A milling tool for working non-metal materials, in particular wood, engineered wood, and plastic, includes a carrier body, a plurality of cutting elements, which can be inserted into said body on the periphery in a corresponding number of openings extending in the radial direction and can be screwed to the carrier body by way of a bore and which have a plate-shaped and in the cross-section a substantially triangular-shaped design and on a side edge are provided with a blade. The cutting element includes: the region located opposite of the blade is rounded, a groove extending substantially at a right angle to the blade is provided in the bottom, the bore divides the groove preferably into two regions. The opening includes: a web, which extends radially upward from the bottom of the opening serving as a support surface for the cutting element and which corresponds with the groove, a radial threaded bore, which preferably divides the web into two regions, and the cutting element has contact with the opening only with the bottom thereof, a side wall of the groove and part of the region located opposite of the blade.

A cutter assembly is configured to interchange a cutter bit and has a plurality of retaining features to secure the cutter bit to ensure positive retention and alignment along a rotational axis. The cutter bit is retained within a slot of the retainer component and the retainer component is coupled to a chuck component. The retainer component may be detachably attachable to the chuck component by external threads that are configured to thread into the internal threads of the chuck component. The cutter bit may be retained in the slot by a threaded retainer that extends through one side of the retainer component, through a cutter aperture in the cutter bit, through the slot and into a threaded retainer aperture in the opposing side of the retainer component.

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.
