Abstract

Et borskjær inkluderer en hoveddel som har en fremre flate og en sideflate, hvor sideflaten inkluderer en skulder nedenfor den fremre flate og strekker seg hovedsakelig vinkelrett på en sentral akse i hoveddelen, og en ring som er hardere enn hoveddelen, innfestet til hoveddelen ved en fremre flate av skulderen. Brukstid for borskjæret økes ved å opprettholde bestemte dimensjonsrelasjoner med hensyn på posisjonen av ringen på hoveddelen, og diameteren av partier av hoveddelen.
