Birta Ilkaha Rotary Drill Bit
Tricone bit waa qalab muhiim u ah qodista saliidda, waxqabadkeeda shaqadu waxay si toos ah u saameyn doontaa tayada qodista, hufnaanta qodista iyo kharashka qodista.Qodista saliida iyo qodista juqraafiyeed waa inta ugu badan ee la isticmaalo ama birta kolayga.Qaniinyada kolayga ayaa raad ku leh ruxidda, burburinta iyo xiirida dhagaxa samaynta ee wareegta ah, sidaas awgeed qaniinyada kolayga ayaa la qabsan karaa lakabyo jilicsan, dhexdhexaad ah iyo kuwo adag.Gaar ahaan in yar kolayga jet iyo nozzle dheer ka dib markii ay soo ifbaxa of kolayba, xawaaraha qodista kolayga si weyn u soo hagaagtay, waa taariikhda horumarinta kolay xoogaa kacaanka weyn.Qaniinyada kolayga waxa loo qaybin karaa ilig (ilkaha) nooca iligga, ilig (bit) (ilkaha lagu dhejiyay ilkaha carbide) qaniinyada kolayga;iyadoo loo eegayo tirada ilkuhu waxa loo qaybin karaa koor qudha, labanlaaban, Saddex-koor iyo kooto badan.Dal iyo dibadba waxa ugu badan laga isticmaalo, ta ugu badan waa Tricone bit.
