Construction Drilling

CENTER ROCK serves the global construction industry by designing, manufacturing, and distributing a complete line of air drilling tools and products including down-the-hole hammers & bits from 3.5”-48” (89–1219 mm) in diameter, LP® canister Rock drills and hole-openers (conventional and reverse circulation) from 24”-144” (610–3658 mm), ROTO LOC® underreamer systems for casing advancement, and other support equipment such as water injection systems, oil injection systems, air manifolds, and HYDRO-JAW® breakout/make-up systems.

Water Well Drilling

CENTER ROCK designs and manufactures down-the-hole hammers from 3.5”-22” (89-560 mm) and DTH button bits up to 48” (1219 mm) with various shanks, face styles, and carbide button configurations. For waterwell drillers, we offer 3 lines of hammers; the valveless CR line, the valved CENTER 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 rock drilling system, called ROTO LOC®, that drills and simultaneously advances casing.

Geothermal Drilling

Center Rock Inc. designs, manufactures, and services high performance down-the-hole percussion drilling tools, bits, and compression equipment for routine as well as challenging deep geothermal drilling projects.

Mining & Quarry Drilling

Hütte manufactures hydraulic drilling rigs for micropiles and ground anchors, for the enhancement of existing foundations, construction of new foundations, ground stabilization, and soil investigation. Hütte drilling rigs are highly flexible and compact, high performance, and engineered & manufactured with industry-leading stability and power. Hütte drilling rigs are well suited for difficult rock drilling conditions and in confined areas, which requires a particularly compact and mobile rig. Hütte has developed a field-proven drilling rig for micropiles, ground anchors and foundation construction, but also can be used for a variety of other drilling applications.

Utility Drilling

CENTER ROCK provides state-of-the-art drilling products to support the utility industry. Our mono-hammer utility pole drill offerings range from 3.5”-24” (89–610 mm) and include hex connection, side inlet swivel, and all ancillary items. Additionally, only CENTER ROCK offers Utility LP DRILL® canister style drills 18” (457 mm) and larger and HDD LP canister style drills 12” (305 mm) and larger. Multi-hammer canister style Utility LP Drills boast lightweight construction, low vibration and low air requirements which will ensure success in any drilling condition and are perfectly suited for mounting on any digger derrick unit.

Directional Drilling

Center Rock supports horizontal directional drilling (HDD) operations with down-the-hole hammers, bits, and LP canister drills built to handle rock conditions that slow down conventional HDD tooling. Our HDD LP canister drills, available 12″ (305 mm) and larger, deliver the power needed to advance through rock while keeping vibration and air requirements low. When the ground gets too hard for a standard HDD rig, Center Rock has the tooling to keep the bore moving.

Overburden Drilling

Center Rock’s ROTO LOC® underreamer system drills and simultaneously advances casing through overburden, ranging from 5-1/2″ to 36″ (140–914 mm), giving drillers a single system to get through loose or unstable ground and into competent rock. Paired with our DTH hammers and bits, ROTO LOC keeps the hole straight and the casing advancing without switching tools mid-run.
