HENGJI BIT SPECIFICATION | |
Bit Size | 6 1/8'' |
IADC Code | 537 |
Series | HR |
Tooth type | TCI/tungsten carbide insert |
Connection | 3 1/2 API REG PIN |
Bearing | rubber sealed bearing |
Nozzle | three jet nozzles |
Rotary Speed(rpm) | 120~50 |
Weight on Bit(KN/MM) | 0.45~1.0 |
Application | water well,oil well,HDD,exploration,etc |
Formation | Soft to medium formations |
HR Series Rubber Sealed Bearing Bits have a journal bearing with a hardfaced head bearing surface. The inner hole of the cone is coated with silver. This improves the bearing's load capacity and resistance to seizure. The O-ring seal is made of high saturated buna-N, which is more resistant to wear. The seal section has been increased and a precisely designed sealing flange has been added in the cone sealing area to enhance the seal's reliability.
