Umehluko phakathi kwe-eccentric drill bit kanye ne-concentric drill bit:
I-1, ithuluzi lokumba ipayipi eligxilile ngenxa yodonga lwalo olungaphandle olushubile, ukwakhiwa kwembobo efanayo, umphumela wokudlulisa amandla awuhambisani nethuluzi lokumba eli-eccentric, ububanzi bembobo kuphela bukhulu, umphumela ungcono, kodwa izindleko zokukhiqiza zingcono kakhulu. ephakeme kakhulu kune-eccentric drilling ithuluzi;
2, i-eccentric pipe drilling ithuluzi hhayi kuphela ububanzi bembobo, nesakhiwo esilula, izindleko eziphansi zokukhiqiza, kulula ukuyisebenzisa, ngakho-ke selisetshenziswe kabanzi.
