2. Smooth performance and long service life of DTH hammer 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.
