Product Description
Reverse circulation (RC) drilling uses a bit attached to a
down-hole hammer to produce a hole. Unlike diamond drilling, RC
drilling produces samples of rock cuttings rather than a sample of
rock core. The down-hole hammer is powered by compressed air, which
also acts as the medium bringing the drill cuttings up to surface.

Features
1. Using higher grade carbides for longer life;
2. Minimizes hole erosion in fragile formations
3. Drills faster through soft formations with less blockages
4. Drills straighter through consolidated and unconsolidated
formations
Product application
DTH drilling tools 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.
We provide high quality and durable DTH drilling tools for:
• Mineral Exploration Drilling
• Civil engineering and Mining
• Blast Hole Drilling
• Environmental Drilling
• Water well Drilling
• Geothermal Drilling
• Ground Engineering
• Gas / Oilfield /coal seam Drilling
• Geotechnical Drilling
• HDD Trenchless Drilling
