Down The Hole Hammer Introduction
1. superior alloy steel: Hardness and wear resistance combined alloy steel, supplied by national top level special steel manufacturer superior
2. Longer Service Life: All parts of the DTH hammer and bits are heat treated,longer life,less failure.
3. High Efficiency: More efficient energy transfer, faster drilling speed,15%-30% faster penetration than conventional DTH hammer.
4. Saving Oil: Lower air consumption and lower oil consumption.
5. Working pressure from 6 Bar to 35 Bar(0.6~ 3.5Mpa)
Down The Hole Hammer Features:
1. Button bit is well known for its high wear resistance on medium-hard to hard abrasive rock formations (between 2.0 Mpa to 2.6 Mpa compressive strength). Featuring spherical tungsten carbide inserts that is known to have strong configuration against carbide fracture.
2. Recommended for eliminating hole deviation.
3. Widely used drifting and tunneling.
4. Bit face design is ideal for medium-hard to hard abrasive rock.
