Specifications

dth drill rig anhammer:
1.efficient energy transfer
2.faster drilling speed
3.lower oil consumption
4.longer life

 

 

DTH drill rig, blast hole drill rig, dth hammer:

 

1. 10 years manufacturing experience;

2. Certificate: ISO9001:2008

3. Material: Carbide

 

 

It has the following advantages:

1. Valveless air distribution. More reliable.
2. Simple design of the piston, long life.
3. More efficient energy transfer, faster drilling speed, lower air consumption and lower oil consumption.
4. Fewer internal parts, simple structure, longer life, less failure and easier to maintain because all the parts are heat treated.
5. Easy to disassemble because the top sub, the drive chuck and the external cylinder are connected by multi-step thread.
