Our Ring Bit systems are based on Spiral Flush technology. It is a perfect solution for Over-burden-drilling in complex ground conditions. To be able to utilize DTH technology in urban and environmentally sensitive areas the air used in drilling should not escape to the surroundings. Patented Spiral Flush technology is a ground breaking solution to control air in DTH applications. All air is directed crosswise and there are no air channels forward to the drilled ground.
1) Pressurized air over drills material. Over drilling removes more material than anticipated changing ground’s original characteristics hazarding nearby structures.
2) Air that is blown forward travels long distances in loose ground or soft clay. This can cause severe damages in nearby buildings and structures.
