1.Button bit is well known for its high wear resistance on
medium-hard to hard abrasive rock formations (between 200 Mpa to
260 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
DTH hammers and bits are widely used in underground mining,
quarries, hydraulic and Hydro-Power Engineering, water well
drilling, Mineral exploration, anchoring hole drilling, geothermal
engineering, Subway excavation, another civil engineering. it has
the advantage of high flatness, smooth hole wall, high rigid of
drill rod and hammer, independent of high axial thrust, no limit of
drilling depth, low cost of devices and easiness to maintain.
