Abstract

The present invention relates to a holder for a number of drills, which can advantageously be used for coating drill tips. The holders according to the invention make it possible to arrange the drills in the coating unit in such a way that their tips rest on a cylindrical wall and these can be rotated past a coating source at the same minimum distance. The holder comprises a first curved wall with holes, a second curved wall with holes or slits and a third wall which serves as stop for drills inserted in the holes of the first and second wall.
