Abstract

En borkrone (29) med faste skjære-elementer er forsynt med primære skjære-elementer (24) som er radialt adskilt fra hverandre over borkronens frontflate (25). Under boring bevirker spalten mellom skjære-elementene at det dannes en rygg (37) i bunnen av brannen, og toppen av ryggen fjernes far den når borkronens frontflate. Ved en utførelse av oppfinnel- sen består innretningen for å fjerne toppen i å anvende sidene av bæreorganene for de primære skjære- elementer.A fixed cutting element drill bit (29) is provided with primary cutting elements (24) radially spaced apart from each other over the front face (25) of the drill bit. During drilling, the gap between the cutting elements causes a ridge (37) to form at the bottom of the fire and the top of the ridge is removed if it reaches the front surface of the drill bit. In one embodiment of the invention, the device for removing the top consists of using the sides of the carriers for the primary cutting elements.
