RotaHam Series

RotaHam Series
A Versatile drill with a combination of both Direct Rotary and DTH Technologies.
   
COMBINATION RIGS.
Rotary-cum-percussion is the combination method of percussion and rotary drill. It is not practicable to put one drill for one operation and get another drill for second operation. Combination drill is used so that any drilling operations can be done depending upon the condition of the site. These drills are used generally for alluvial formation comprising boulder rocks.
