REVERSE CIRCULATION DRILLING HAMMERS
 

Reverse Circulation RC drilling hammers and hammer drill bits provide outstanding performance along with outstanding reliability and simplicity. Our reverse circulation hammers are suitable for any exploration and grade control process to obtain an accurate sample with no contamination. RC drilling hammers can in most instances carry out continuous sample collection in a fraction of the time necessary with conventional or wireline coring.
 

Reverse circulation drilling is similar to air core drilling. The cuttings are returned to the surface through an inner tube and collected for later use. This type of drilling is done by either rotary drilling or percussion drilling with the aid of a down hole hammer. Reverse circulation drilling is a highly utilized drilling method for mineral exploration. RC is used to retrieve continuous samples from the ground where a solid core is not needed.
 

In RC drilling, air, or sometimes water, is pumped into a side inlet air swivel. The air is then blown down the outside of the pipe. Once the air hits the drill bit, it flushes and cools the air but also creates a vacuum that forces the air and cuttings up the center of the drill string and into the inner tube. The air then goes back up the drill pipe through the top drive and into a cyclone sampler. Western Drilling Tools manufactures all of its own RC equipment. The RC equipment is compatible with most others on the market.
 

A major advantage of reverse circulation drilling is continuous uncontaminated samples.
 

Roschen also manufactures a complete line of rc tools and accessories. Feel free to contact Roschen for more information on RC drilling, custom rc drilling tools and custom drilling tools.
