HOW IT WORKS

Center Rock Inc.’s new HDD LP DRILL is a product that has evolved after many years of success with our LP product line. The LP product line has proven to be very efficient in drilling the hardest rock formations around the world. The drilling markets that have utilized this technology are oil & gas, foundation, mine ventilation/dewatering and mine rescue. Now, we are proud to introduce this product into the HDD market.

The HDD LP DRILL is powered by individual LP hammers packaged within the reamer canister. Each of these hammers is pneumatically powered by compressed air supplied through the drill pipe. Each hammer impacts its respective bit which pulverizes the rock into small chips/cuttings. These cuttings are then forced back through the annular area between the pilot hole and drill pipe by the supplied air.
