4.5'' Remet Thread RC Hammer with Shank SRE547 for Mining Use 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. RC drill rigs with their considerably larger equipment can
typically reach depths of 300 to 600m. Depending on rig size and
ground conditions, there has allegedly been holes drilled to a max
depth of over 800m. The capacity to drill to such depths is
negatively impacted by groundwater meaning drillers require more
air pressure and also relies on the rig’s pullback capacity. Adavantages: 1.Achieves greater penetration in hard rock than air core drilling,
thanks to the percussive force and the strength of the drill bit. 2.Provides greater sample accuracy, and cuttings are easy to catalogue. The collected samples have an exact location and depth where they were acquired, making it easier to more precisely locate mineral deposits. 3.Ideal for harsh environments. RC drilling uses approximately 40% less water than diamond drilling, making it a better option for remote area drilling Specification:

About us: SOLLROC Reverse Circulation drilling (RC) ,from size 3’’ to 5.5’’, is a technique of drilling that uses dual wall drill rods that consist of an outer drill rod with an inner tube. By using compressed air to extract rock fragments sample,the samples travel through rods to a sample splitter at surface, avoiding all contact between the samples and the borehole wall that allows samples to be retrieved with minimal contamination,which is mainly used in deep hole exploration and mining grade control.
Delivery Way: By Air, By express or By Sea
