Preferably, the two independent components only form a coupling point when installed. Preferably, the first component is designed as a first cardboard element. Preferably, the second component is designed as a further cardboard element. Preferably, the first component and the second component are designed to match one another.

[0008] The drill packaging device preferably has at least a first cardboard element and at least one further cardboard element. In this context, a “cardboard element” is to be understood in particular as a flat element which is designed to at least substantially partially enclose a drilling tool. A “flat element” is to be understood in particular as an element which, in a laid-out state, has a vertical extent which is many times smaller than a longitudinal extent and a transverse extent of the element.

The drill bit packaging device is preferably designed to accommodate the drill bit in the recess in an opaque manner. A customer cannot see a drill bit arranged in the recess from the outside, particularly when the drill bit packaging device is unopened.This can provide particularly advantageous protection of the drill against external influences.

Preferably, at least two physical parameters, in particular a humidity, preferably a water content, and a temperature, of the further cardboard element are specifically changed or adjusted by the preconditioning before forming. It is also conceivable that a number of physical parameters of the further cardboard element other than two is specifically changed or adjusted by the preconditioning.

Alternatively, a partial application of the coating to a contact surface between the first cardboard element and the further cardboard element is also conceivable.

[0025] The fact that at least one first element is “connected” to at least one further element should be understood in particular to mean that the first element is advantageously connected to the further element via at least one frictional connection and / or at least one positive connection, for example via a rivet and / or snap-in connection and / or a tongue and groove connection and / or a clamping connection and / or another connection that appears appropriate to a person skilled in the art, and / or is integrally connected to the further element, for example by a welding process, an adhesive process, an injection-molding process and / or another process that appears appropriate to a person skilled in the art. Preferably, the first cardboard element and the further cardboard element are at least substantially non-detachably connected to one another."At least substantially indetachable" is understood here to mean, in particular, a connection of at least two elements that can only be separated from one another with the aid of separating tools, such as a saw, in particular a mechanical saw, etc., and / or chemical separating agents, such as solvents, etc. Alternatively, a force-fitting and / or form-fitting connection between the first and the further cardboard element is also conceivable. "Force-fitting and / or form-fitting connection" is understood here to mean, in particular, a detachable connection, wherein a holding force between two components is preferably transmitted by a geometric engagement of the components with one another and / or a frictional force between the components.
