Tapered drill midziyo inopawo hexagonal chuck chikamu kuti ipe mukana wekutenderera chuck bushing, iyo inowanzove ine forged collar kuchengetedza chaiyo shank inorova kumeso chinzvimbo mudombo rekudhirowa, uye kuenzanisa tapered bit pamucheto wesokisi. Makomba anowanzo kucherwa mu 0.6 m increments kuti agare kureba kwemhepo-yegumbo rekudya. Nekupinda kwakakwira, maburi akatwasuka, hupenyu hurefu hwesevhisi uye mutengo wakaderera pamita imwe yakadhirowa pane inosanganisirwa simbi, tapered drill midziyo iri kutora chikamu chemusika kubva kune yakakosha dhiri simbi, kunyanya mumashandisirwo emigodhi uye dimensional dombo indasitiri.
Maumbirwo akasiyana ematombo uye madhiri ematombo anoda akasiyana taper angles. Pakuchera zvine high impact hydraulic rock drills mukati-yakaoma kusvika kune yakaoma uye abrasive rock formations, yakafara taper angle inowanzoshandiswa. Taper angles ye11 ° uye 12 ° anowanzo shandiswa pane zvemazuva ano zviboorero. Kune zvibooreso zvedombo zvakaderera uye akapfava maumbirwo ematombo, yakamanikana taper angle ye7° inoshandiswa. A 7° angle inogona zvakare kushandiswa kana bit kuruka iri dambudziko paunenge uchishandisa 11° uye 12° midziyo. Pamusoro pezvo, kona ye4.8°(zvakare 4°46’) yakanakira dombo rakapfava paunenge uchishandisa pneumatic kana hydraulic drill rigs - kudzivirira mabits kubva kutenderera kana kuvharika. Tsvimbo imwe chete inoshandiswa kuchera makomba mapfupi (≤2.0m), nepo matanda ari munhevedzano anoshandiswa kuchera makomba akadzika (kusvika 2.0m), kudzivirira kukotama kushushikana zvakanyanya.
Plato tapered drill rods inouya nemagiredhi matatu, uye kureba kunowanikwa kubva pa600mm (2') kusvika 11,200mm (36'8”), (yakayerwa kubva pakora kusvika kumagumo akatemerwa).
Taper Rods Magiredhi Anokurudzirwa Tafura:
| MaGrades | Types | Zvinokurudzirwa mamiriro |
| Superior | G III, T III, | 1) Rock drills inokanganisa simba: ≥76J, kazhinji modhi: YT28 2) Kudzika kwekuchera: ≥ 2.5 m (8’ 2 27/64”) 3) Maumbirwo edombo: yakaoma kwazvo, yakaoma, yepakati yakaoma uye yakapfava dombo Protodyakonov Hurema Chikero: f ≥ 15 Uniaxial Compressive Strength: ≥150 Mpa 4) Kutsiva: G tsvimbo, G I tsvimbo, ROK |
| Normal | G I, ROK | 1) Rock drills inokanganisa simba: ＜ 76 J, kazhinji modhi: YT24 2) Kudzika kwekuchera: ≤2.5 m (8’ 2 27/64”) 3) Maumbirwo edombo: Medium hard and soft rock Protodyakonov Hurema Chikero: f ＜15 Uniaxial Compressive Strength: ＜150 Mpa 4) Kutsiva: G tsvimbo |
| Economy | G | 1) Rock drills inokanganisa simba: ＜ 76 J, kazhinji modhi: YT24 2) Kudzika kwekuchera: ≤2.5 m (8’ 2 27/64”) 3) Maumbirwo edombo: Medium hard and soft rock Protodyakonov Hurema Chikero: f ＜10 Uniaxial Compressive Strength: ＜100 Mpa |
Specification Overview:
| Rod Kureba | Taper Degree | ||
| Shank Style | mm | tsoka/inch | |
| Hex22 × 108mm | 500 ~ 8,000 | 1’ 8” ~ 26’ 2” | 7°, 11° and 12° |
| Hex25 × 108mm | 1500 ~ 4,000 | 4'11" ~ 13'1" | 7° |

Notes:
1.Yakajairika yekubatanidza taper dhigirii ndeye 7 °, 11 ° uye 12 °, mamwe madhigirii akafanana 4.8 °, 6 ° uye 9 ° anowanikwawo pakukumbira;
2.Shank yakajairwa ndeye Hex22 × 108mm, Hex25 × 159mm uye mamwe masitayera aripowo kana pane chikumbiro chevatengi;
3.Kureba kwetsvimbo kunofanirwa kutsanangurwa mukurongeka;
4.Kuti uenderane nemamiriro akasiyana-siyana ematombo, drill rod inosarudzwa nevashandisi.
