Abstract

The disclosure relates to a system having at least one first oscillation insert tool that is configured to be effectively coupled to an oscillation hand power tool, and at least one second oscillation insert tool that differs from the first oscillation insert tool and is configured to be effectively coupled to the oscillation hand power tool as an alternative to the first oscillation insert tool. At least one of the at least two oscillation insert tools comprises at least one compensating unit for at least substantially adapting a mass moment of inertia of the at least one oscillation insert tool to a mass moment of inertia of the at least one second oscillation tool.

First claim

The invention claimed is:

1. A system comprising:
a first oscillating insert tool that is configured to be operatively coupled to an oscillating hand power tool; and
a second oscillating insert tool that differs from the first oscillating insert tool and that, as an alternative to the first oscillating insert tool, is configured to be operatively coupled to the oscillating hand power tool,
wherein at least one of the first and second oscillating insert tools includes at least one compensating unit configured to adapt a first mass moment of inertia of the first oscillating insert tool about an oscillation axis in an operating state of the oscillating hand power tool and a second mass moment of inertia of the second oscillating insert tool about the oscillation axis in the operating state to one another in such a way that a difference between the first mass moment of inertia and the second mass moment of inertia is less than 20% of a greater of the first mass moment of inertia and the second mass moment of inertia.

2. The system as claimed in claim 1 , further comprising:
a third oscillating insert tool, which, as an alternative to the first oscillating insert tool and the second oscillating insert tool, is configured to be operatively coupled to the oscillating hand power tool,
wherein the at least one compensating unit is further associated with the third oscillating insert tool so as to adapt a third mass moment of inertia of the third oscillating insert tool.

3. The system as claimed in claim 1 , wherein the at least one compensating unit is disposed, at least partially, radially outside of a receiving region of a basic body of the at least one of the first and second oscillating insert tools.

4. The system as claimed in claim 1 , wherein the at least one compensating unit is constituted, at least partially, by at least one mass reduction disposed, at least partially, between a working region and a receiving region of a basic body of the at least one of the first and second oscillating insert tools.

5. The system as claimed in claim 1 , wherein the at least one compensating unit is constituted, at least partially, by at least one additional mass.

6. The system as claimed in claim 5 , wherein a receiving region is disposed, at least partially, between a working region of the at least one of the first and second oscillating insert tools and the at least one additional mass.

7. A working unit comprising:
an oscillating hand power tool including a tool receiver, a vibration compensating unit, and having an oscillation axis in an operating state of the oscillating hand power tool; and
a system including (i) a first oscillating insert tool that is configured to be operatively coupled to the tool receiver, and (ii) a second oscillating insert tool that differs from the first oscillating insert tool and that, as an alternative to the first oscillating insert tool, is configured to be operatively coupled to the tool receiver,
wherein at least one of the first and second oscillating insert tools includes at least one compensating unit configured to adapt a first mass moment of inertia of the first oscillating insert tool about the oscillation axis and a second mass moment of inertia of the second oscillating insert tool about the oscillation axis to one another in such a way that a difference between the first mass moment of inertia and the second mass moment of inertia is less than 20% of a greater of the first mass moment of inertia and the second mass moment of inertia, and
wherein the vibration compensating unit is configured to compensate, at least partially, the first mass moment of inertia when the first oscillating insert tool to a is operatively coupled to the tool receiver and the second mass moment of inertia when the second oscillating insert tool is operatively coupled to the tool receiver.
