What is the working principle of diamond core bits? The drill bit that makes the cutting edge is called a diamond core bit. The drill bit is an integrated drill bit. The entire drill bit has no moving parts. The structure is relatively simple, with high strength, high wear resistance and impact resi
What kinds of drill pipe can be divided into? The drill pipe is a steel pipe with thread on the tail, which is used to connect the surface equipment of the drilling rig and the drilling and grinding equipment or bottom hole device located at the bottom end of the drilling well. The purpose of t
How to classify core barrels? A section of pipe connected to the upper part of the drill bit to accommodate and protect the core during core barrel.

Product Description
RC hammer button bits RE543
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.
ROSCHEN RC bits sizes.
1. RC bits 86mm -102mm for 3" RC hammer RE531
2. RC bits 114mm -127mm for 4" RC hammer RE004
3. RC bits 121mm -133mm for 4.5" RC hammer RE542/RE543
4. RC bits 124mm - 138mm for 5" RC hammer RE545/PR40
5. RC bits 133mm - 146mm para 5.5" RC hammer PR52/RE547/PR54/MX5456
ROSCHEN adjust button number, button configuration, button diameter to get ultra-performance and reduce the drilling cost for you according to your rock formation situation.

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.
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;
