Set of panels

A set of panels comprising:

• a first panel and a second panel, wherein the first panel comprises a first edge, a first panel surface and a second opposite panel surface, and wherein the second panel comprises a second edge, a third panel surface and an opposite fourth panel surface,
• wherein the first edge comprises a locking strip with a locking element configured to cooperate with a locking groove at the second edge of the second panel for locking the first edge to the second edge in a first direction which is parallel to the first panel surface,
• wherein the first edge is configured to be assembled to the second edge by a displacement of the second edge relative the first edge in an assembly direction, which is perpendicular to the first panel surface, to obtain a locked position of the first edge and the second edge,
• wherein the locking element comprises a first locking surface at a first angle from a first plane parallel to the first panel surface and the locking groove comprises a second locking surface at a second angle from a second plane parallel to the third panel surface,
• wherein the first angle is different from the second angle such that the first locking surface converges towards the second locking surface at a cooperation part in the locked position, and the first locking surface cooperates with the second locking surface at the cooperation part for the locking in the first direction,
• wherein the locking element comprises a first guiding surface and the locking groove comprises a second guiding surface at an opening of the locking groove, wherein the first guiding surface is configured to cooperate with the second guiding surface during assembling to guide the locking element into the locking groove,
• wherein a transition surface between the first locking surface and a strip surface of the locking strip has a rounded shape with a transition radius, and wherein the transition radius is greater than a radius of the second guiding surface.
