Waterwell Drilling & Geothermal

Center Rock Inc. designs and manufactures DTH hammers from 3.5″ to 22″ (89mm – 560mm) and DTH button bits up to 48″ (1219mm) with various shanks, face styles, and carbide button configurations. For waterwell drilling, we offer 3 lines of hammers; the valveless CR line, the valved Rock Force (RF) (both utilize QL shank bits), and the Rock Xtreme (RX) line. The RX offering is the newest, valved, high frequency hammer developed by Center Rock with it’s own bit shank design and no blow tube. Center Rock has also designed a unique underreamer overburden drilling system, called ROTO LOC®, that drills and simultaneously advances casing.
