IADC-MATATU DIGITS
| FIRST DIGIT | CHECHIPIRI DIGIT | YECHITATU DIGIT | ||||
| KUBVA 1-8 Nhamba yepamusoro inoreva kuwedzera mazino ekuumbwa kwakaoma | KUBVA 1-4 | KUBVA 1 ~ 7 Iyi manhamba inoisa mabheti zvinoenderana neanobata / chisimbiso mhando uye yakakosha geji yekudzivirira kupfeka sevamwe | ||||
| 1
| SIMBA NEZINO ZVINORUMWA /MILLED TOOTH BITS | Yakapfava maumbirwo ane yakaderera compressive simba uye yakakwirira drilling kugona | 1,2,3,4 inobatsira kuenderera mberi nekupwanya kuumbwa kwepasi pevhu 1 ariye akapfava uye 4 akanyanya kuoma. | 1 | Open bearing/ Non-sealed bearing | Standard open bearing roller bits |
| 2 | MILLED TOOTH BITS | Maumbirwo akaomarara epakati nepakati ane simba rekumanikidza | 2 | Yakajairika yakavhurika bhiti yekuchera mhepo chete, mabhiti etricone ekuchera zvakanaka. | ||
| 3 | MILLED TOOTH BITS | Yakaoma semi-abrasive uye abrasive maumbirwo | 3 | Yakazaruka yakazaruka bhiti ine geji dziviriro inotsanangurwa seinoisa carbide muchitsitsinho chekoni. | ||
| 4 | TUNGSTEN CABIDE INSERTED BITS /TCI BITS | Akapfava maumbirwo ane yakaderera compressive simba uye yakakwirira kudhiraivha kugona | 4 | Yakaiswa chisimbiso | Roller yakavharwa fani | |
| 5 | TCI BITS | Yakapfava kusvika Pakati pemaumbirwo ane yakaderera compressive simba | 5 | Roller yakavharwa kutakura ine carbide inoisa muchitsitsinho chekoni. | ||
| 6 | TCI BITS | Maumbirwo akaoma epakati ane simba rekumanikidza | 6 | Journal yakavharwa mabhiti ekubereka | ||
| 7 | TCI BITS | Yakaoma semi-abrasive uye abrasive maumbirwo | 7 | Journal yakavharwa mabheti ane carbide inoiswa muchitsitsinho chekoni. | ||
| 8 | TCI BITS | Zvakanyanya kuoma uye abrasive formations | ||||
