Recommended Maximum Air Pressure for Stratex Drill Systems

The maximum recommended air pressure for Stratex drilling with down-hole hammers is 12 bar, which equals 210 psi.

Rotation speed depends on the size of the Stratex bit and also on the formation being drilled. The rotation speed may have to be varied as the formation changes. The table shows recommended rotation speeds for the various Stratex sizes.
