SAW BLADE
摘要:
A reciprocating saw blade includes a body defining a longitudinal axis, an attachment configured to couple to a reciprocating saw, and a cutting portion. The cutting portion includes a plurality of cutting teeth, each having a tip and a rake face. The saw blade also includes a plunge point for initiating a plunge cut. The plunge point includes a leading tooth having a tip and a rake face extending from the tip. The tips of the plurality of cutting teeth and the tip of the leading tooth define a plane that is generally parallel to the longitudinal axis. A first angle between the plane and the rake face of the leading tooth, measured through the leading tooth, is greater than 90 degrees. A second angle between the plane and the rake face of each cutting tooth, measured through the corresponding cutting tooth, is less than 90 degrees.
