Tricone bit/Roller konusli bit bozorda ko'p qirrali matkap uchidir.Konusning soniga ko'ra, uni bitta konusli bit, tricone bit va yig'ilgan ko'p konusli bitga bo'lish mumkin.
TCI Tricone bitlari o'rta va qattiq jinslarning shakllanishi uchun burg'ulash.
O'rta shaklli TCI tricone bitlarida tovon qatorlari va ichki qatorlardagi agressiv chisel volfram karbid qo'shimchalari mavjud.
Ushbu dizayn o'rta va o'rta qattiq qatlamlarda tez burg'ulash tezligini va qo'shimcha kesish strukturasining chidamliligini ta'minlaydi.HSN kauchuk O-ring rulmanning chidamliligi uchun etarli darajada muhrlanishni ta'minlaydi.
Qattiq shakldagi TCI tricone bitlari qattiq va abraziv qatlamlarni burg'ulash uchun ishlatilishi mumkin.Aşınmaga chidamli volfram karbid qo'shimchalari bit o'lchagichni yo'qotmaslik uchun tashqi qatorlarda qo'llaniladi.To'sarning chidamliligi va uzoq umrini ta'minlash uchun barcha qatorlarda yarim sharsimon shakldagi qo'shimchalarning maksimal soni qo'llaniladi.
