Isivuli sembobo se-PDC esingu-12 1/4 esinama-spiral blades kanye nezicucu zokusika ezingemuva

Lesi yi-spiral blades PDC hole opener, phezulu yi-6 5/8 API reg box, phansi yi-4 1/2 API reg box, ama-driller angangena ama-PDC bits noma ama-tricone bits asebenzayo enjini ngaphambili.

Incazelo Yomkhiqizo

Ama-blade amade e-PDC asebenza njengesiqinisi esicishe sibe yi-bit kanye ne-reamer egcina imigodi endleleni eqondile futhi i-ream igobe kahle udonga.
IFar Eastern ikhiqiza nesivuli semigodi se-PDC sohlelo lokusebenza lwe-HDD/No-Dig, sicela usithinte ukuze uthole ulwazi olwengeziwe.
