Product Details

Reverse Circulation Drill Bits and Shroud Drill Head RC Drill Bit from 3'' to 5.5''

Product Introduce:

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.

Adavantages:

1. Manufactured using premium hardened metals for long life;

2. Maximum material recovery, up to 98%;
3. No cross contamination of samples;

4. Handles injection of water, foam, oil, and polymers without performance loss;

5. Delivers maximum drilling under water.

About us:

SOLLROC Reverse Circulation drilling (RC) ,from size 3’’ to 5.5’’, is a technique of drilling that uses dual wall drill rods that consist of an outer drill rod with an inner tube. By using compressed air to extract rock fragments sample,the samples travel through rods to a sample splitter at surface, avoiding all contact between the samples and the borehole wall that allows samples to be retrieved with minimal contamination,which is mainly used in deep hole exploration and mining grade control.
