Merafong e tebileng, li-cutters tsa PDC, tse sebetsang ka majoe a thata a kang granite le basalt, li bonts'a sekhahla sa ho apara se lekanang le karolo ea bohlano feela ea li-carbide cutters, ho lelefatsa bophelo ba bona ba tšebeletso ka makhetlo a 3-5.

Mabapi le ho ikamahanya le maemo, ho feto-fetoha ha li-cutters tsa PDC ho kopana le litlhoko tse fapaneng tsa ho ntšoa ha lisebelisoa. Ha ho chekoa oli le khase, likarolo tsa tsona tse hlabang li pshatla mafika ka potlako.

Ho latela pono ea indasteri, li-cutters tsa PDC li kentse letsoho ka kotloloho ho phokotso ea litšenyehelo le ntlafatsong ea ts'ebetso ea ts'ebeliso ea lisebelisoa.
