Technical Data's of High & Medium Air Pressure DTH Button Bit:
About Us:
1. Deliver maximum energy to drilling bit, fast drilling speed and low air consumption due to the special inner structure of HD series DTH hammer designed according to newest rock drilling theory.
2. Smooth performance and long service lifeof HD series DTH hammer due to high quality alloy steel materials and advanced processing technology adapted.
3. Low problem rate and easy to maintenancedue to simple, reliable and easy assemble and disassemble inner structure of hammer.
4. Easy to depart bit from hammer due to multi- Head thread connecting chuck and cylinder of hammer.
5. Interchangeable with DTH bit and drill pipe.
