A plurality of cutting bodies each having a cutting edge are arranged on the main body of a machining tool. During operation, the plurality of cutting bodies rotate in a direction of rotation which runs around an axis of rotation. Each cutting edge has exactly one reference point. The reference points are mutually spaced in the direction perpendicular to the direction of rotation. Reference points of cutting bodies that are directly adjacent in the direction perpendicular to the direction of rotation are arranged with mutual angular spacings with respect to the axis of rotation. The spacings are integer multiples of angle values which lie in an angle range of +/−5° with respect to the golden angle. The sum of the golden angle and an opposite angle produces the round angle. The ratio of golden angle to opposite angle is equal to the ratio of opposite angle to round angle.
A machining tool has a main body with a carrier surface. Cutting bodies each having a cutting edge are arranged on the carrier surface, the edges rotating in a direction of rotation which runs around an axis of rotation during the machining. The edges of a group including a plurality of cutting bodies overlap in a gapless manner with respect to the direction perpendicular to the direction of rotation and form an overall edge. All of the edges are arranged between end points of the overall edge. The group has a minimum number of teeth defined by the number of edges at least situated one behind the other in the direction of rotation in an intermediate region of the overall edge. The edges of the group overlap with respect to the direction perpendicular to the direction of rotation such that the minimum number of teeth is at least two.

Tool unit and switchable tool system for a tool unit
A tool unit includes a tool head, a motor and a switching drive for the head. The head has a first section with first blades and a second section with second blades. The second section is movable to and fro between a passive and an active position relative to the first section, the second blades being retracted in the passive position, and the second blades projecting axially beyond the first blades in the active position. The drive includes an electromagnet and an actuating armature made from magnetically attractable material and is arranged in the region of action of the electromagnet. The electromagnet is positioned between the head and the motor and is fastened to a housing part of the motor such that it cannot be rotated. The armature is connected fixedly to the second section. A gap remains between the electromagnet and the armature in the passive and active position.
A tool head is for machining edges of a workpiece and includes a first tool section with first blades and a second tool section with second blades. The second blades are positioned between the first blades when seen in the circumferential direction.
