TOOL DEVICE

Japanese Patent JP2022033969

A

To provide a tool device suitable for use in a manual machine processing tool.SOLUTION: A tool device comprises an attachment device for receiving driving force from a driving device. The attachment device comprises at least two driving areas spatially separated from a tool rotary shaft. The driving device has a surface in a shape fitting to the driving areas, which engages with the attachment device and transmits driving force from the driving device to the attachment device. Each of the driving areas has a plurality of surface points, where tangent planes on the surface points incline with respect to axial planes and the tangent planes incline with respect to radial planes extending perpendicularly with respect to the tool rotary shaft. The tool device comprises, in a region of the attachment device, a first upper boundary plane and a second lower boundary plane. The boundary planes are perpendicularly arranged with respect to the tool rotary shaft and both boundary planes are spatially separated from each other. The driving areas are arranged between both boundary planes.SELECTED DRAWING: Figure 18
