P&Q University Lesson 4: Drilling & Blasting

Air-operated drifter drills generally use air at pressures of about 100 to 125 psig (690 kPa to 862 kPa). To use higher pressures causes excessive wear and breakage of the drilling accessories. Hydraulic-operated drifters employ similar principles of operation, except that hydraulic fluid is relatively non-compressible.
