Advantages of Quarry rock stone mining drill hammer:
1. More efficient energy transfer.
2. Faster drilling speed, 15%-30% higher than others.
3. Lower air consumption and lower oil consumption. oil consumption is about 10% lower than others
4. Direct factory price. Advantages of dth hammer spare parts :
1.Valveless air distribution. More reliable.
2.Simple design of the piston, long life.
3.Fewer internal parts, simple structure, longer life, less failure and easier to maintain because all the parts are heat treated.
4.Easy to disassemble because the top sub, the drive chuck and the external cylinder are connected by multi-step thread.
