Title
(EN) DEVICE FOR DETACHING AT LEAST ONE BURR FROM AN OPENING OF AT LEAST ONE TRANSVERSE BORE-HOLE OF A WORKPIECE, DRILLING STATION HAVING THE DEVICE AND METHOD FOR DETACHING THE AT LEAST ONE BURR USING THE DRILLING STATION
Abstract
(EN)

A device for detaching a burr from an opening of a transverse borehole of a workpiece includes an elongate shank for positioning in a longitudinal borehole of the workpiece and a fillet to avoid the elongate shank colliding with a drill for drilling the transverse borehole. In an example embodiment, the device has an aperture to further avoid the elongate shank colliding with the drill. In an example embodiment, the elongate shank has a cutting section with a cutting edge for detaching the burr from the opening of the transverse borehole.
