Model Number

YN30A

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 6cm.
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.

2. Wide applicability. Regardless of the high mountains,flat grounds, extremely the hot area with the temperature of + 40ºC and bitter cold area of -40ºC,it can work in good condition.
