Abstract
A tool has at least one point, at least one working edge, at least one edge, which connects to the point and is located opposite of the working edge and which has at least one first edge region that is straight and forms an inclination angle between 0° and 2.5° with the working edge. The edge has a second edge region, which has a different inclination than the first edge region.
Claims18
A tool comprising:
- a tip,
- an end region defining a fastening element for fastening the tool to a tool holding unit, and
- a working portion defined between said tip and said end region and including a linear working edge and a second edge coextensive with the working edge and located directly opposite the working edge,
- said working edge defining saw teeth and being linear along an entire length of said working edge from said tip to said end region, said working edge defining a working stroke direction in which said tool is moved so that material is removed from a workpiece by said saw teeth, said working stroke direction extending from said tip to said fastening element, and
- said second edge adjoining the tip and including:
- a first edge region which is straight and includes a first angle of inclination away from said working edge of between 0° and 2.5° with the working edge;
- a second edge region between the first edge region and the tip which has a second angle of inclination different from said first angle of inclination relative to said working edge;
- and
- a third edge region arranged adjacent the first edge region at a distance from the second edge region and which has a third angle of inclination different from said first angle inclination relative to said working edge,
- wherein respective entire lengths of said first, second and third edge regions are all located directly opposite the working edge and all combine to form an entire length of said second edge, and
- wherein a distance between said working edge and said second edge increases in a direction opposite said working stroke direction from a minimum distance at said third region to a maximum distance at said second region and increases continuously along said first edge region from said third edge region to said second edge region.

A system comprising:
- a machine tool having a tool holding unit;
- and
- a tool including:
- a tip,
- an end region defining a fastening element for fastening the tool to the tool holding unit,
- a working portion defined between said tip and said end region and including a linear working edge and a second edge the working edge and located directly opposite the working edge,
- said working edge defining saw teeth and being linear along an entire length of said working edge from said tip to said end region, said working edge defining a working stroke direction in which said tool is moved so that material is removed from a workpiece by said saw teeth, said working stroke direction extending from said tip to said fastening element, and
- said second edge adjoining the tip and including:
- a first edge region which is straight and includes a first angle of inclination away from said working edge of between 0° and 2.5° with the working edge;
- a second edge region between the first edge region and the tip which has a second angle of inclination different from said first angle of inclination relative to said working edge;
- and
- a third edge region arranged adjacent the first edge region at a distance from the second edge region and which has a third angle of inclination different from said first angle inclination relative to said working edge,
- wherein respective entire lengths of said first, second and third edge regions are all located directly opposite the working edge and all combine to form an entire length of said second edge, and
- wherein a distance between said working edge and said second edge increases in a direction opposite said working stroke direction from a minimum distance at said third region to a maximum distance at said second region and increases continuously along said first edge region from said third edge region to said second edge region.

A tool comprising:
- a tip,
- an end region defining a fastening element for fastening the tool to a tool holding unit, and
- a working portion defined between said tip and said end region and including a linear working edge and a second edge the working edge and located directly opposite the working edge,
- said working edge defining saw teeth and being linear along an entire length of said working edge from said tip to said end region, said working edge defining a working stroke direction in which said tool is moved so that material is removed from a workpiece by said saw teeth, said working stroke direction extending from said tip to said fastening element, and
- said second edge adjoining the tip and including:
- a first edge region which is straight and includes a first angle of inclination away from said working edge of between 0° and 2.5° with the working edge;
- a second edge region between the first edge region and the tip which has a second angle of inclination different from said first angle of inclination relative to said working edge;
- and
- a third edge region arranged adjacent the first edge region at a distance from the second edge region and which has a third angle of inclination different from said first angle inclination relative to said working edge,
- wherein respective entire lengths of said first, second and third edge regions are all located directly opposite the working edge and all combine to form an entire length of said second edge,
- wherein the third edge region is parallel in relation to the working edge and directly adjoins the first edge region, and
- wherein a distance between said working edge and said second edge increases in a direction opposite said working stroke direction from a minimum distance at said third region to a maximum distance at said second region and increases continuously along said first edge region from said third edge region to said second edge region.
