    Advantages:

    Our DTH hammer and bits has following advantages:

    Deliver maximum energy to drilling bit, fast drilling speed and low air consumption due to inner structure of DTH hammer designed according to newest rock drilling theory.

    Smooth performance and long service life of DTH hammer due to high quality alloy steel materials and advanced
    processing technology adapted.

    Low problem rate and easy to maintenance due to simple , reliable and easy assemble and disassemble inner structure of hammer.

    Easy to depart bit from hammer due to multi-head thread connecting chuck and cylinder of hammer.
