QL30 QL40 QL50 QL60 QL80 Shank DTH button bits for DTH drilling
QL30 QL40 QL50 QL60 QL80 Shank DTH button bits for DTH drilling
DTH drilling tool is 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. At the
drilling hole of dia.105mm-dia.500mm, a plenty of the DTH drilling
tools are used.
Features:
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.
