I-Rotary Bit yoKugrunjwa kwe-Blest Hole
IVenkile ye-Drill ithatha izibonelelo zetekhnoloji yoyilo lwamva nje kunye neenkqubo zokwenziwa kwezixhobo zethu zokusika iirola, ezisetyenziselwa ukunyusa ukudika, ishaft ekruqulayo kunye nokubuyisela umva ukomba ojikelezayo.
Abasiki basebenzisa i-roller-ball-roller-bearing configurations.Ibhola yePremium, iibheringi eziqengqelekayo kunye negrisi yobunikazi kubomi be-creasebearing kunye nomthamo, okhokelela kubomi obuninzi bokukhonza babasiki.Izitywini zethu zobuso beMetal zisebenzisa imathiriyeli yokuthengisa.Ezi zitywina zobuso be-Metal ziye zangqina ukuba ziya kuthwala ubomi ngokukhula ngokuchasene nabo sikhuphisana nabo kwiimeko ezinzima kunye neemeko ezinzima zokomba.
