Ditch Witch All Terrain Air Hammer

July 25, 2011

Designed to work with Ditch Witch JT4020 and JT100 All Terrain directional drills, the All Terrain Air Hammer expands the range of those drills to include penetrating the hardest rock. It features All Terrain technology, which enables the unit to continuously drill as it is being steered, resulting in a faster, more efficient bore. According to Ditch Witch, conventional air hammers require stopping the drill rotation to change directions, and mud motors typically begin to lose their effectiveness beyond 20,000-psi rock. The All Terrain Air Hammer is said to leave only dry cuttings and a small amount of foam that is used downhole to remove the cuttings. It has a low flow rate of 4 gpm, so fluid costs, cleanup time, and expense are minimal.
