Abstract
En kutteinnsats (20) for anvendelse på et metallkuttende verktøy (10) nede i brønnhullet i en olje- eller gassbrønn, med minst én landflate (22) på en ytterkant av innsatsen, og minst én skråflate (24) anordnet i vinkel i forhold til innsatsens akse og som hever seg opp over den tilstøtende landflate i bevegelsesretningen for innsatsen. Flere skråflater og landflater kan anvendes på hver innsats og flere innsatser kan anvendes på hvert verktøy.
