Zidutswa izi zimagwiritsidwa ntchito m'makina obowola ozungulira pa mapangidwe osweka, mapangidwe okhwima, mapangidwe apakatikati olimba, ndi malo opingasa. Zidutswa za cone imodzi zimachepetsa mwayi woti zitsime zipatuke.
• Zidutswa ziwiri za ma cone: Amagwiritsidwa ntchito makamaka pobowola mofewa komanso molunjika.
• Zidutswa za Ma Cone Atatu: Ma biti atatu a cone ndi mtundu wofala kwambiri wa biti, womwe umagwiritsidwa ntchito kwambiri pantchito zambiri zobowola padziko lonse lapansi.

Mabowo a Tricone drill akhoza kugawidwa m'magulu awiri:

i. Zidutswa za Tricone za Mano Odulidwa (MT Bits):

Ma MT bits oyambirira anali ndi ma cones awiri, pomwe mano ndi ma gullets pa ma cones sankakhudzana akamazungulira. Kukhudzana pakati pa mano pa ma cones oyandikana kumapereka kudziyeretsa, kumawonjezera kuchuluka kwa kulowa, komanso kumathandiza njira yoboola. Ma steel bits opukutidwa amagwiritsidwa ntchito m'mapangidwe ofewa mpaka apakati-olimba.

ii. Ma Drill Bits a Tungsten Carbide Insert (TCI):

Ma bits a Tungsten Carbide Insert (TCI), omwe amatchedwanso mabatani (monga mtundu wa MT), ali ndi ma cones ozungulira. Mosiyana ndi ma bits a MT, ma bits awa ali ndi mabatani a tungsten carbide pama cones pa kutentha kwakukulu kwambiri. Amagwiritsidwa ntchito pochita zinthu zolimba komanso zowononga m'malo osaya kwambiri pansi pa nthaka. Pakuya kwambiri, ma tricone bits sagwira ntchito bwino ndipo zimatenga nthawi kuti asinthidwe.

2. Ma Drill Bits Okhazikika Odulira

Zidutswa zodulira zokhazikika zimapangidwa ndi monolithic popanda ziwalo zosuntha. Ndipotu, mtundu uwu wa chinthu ulibe ma cone ozungulira okha; m'malo mwake, uli ndi thupi losasunthika la chinthu ndi mutu wokhazikika womwe umazungulira limodzi ndi chitoliro chobowolera ndi chingwe chobowolera. Thupi lalikulu la zidutswa zotere limapangidwa ndi chitsulo kapena tungsten carbide. Zidutswa za thupi lachitsulo zimakhala ndi kukana kwakukulu kukhudzidwa ndi mphamvu zomwe zimagwiritsidwa ntchito pa zodulira, koma chitsulo chimakhala ndi kukana kochepa kukhudzidwa ndi madzi obowolera. Mosiyana ndi zimenezi, zidutswa za thupi la tungsten carbide zimakhala ndi kukana kwakukulu kukhudzidwa koma sizimalimbana kwambiri ndi kugwedezeka.

i. Zidutswa Zodulira Zitsulo

Ma bits awa amagawidwa m'magulu awiri: zodulira zitsulo ndi ma bits a mchira wa nsomba, ndi ma bits odulira. Ma bits odulira amagwiritsidwa ntchito pobowola m'mapangidwe ofewa mumakampani amafuta ndi gasi. Ma bits odulira anali mtundu woyamba wa bits womwe umagwiritsidwa ntchito pobowola mozungulira, koma pang'onopang'ono adasinthidwa ndi ma cone bits chifukwa cha kusagwira bwino ntchito. Ma bits awa ali ndi zodulira zitsulo ndipo amagwiritsidwa ntchito kwambiri pobowola m'mapangidwe ofewa. Kuchuluka kwa momwe amagwiritsidwira ntchito kwachepa chifukwa cha kusagwira bwino ntchito m'mapangidwe olimba; pamene katundu wambiri agwiritsidwa ntchito pa bits, zodulira zitsulo zimalowa mu kapangidwe kake, ndipo kuwonjezeka kwa mphamvu ya pipe yobowola kungayambitse kuti pipe yobowola isweke ndikugwera m'chitsime. Mtundu uwu wa bits ndi wovuta kuwongolera njira yobowola bwino ndipo nthawi zambiri umapatuka pa njira yayikulu.

ii. Mabowo a Daimondi

Mu mtundu uwu wa chidutswa, tinthu ta diamondi timayikidwa m'thupi la chidutswa. Daimondi, chinthu chodziwika bwino kwambiri, imapangidwa ndi kaboni wokha. Chifukwa cha kuuma kwake, tinthu ta diamondi timakhala toyenera kwambiri kuboola m'mapangidwe olimba okhwima. Poyerekeza ndi tinthu todulira tozungulira ndi tinthu todulira tachitsulo, tinthu ta diamondi sitikhudzidwa kwambiri ndi matope oboola. Matope oboola osungunuka nthawi zambiri amawongolera magwiridwe antchito a tinthu ndipo ndi otsika mtengo.

Zidutswa za diamondi zimapereka ubwino wambiri, kuphatikizapo kukwera kwa liwiro la kubowola m'mapangidwe osiyanasiyana ndi miyala, kuchepa kwa nthawi yogwedera komanso kuwonongeka kwa zidutswa, kusakhala ndi chifukwa chogwiritsa ntchito zida zina, komanso kuyenerera kugwiritsa ntchito zitsime zodzaza ndi mphamvu komanso zinthu zina zapadera.
