 RE545 RC hammer button bits

Product description:

ROSCHEN carry a large inventory of RC bits for convenient and quick delivery. Standard bits come with higher grade carbides for longer, harder drilling performance.  Reverse Circulation drilling is one of the most frequently used methods of drilling used across the world as it is more cost effective and efficient than other methods of drilling. When compared to Rotary Air Blast and diamond drilling, RC drilling seems to be somewhere in the middle when it comes to cost, time, quality of samples, technique and depth.

Basics of Reverse Circulation Drilling:

1.  RC drilling uses rods with inner and outer tubes, the drill cuttings are returned to surface inside the rods. The drilling mechanism is a pneumatic reciprocating piston known as a hammer driving a tungsten-steel drill bit.

2.  RC drilling utilizes much larger rigs and machinery and depths of up to 500 meters are routinely achieved. RC drilling ideally produces dry rock chips, as large air compressors dry the rock out ahead of the advancing drill bit.

3.  RC drilling is slower and costlier but achieves better penetration than RAB or air core drilling; it is cheaper than diamond coring and is thus preferred for most mineral exploration work.
