136mm PR54 RC Button Bit with Carbide Buttons for Mining Exploration Drilling

Product Introduce:

RC, or reverse circulation, drilling is a tried and true drilling method in certain circumstances. Drillers usually use it on large-diameter holes because it is faster and easier to clean the hole. The fluid and cuttings flow up the drill pipe and down the annulus. In softer formations, this causes less washout and makes sampling faster and more accurate because cuttings are not contaminated by sloughing formation off the hole walls. They also come up the drill pipe very fast, giving an accurate formation log.

Adavantages:

1. Achieves greater penetration in hard rock than air core drilling,
2. Ideal for harsh environments.
3. Reduced risk of cross-contamination.
4. Faster and more efficient, reducing costs and providing greater returns.

5. Reduced man-hours at the drill with decreased exposure to potential accidents.
6. Requires less water than diamond drilling.

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.

Delivery Way:

By Air, By express or By Sea
