Tegirmonli tishli Tricone rock matkap uchlari:
Tegirmonli tish (po'lat tish) tricone bitlari yumshoq va o'rta tosh shakllanishi uchun burg'ulash.
Yumshoq shaklli frezalangan tish tricon bitlari past bosim kuchi, yumshoq shakllanishni burg'ulash uchun ishlatiladi.Mumkin bo'lgan eng katta kirish tezligini ta'minlash uchun yuqori ofset konuslarida uzun proektsiyali tish uzunliklari qo'llaniladi.Aşınmaya qarshilik qattiq qoplama tish aşınmasını nazorat qilish uchun ishlatiladi.Eng yumshoq bit turlarida bu qattiq qoplama bit tishlarini to'liq qoplaydi.
O'rta shaklli frezalangan tish tricon bitlari yuqori bosim kuchi, o'rta tosh shakllanishini burg'ulash uchun ishlatiladi.Ushbu bit konstruksiyalari seriyasida cho'qqi uzunligi qisqartirilgan otish proyeksiyasi tishlari qo'llaniladi.Tish aşınmasını kamaytirish uchun bardoshli qattiq qoplama qo'llaniladi.
