Gemaalde tooth Tricone Rock Drill Bits:
De gemalen tosk (stalen tosk) tricone bits boarjen foar sêfte oant medium rotsformaasje.
De sêfte formaasje gemalen tooth tricone bits wurde brûkt om boarje lege compressive sterkte, sêfte formaasje.Lange projeksje toskenlangen wurde brûkt op hege offsetkegels om de grutste mooglike penetraasjes te leverjen.Slijtweerstand hurde facing wurdt brûkt om te kontrolearjen tosk wear.Op de sêftste bittypen bedekt dizze hurde bekleding de bittosken folslein.
De medium formaasje gemalen tooth tricone bits wurde brûkt om te boarjen hege compressive sterkte, medium rock formaasje.Shoot projeksje tosken mei fermindere crest lingte wurde brûkt yn dizze rige fan bit designs.Duorsume hurde facing wurdt tapast om toskwear te ferminderjen.
