Abstract
Le trépan comprend des pointes en métal dur disposées de manière à avoir des directions différentes par rapport à une surface frontale bombée. Suivant l'invention, la totalité de la surface frontale est divisée irrégulièrement en proéminences 14 portant sur leurs sommets 15 des pointes en métal dur 16, et entre les différentes proéminences qui se fondent les unes dans les autres se trouvent des dépressions qui les limitent. Le trépan est en particulier destiné à perforer des roches abrasives, par exemple le quartz.
