Abstract:
In a power tool with two cutting wheels ( 11, 12 ), which rotate past each other in opposite directions, rest directly against each other, and can be driven by two drive spindles ( 14, 15 ) disposed concentrically to each other, and with a tool fitting ( 13 ) for the cutting wheels ( 11, 12 ) that has a support flange ( 18, 24 ), which is non-rotatably connected to the respective inner or outer drive spindle and provides a centered support and form-fitting rotary slaving for the cutting wheels ( 11, 12 ), and has clamping means for securing the form-fitting engagement between the cutting wheels ( 11, 12 ) and the support flanges ( 18, 24 ), in order to produce a simple design of the tool fitting ( 13 ), with a high operational reliability and a low space requirement, as well as tool-free changing of the cutting wheels, the clamping means have a screw part ( 27 ), which supports the second support flange ( 24 ) and whose end can be screwed without tools into the inner drive spindle ( 15 ), and have a clamping part, which can be actuated without tools, presses the second support flange ( 24 ) axially against the inner drive spindle ( 15 ), and clamps the second support flange ( 24 ) in relation to the screw part ( 27 ) (FIG. 1 ).
