Mapangidwe Ofewa a TCI trione bits:
Mapangidwe ofewa a TCI trione bits amagwiritsidwa ntchito kubowola mphamvu zochepa zopondereza, zofewa kwambiri.Kang'ono kakang'ono kameneka kanagwiritsidwa ntchito kwambiri ndi ma conical ndi tchisel tungsten carbide okhala ndi mainchesi akulu komanso mawonekedwe apamwamba.Kapangidwe kamangidwe kameneka kameneka, kaphatikizidwe ndi kuchuluka kwa ma cone offset, kumabweretsa mitengo yolowera kwambiri.Mizere yozama ya mizere yocheka imalepheretsa kuti pang'onopang'ono pakhale zomata.
Mapangidwe apakatikati a TCI trione bits:
Mapangidwe apakatikati a TCI tricone bits amakhala ndi zoyika zachisel tungsten carbide pamizere ya chidendene ndi mizere yamkati.Kapangidwe kameneka kamapereka chiwongolero chobowola mwachangu ndikuwonjezera kulimba kwa kapangidwe kake pakati mpaka pakati pazovuta zama ations.HSN rabara O-ring imapereka chisindikizo chokwanira kuti chikhale cholimba.
Mapangidwe Olimba a TCI trione bits:
Mapangidwe olimba a TCI tricone bits atha kugwiritsidwa ntchito kubowola zolimba komanso zowononga.Valani zoyikapo za tungsten carbide zimagwiritsidwa ntchito m'mizere yakunja kuti mupewe kuwonongeka kwa bit gauge.Ziwerengero zochulukirapo za zoyikapo zowoneka ngati hemispherical zimagwiritsidwa ntchito m'mizere yonse kuti zikhale zolimba komanso moyo wautali.
