Abstract
A tool, in particular a plunge-cut saw blade, includes a saw blade that has at least one main body and at least one working part. The working part has at least one working edge with saw teeth and is connected integrally to the main body along a straight connecting edge. The working edge includes a curved and/or polygon-like formation thereon.
Claims20
A 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 main body along a straight connecting edge, the working part having at least one working edge having a set of saw teeth;
- and
- a fastening part configured to center the tool for oscillation about a rotation axis, the main body fastened to the fastening part in an overlapping manner,
- wherein the working edge is defined by a shortest, continuously-curved connecting line touching each tooth tip of the set of saw teeth, the connecting line having a curvature that differs in degree along a length of the working edge, and
- wherein the bimetallic strip defines a first straight edge of the main body, the first straight edge oriented at least substantially parallel to the straight connecting edge and facing toward the rotation axis.
4 more elements
A method for producing a tool, comprising:
- parting off a bimetallic strip from a bimetallic band to form a saw blade of the tool, the bimetallic band having a first portion and a second portion connected integrally to the first portion along a straight connecting edge such that, when the bimetallic strip is parted off, the first portion defines at least one main body of the saw blade and the second portion defines at least one working part of the saw blade;
- and
- forming a set of saw teeth in at least one working edge of the working part, the working edge defined by a shortest, continuously-curved connecting line touching each tooth tip of the set of saw teeth, the connecting line having a curvature that differs in degree along a length of the working edge.
