1.Koupe Estrikti nan kalite sa a sele ak ki pa sele twa kòn Bits:
Se mete-rezistans nan dan ranfòse ak carbure tengstèn prim fè fas a difisil sou sifas dan yo pou ti jan an asye.
2.Gauge Estrikti nan kalite sa a twa moso wòch kòn:
Pwoteksyon kalib miltip ak tayaj kalib sou talon an ak foure kalib sou sifas la kalib nan kòn lan, foure carbure tengstèn ak fè fas a difisil sou shirttail la ogmante kapasite kenbe kalib ak lavi pote.
3.Bearing estrikti sa a kalite twa kòn wòch Bits:
Segondè presizyon woulo bi ak de figi pouse.Boul fèmen kòn lan. Poussée fè fas a fas difisil ak alyaj ki reziste mete.Yo amelyore rezistans fwotman ak rezistans kriz nan portant la
