maximum gullet depth and about 18% to about 26% of the pitch length wherein said tooth form enables better chip ejection which enables faster cutting of the blade; and said first and second gullets are defined by a radius, the radius has a length having a radius of about 52% to about 55% of the maximum gullet depth.
