Gradus extraho frenum est terebra frenum usus in formationibus mollibus uti solet ut arena, argilla, vel petra aliqua mollis.Tamen non bene operabuntur in formationibus grossis vel duris petrae.Usus includunt EXERCITATIO puteorum aquarum, fodienda, geothermal.environmentalem et explorationem exercendi.Cum fieri potest, gubernator foramina terebrare utendum est quia incisiones facillime ad stipitem efficiunt.
3 Alae gradus trahunt frenos unum fragmentum ex stannum ferro missum cum carbide tungsten incisis apicibus et latera coniecturam ut vitam longiorem curent.Habet 3 alas et 3 foramina rutilantia.Comparatus cum 4 alis, 3 alae gradum trahunt frena ad exercitio velocius et pugnax tendunt, cum vero breviores sunt diuturni et minus durabiles.3 Alae gradus stili trahunt frenos maiora incisuras vim producent quam chevron stilo trahunt frenum.Tabula gyratoria celeritas saepe frenos trahens debet esse inter 60 et 80 rpm cum levi pondere in frenum (WOB).
3 Alis gradus trahunt frena instrumenta oeconomica cum exercendis formationibus geologicis mollioribus et profundioribus profundioribus, principaliter designantur pro mollibus formationibus tomediis, ut Clay, Loam, Silt, Mostsoft-ad-media soils quae humorem habent, etc. Commendatur ad exercendam in Mining, Explorationis, Environmental, Aquae putei, Geo- lanus, etc.
