Abstract

A power tool system includes at least one power tool which has at least one workpiece support unit that is configured to support a workpiece during machining, and also includes at least one machining tool device which extends through a workpiece support surface of the workpiece support unit in at least one operating state. The machining tool device includes at least one cutting strand that is configured to be driven in circulation. A ratio of a maximum height of the workpiece support unit to a maximum cutting depth of the machining tool device is less than 4.1.

Claims (24)

1. A power tool system, comprising:

at least one power tool that includes at least one workpiece support unit that is configured to support a workpiece during machining; and

at least one machining tool device which extends through a workpiece support surface of the at least one workpiece support unit in at least one operating state, the at least one machining tool device including at least one cutting strand that is configured to be driven in circulation;

wherein a ratio between a maximum distance, extending in a direction extending at least substantially perpendicularly to the workpiece support surface, from the workpiece support surface to an underlying-surface contact surface of the power tool and a maximum cutting depth of the at least one cutting strand is less than 4.1:1 and more than 0.8:1, wherein the at least one machining tool device includes at least one guide unit which extends at least partially through the workpiece support surface in the at least one operating state and is configured to guide the at least one cutting strand, wherein the at least one power tool includes at least one tool receptacle that, for machining a workpiece, is configured to fix the at least one machining tool device to the at least one power tool via at least one of a form-fitting connection and a force-fitting connection.

2. A power tool system, comprising:

at least one power tool that includes at least one workpiece support unit that is configured to support a workpiece during machining; and

at least one machining tool device which extends through a workpiece support surface of the at least one workpiece support unit in at least one operating state, the at least one machining tool device including at least one cutting strand that is configured to be driven in circulation;

wherein a ratio between a maximum distance, extending in a direction extending at least substantially perpendicularly to the workpiece support surface, from the workpiece support surface to an underlying-surface contact surface of the power tool and a maximum cutting depth of the at least one cutting strand is less than 4.1:1 and more than 0.8:1, wherein the at least one machining tool device includes at least one guide unit which extends at least partially through the workpiece support surface in the at least one operating state and is configured to guide the at least one cutting strand, wherein the at least one cutting strand and the at least one guide unit are configured as a closed system.

3. The power tool system according to claim 2 , wherein the ratio is less than 3.5:1.

4. The power tool system according to claim 2 , wherein the maximum distance is less than 235 mm.

5. The power tool system according to claim 2 , wherein:

the at least one power tool has at least one tool drive shaft;

the at least one tool drive shaft is spaced apart from the at least one cutting strand by a minimum distance along a longitudinal axis of the at least one machining tool device; and

the minimum distance is less than the maximum cutting depth of the at least one cutting strand.

6. The power tool system according to claim 2 , wherein:

the at least one cutting strand comprises a plurality of cutting strands;

each of the plurality of cutting strands defines a respective maximum cutting depth;

each of the respective maximum cutting depths is a depth different from the other of the respective maximum cutting depths;

the at least one power tool includes at least one tool drive shaft;

the at least one tool drive shaft is spaced apart from each of the plurality of cutting strands by a respective minimum distance along a longitudinal axis of the at least one machining tool device when each of the plurality of cutting strands is mounted on the at least one tool drive shaft; and

each of the respective minimum distances is the same as the other of the respective minimum distances.

7. The power tool system according to claim 2 , wherein the at least one power tool includes at least one tool receptacle that, for machining a workpiece, is configured to fix the at least one machining tool device to the at least one power tool via at least one of a form-fitting connection and a force-fitting connection.

8. The power tool system according to claim 2 , wherein the at least one machining tool device, when positioned on the at least one power tool, is mounted so as to be movable in translation in a direction extending at least substantially parallel to the workpiece support surface.

9. The power tool system according to claim 2 , wherein the at least one machining tool device, when positioned on the at least one power tool, is mounted so as to be pivotable with respect to the at least one power tool about a pivot axis extending at least substantially parallel to the workpiece support surface.
