Center Rock’s new HDD-LP Pull Reamer drills the hardest rock formations. Powered by individual LP hammers packaged within the reamer canister, each hammer is pneumatically powered by compressed air supplied through the drill pipe. The rock is pulverized and the cuttings are then forced back through the annular area between the pilot hole and drill pipe by the supplied air.
