Quarry & Dimension Stone Drilling
Quarries and dimension stone operations need compact, mobile rigs that drill accurate holes at the right diameter. Two PRD rigs cover the job: DTH for larger blast holes, top hammer for small, short holes.

Top hammer drilling places the hammer at the top of the drill string; it is quick for small-diameter, short holes. DTH places it behind the bit at the bottom of the hole for larger holes to depth.
