A method of using a reciprocating saw blade having an elongated body with a front body portion and a rear body portion, each having a front end, a rear end, an elongated cutting edge extending between the front and rear ends and a back edge opposite the cutting edge. A first tang that extends from the rear end of the rear body portion may be coupled to a reciprocating saw. The saw blade may be removed from reciprocating saw, and a second tang, which extends from the rear end of the front body portion, may be exposed by breaking off an entirety of the rear body portion in a single integral piece from the front body portion. The front body portion, without the rear body portion, may be coupled to the reciprocating saw by coupling the exposed second tang to the reciprocating saw.

Saw blade with multiple tangs and methods of use

A reciprocating saw blade for improving vibration and cordless runtime includes an elongated body having a front end portion and a rear end portion. An elongated cutting edge extends from the front end portion to the rear end portion and defines a longitudinal axis. An opposite non-cutting back edge extending from the front end portion to the rear end portion. The body has a thickness of approximately 0.89 mm to approximately 1.15 mm. A tang coupled to the rear end portion is configured to be coupled to a tool holder of a powered reciprocating saw. The cutting edge comprises a plurality of teeth and gullets. The teeth have a kerf width of approximately 1.29 mm to approximately 1.56 mm and are arranged in a pattern of alternating tooth pitch of a smaller first tooth pitch and a larger second tooth pitch.

Reciprocating saw blade

A saw blade includes an elongated body having a front end, a rear end, an elongated cutting edge extending between the front edge and the rear edge and defining a longitudinal axis, and a back edge opposite the cutting edge. A first tang is coupled to the rear end of the body and configured to couple the saw blade to a saw. The first tang faces a rearward direction away from the front end of the body. A second tang is defined in an intermediate portion of the body and configured to couple the saw blade to a saw. The second tang also faces the rearward direction. The second tang can be exposed by breaking off a portion of the body.

Saw blade with multiple tangs

A hole saw has a cup shaped body with a base, and a cylindrical wall with an extending cutting edge. An arbor extends from base. A plurality of teeth are formed on the cutting edge. The teeth having a repeating first and second tooth form. The first tooth form has a rake face and relief face defining the cutting edge. The rake face and relief face are at a desired angle. A first gullet is continuous with the first rake face so that it has a desired depth. The second tooth form has a second rake face and second relief face. The faces are on a desired angle. A second gullet is continuous with the second rake face providing a second tooth height. The second tooth height is greater than the first tooth height.

Hole saw blade

A reciprocating saw has a tooth form that decreases the cutting time of the saw blade and extends the life of the saw blade. The tooth height is longer than conventional metal cutting reciprocating saws. Also, the tooth form has a larger gullet. The tooth rake angle remains substantially constant during the life of the saw blade.
