Advantages:

• YN30A handhold internal-combustion rockdrill is a hand-rockdrilling tool which integrates the small gasoline-engine,compressor and rockdrill.
• It can blow off the rock powder in the blasthole by the compressing air generatedfrom itself.
• Just30kg weight for the main engine .
  Easy to carry about.
  Applicable for the areas of high mountains and ofwithout power and wind pressure equipment,especially for those temporary projects with frequent movement.
• Working on the rocks,available for vertical down drilling,horizontal drilling and up drilling with the angle of less than 45°.The max. vertical down drilling depth can be 6m.

Applications:
1. Applicable for rock drilling.if replace a few of the parts,it can also be used as a breaker and a rammer for various work of breaking,shovelling, excavating,splitting and ramming,etc.
