Abstract
A reciprocating saw blade for a machine tool, in particular a jigsaw blade, includes a first row of saw teeth and a second row of saw teeth. The first and second rows of saw teeth are arranged at an angle to a longitudinal axis of the reciprocating saw blade. The angle of the first row of saw teeth opposes the angle of the second row of saw teeth. The reciprocating saw blade also includes a further row of saw teeth arranged between the first and second rows of saw teeth. The further row of saw teeth is set back, in particular suddenly set back, towards the longitudinal axis in relation to the first and second rows of saw teeth.
Claims19
A reciprocating saw blade for a power tool, comprising:
- a first row of saw teeth, the first row of saw teeth defining a first angle with respect to a longitudinal axis of the reciprocating saw blade;
- a second row of saw teeth, the second row of saw teeth defining a second angle with respect to the longitudinal axis, the first angle of the first row of saw teeth oriented oppositely to the second angle of the second row of saw teeth;
- and
- a further row of saw teeth arranged longitudinally between the first and second rows of saw teeth,
- wherein the further row of saw teeth is set back toward the longitudinal axis relative to the first and second rows of saw teeth such that a first tooth of the further row of saw teeth that is adjacent to the first row is set back toward the longitudinal axis from a longitudinal extension of a first profile of tooth tips of the first row of saw teeth, and a second tooth of the further row of saw teeth that is adjacent to the second row is set back toward the longitudinal axis from a longitudinal extension of a second profile of tooth tips of the second row of saw teeth, and
- wherein the set back of the first tooth and/or the set back of the second tooth is between 1% and 20% relative to a maximum width of the saw blade defined transversely to the longitudinal axis and parallel to a lateral face of the saw blade, wherein the further row of saw teeth is arranged on a straight line.
