Tool

A tool configured to be fastened to a hand-held power tool, the tool comprising:

• a saw blade composed of a bimetallic strip, the saw blade including:
• at least one main body;
• and
• at least one working part connected integrally to the at least one main body along a straight connecting edge, the at least one working part having at least one working edge having a set of saw teeth;
• and
• a fastening part to which the saw blade is connected in an overlapping manner,
• wherein the bimetallic strip comprises two different metal or metal alloy materials that are materially bonded together along the straight connecting edge,
• wherein the bimetallic strip comprises the at least one main body and the at least one working part,
• wherein the at least one working edge is shaped as a plurality of polygon segments including a first polygon segment, which is arranged substantially parallel to the straight connecting edge, and a second polygon segment and a third polygon segment, each of which is angled relative to the first polygon segment,
• wherein each of the first, second, and third polygon segments includes two end points,
• wherein each of the first, second, and third polygon segments includes at least three tooth tips,
• wherein the end points of the first, second, and third polygon segments are located on a circular path having a radius about an axis of rotation of the tool, and
• wherein the fastening part includes a form closure mechanism configured to transmit torque from the hand-held power tool and to define a rotary position of the saw blade relative to the hand-held power tool.
