102mm Reverse Circulation RC Hardened Drill Bits for Mining Well Drilling
Product Introduce: Dual-wall reverse-circulation drilling uses flush-threaded double-wall drill pipe and high-pressure air to provide continuous return of formation and water samples. Cuttings and formation waters are not contaminated with drilling additives or mixed with other borehole material. The RC method employs dual wall drill rods that comprise an outer drill rod, with an inner tube located inside the drill rod. The inner tubes overlap, and seal on the tube below with O rings when the drill rods are screwed together. These inner tubes provide a continuous sealed pathway for the drill cuttings to be transported from the bit face to the surface.
Adavantages: 1. Achieves greater penetration in hard rock than air core
drilling, 2. Ideal for harsh environments. 3. Reduced risk of cross-contamination. 4. Faster and more efficient Technical Parameters RC bits Model SRC531

Working principle RC drilling works well in both overburden and soft, broken rock
formations but its main strength is when it gets to hard composite
rock. It is cost efficient due to the simplicity of the percussive
drilling process and because the equipment needed is less complex. Detailed Photo:
Delivery Way: By Air, By express or By Sea
