Tricone Rock Drill Bits:
Dan moulen an (dan asye) Bits tricone perçage pou fòmasyon mou wòch mwayen.
Fòmasyon mou moulen dan tricone Bits yo itilize fè egzèsis fòs konpresiv ki ba, fòmasyon mou.Longè pwojeksyon dan yo itilize sou gwo kòn konpanse pou bay pi gwo pousantaj pénétration posib.Mete rezistans difisil fè fas a itilize kontwole mete dan.Sou kalite ki pi mou sa a difisil fè fas a konplètman kouvri dan yo ti jan.
Mwayen fòmasyon freze dan tricone Bits yo itilize fè egzèsis segondè fòs konpresiv, fòmasyon mwayen wòch.Dan pwojeksyon tire ak longè krèt redwi yo itilize nan seri sa a nan desen ti jan.Dirab fè fas a difisil aplike pou diminye mete dan.
