ADC code | 537 |
Bit size | 12 1/4" (311.2mm) |
Tooth type | TCI Spherical Teeth |
Thread connections | According to API Spec7-1 standard |
API REG Pin | 6 5/8 Inch |
Material | Tungsten carbide insert, inlaid friction-reducing alloy |
Rotary speed | 100~60 rpm |
WOB | 0.4~0.8 KN/mm |
Cutting structure | The wear resistance of teeth is enhanced with premium tungsten carbide hardfacing on the tooth surfaces for steel tooth bit. The durability of premium tungsten carbide inserts is improved with new formulas and new techniques for insert bit. |
Gauge structure | Multiple gauge protection with gauge trimmers on the heel and gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hardfacing on the shirttail increase gauge holding capability and bearing life |
Jet Nozzles | Three nozzles |
Multiple gauge protection | Yes |
Product Application | It can receive higher WOB and faster rotary speed than conventional roller bearing bits. It is suitable for high RPM applications. |
Bearing Structure | Air cooling roller bearing package. Balls lock the conem, which reduces the probability of cone-dropping to the minimum. |
Quality management system | ISO 9001-2008 |
Formations | It is suitable for medium hard formations with high compressive strength, such as hard shale,limestone,sandstone,dolomite,etc.. |
Bit weight | 95kgs to 102.2 kgs |
