Abstract (en)

[origin: WO0205995A1] The drill bit (14) passes through a drilling bush (22) for guiding said drill bit. The drilling bush (22) is pressed against the workpiece (10). However, the drilling bush does not terminate flush with the workpiece, but comprises a linear supporting edge (28) that overlaps the apex of the curvature of the workpiece. This prevents the drilling bush from sliding off a curvature of the workpiece surface.
