XY-6B is a mechanical transmit and hydraulic feeding spindle core drilling machine. Hydraulic chuck and automatic centring manual chuck are assembled on the spindle, and the hoist is equipped with water brake. XY-6B is mainly used for large-hole core drilling with diamond bits for exploration of the solid mineral deposits, as well as for the exploration of shallow oil and gas.
1 Appropriate rang of rotation speeds to satisfy the varied demands of drilling.
2 Suitable for large diameter core drilling.
3 Easy to disassemble and transport.
4 Easy to operate and maintain.
6 Diesel engine or motor equipped as required.
