6 3/4″IADC 642 645

tricone bits are the most widely used drill bits and are suitable for a variety of formations from soft to hard. The tricone bit has low torque when breaking rock, rotates smoothly, and causes little harm to drilling tools and ground equipment: the working edge is longer than that of a scraper bit, which reduces wear and extends the service life.   IADC Code:412/415/642/ 645/542/545 RODUCT SPECIFICATION OPERATING SUGGESTIONS Bearing Type:Roller-Ball-Roller- Thrust Button/Sealed Bearing Circulation Type:Jet Air Cutting Structure inner and Nose Rows:Conical -Gage Rows:Conical Gage Bevel Protection:Round Pin Connection:4 1/2"APIMetric Bit Diameter:200mm Product Weight:34KG Weight on Bit:15,750-39.380lbs Air Back Pressure:0.2-0.4MPa Rotary Speed:110-80RPM
