High Air Pressure Black 5'' SRC40 Reverse Circulation RC Bit For Exploration
Product Introduce:
RC is a drilling method widely used around the world. The method is unbeatable in areas where water is scarce or expensive, such as Australia and Western Africa (and, for the same reason, in northern Canada).
RC drilling today produces samples of high quality and reliability. Dual-pipe RC drilling utilizes double drill rods where air is passed down the hole through the outside annulus and into the hammer. Drill cuttings are cleared from the bit by the air and travel up through the centre tube of the drill rods remaining free from contamination.
Adavantages:
A big advantage of RC is its high rate of penetration. Penetration rates often exceed 80 m per shift depending on ground conditions. The speed of drilling can often mean big cost savings compared to slower drilling methods.
Reverse circulation drilling has several environmental advantages. First and foremost, RC mostly requires no water for rock drilling. This is a benefit in areas with limited or sensitive water supply.

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:
