4inch RE004 RC Button Bits

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.

Product Description

RC hammer button bits 4inch RE004


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.  Diamond buttons are available by special order on all bits. Economize the diamond button cost even more by reclaiming the used diamonds (if in good shape) and have them reinserted in to a new bit body.   Please contact us for additional details.

 

Reverse Circulation (RC) drilling is used to collect mineral and rock samples quickly and efficiently using a large rotary drill and air compressor. Reverse Circulation (or RC) 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 RAB (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.

Our RC bit design that drastically improves hole cleaning and overall drilling speed. By deepening the channel ways and side exhausting, the new design is able to efficiently flush more air over the bit face resulting in a greater recovery and accurate down hole sample at the surface, all are at a much faster drilling rate.


Drilling Supply Store range of high quality Reverse Circulation RC drill bits were specifically designed to work with our RC Hammers. Because of our drill bit sealing mechanism, sample contamination problems are not an issue. Using our RC Bits provide outstanding performance and reliability.


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.

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.
