Ngenxa yeemfuno ezahlukeneyo zemilo, ukucaciswa, ukuchaneka, kunye neendlela zokucubungula imingxuma, kukho iintlobo ezininzi zezixhobo zokusika ze-machining yemingxuma.

I-drill yeziko isetyenziselwa ukulungiswa kwangaphambili kunye nokubeka indawo echanekileyo yokulungiswa komngxuma, ukukhokela i-Fried Dough Twists drill ukucubungula imingxuma kunye nokunciphisa iimpazamo. Ukuba umngxuma ophakathi awugrunjwanga, kuya kubakho ukutenxa xa kusetyenzwa ngokuthe ngqo.

I-Fried Dough Twists drill ibizwa ngokuba yi-spiral chip groove, efana neFried Dough Twists. I-Fried Dough Twists drill sesona sixhobo sisetyenziswa ngokuxhaphakileyo sokulungisa umngxuma, esisetyenziselwa ukusetyenzwa kwemingxuma eyenziwe ngentsimbi engenasici, ingxubevange yobhedu yetitanium kunye nezinye izinto.

I-deep hole drill luhlobo lwe-drill esetyenziselwa ngokukodwa ukucubungula i-drill yemingxuma enzulu, enokuthi ihlulwe ibe yinto ekhutshwayo yangaphandle nangaphakathi.

Ubunzima bokutshatyalaliswa kobushushu kunye nokukhupha amanzi ngexesha lokugrumba umngxuma onzulu, kunye nokungahambi kakuhle ngenxa yombhobho we-drill slender, kunokubangela ukugoba kunye nokungcangcazela ngokulula.Ngokuqhelekileyo, iinkqubo zokupholisa uxinzelelo zisetyenziselwa ukusombulula iingxaki zokupholisa kunye nokukhupha amanzi.

I-Countersink drill, ekwabizwa ngokuba yi-spot facer, luhlobo lwe-drill bit enomatshini ekujoliswe kuwo.

Indlela yokuqhuba yesiNtu kukuqala ngokugrumba imingxuma ephantsi ngentwana eqhelekileyo yokomba, kwaye emva koko usebenzise i-countersunk drill ukugrumba imingxuma engekho nzulu ngaphezulu.

I-inclined cutting edge ye-flat drill inikezela ngokukhawuleza kwaye icocekile ukusika, kunye namanqaku okugaya achanekileyo anokuphucula ukuchaneka, kodwa ukusika kunye nokusebenza kwamanzi akubi.

Ukuseta i-drill, ekwabizwa ngokuba yi-hollow drill drill, njengoko igama libonisa, yintwana yokubhola engenawo undoqo wokuqhuba,

Inokufaka umngxuma owandisiweyo isixhobo somatshini kumngxuma ongaphakathi owombiweyo.

Xa kusetyenzwa imingxuma enzulu enobubanzi bomngxuma ongaphakathi ongaphezulu kwe-150 millimeters, indlela yokwemba indlwane isoloko isetyenziswa.

Umzimba we-drill bit uxhotyiswe ngeebhloko zesikhokelo ukuthintela ukungcangcazela kunye nokuphambuka komngxuma wokusika ngexesha lokusika. Iibhloko zesikhokelo zenziwe ngezinto ezinganxibiyo ezifana ne-alloy eqinile, umthi werabha, okanye inayiloni.
