  • Publication number: 20220331889
    Abstract: The disclosure relates to a saw tool for use with a multifunctional machine tool which can be driven in oscillation. The saw tool has at least one main axis, at least one main body, and at least one cutting arm arranged on the main body transversely to the main axis, the cutting arm having a first cutting region and a second cutting region starting from the main axis in a direction pointing away from the main body and running at least substantially perpendicular to the main axis, said cutting regions arranged one behind the other, and directly adjacent to each other. The second cutting region is arranged on the first cutting region, on a side of the first cutting region furthest from the main body, and has a greater mass than the first cutting region.

  • Publication number: 20220072639
    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.
