Kelly drilling is one of the most common and popular types of drilling, and every operator should be familiar with this method and drill rig type. It utilizes dry rotary drilling to break through hard ground and rock and can bore to considerable depths and diameters.
Continuous Flight Auger (CFA) Drilling is another popular method that utilizes continuous drilling to displace the earth. This is the best method for pre-drilling holes, as the auger must match the depth of the hole it is drilling.

Displacement drilling is used for cast-in-place piles where the earth is displaced without bringing any to the surface, and a smooth casing is driven into the ground and fitted with a displacement body on the lower end.
If you need help determining which method will work best for your project, you should work with engineering teams and examine professional geotechnical analyses before breaking ground to avoid damaging equipment, which can result in harm to crews in the field and costly downtime.
