Tooth form design for reciprocating saw blade

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 distance from said tip to the intersection of said rake face and said first 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;
• and
• 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.

A reciprocating saw blade having a plurality of teeth, comprising:

• said teeth each having a tooth form including:
• 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 distance from said tip to the intersection of said rake face and said first 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;
• and
• 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.
