DTH Hammer Advatages
1. Fast drilling speed and low air consumption due to the special inner structure.
2. Smooth performance and long service due to high quality alloy steel materials and advanced processing technology adapted.
3. Low problem rate and easy to maintenance due 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
