RC button bits RE545

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.

Product Description

RC hammer button bits RE545


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.

RC BITS RE545

Applications:

RC drilling is a technique used in the majority of stages of mine development. As it is cheaper than diamond core drilling, it is often used in first stage exploration mining to delineate a potentially extractable ore body. It is also preferable to RAB or air-core drilling when trying to reach great depths, but RC drilling is slower and more expensive than either of these two methods. RC drilling is also consistently used during in-pit grade control and the development stage of an ore body.- Manufactured using premium hardened metals for long life;
- Maximum material recovery, up to 98%;
- No cross contamination of samples;
- Handles injection of water, foam, oil, and polymers without performance loss;
- Delivers maximum drilling under water.

Accurate sampling Reverse Circulation (RC) drilling is gaining recognition and is already the most common mineral exploration drilling method used in many regions of the world. Combined with the ROSCHEN RC 40/50 hammer it is unbeatable for obtaining accurate and uncontaminated rock samples at high speed and low cost. ROSCHEN produces the complete RC drill string including hammer, bit and pipes, for both in-pit grade control and exploration drillers.
