Product Description

Product Description

Reverse circulation hammers and bits are used in exploration and grade control applications to obtain an accurate sample with no risk of contamination. Sollroc offers a range of reverse circulation hammers and drill bits that provide outstanding performance coupled with reliability and simplicity.

Reverse circulation drilling (RC) is a drilling technique that allows samples to be retrieved with minimal contamination. Drilling is typically done using a down-the-hole, tricone, or triblade bit. The samples travel through rods to a sample splitter at surface, avoiding all contact between the samples and the borehole wall. This quick execution technique is usually performed within a diameter of 150 mm and a depth that varies between 50 and 200 meters.

Our Advantages

1.Sturdiness

2.Samples extracted are reliable and free of contaminants;

3.The method is timely and cost-efficient

4.Long life

5.Reverse circulation drilling is simple and easy.

6.High penetration rates, and it has minimal environmental impact

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.

Our hammer and bits are made of high quality alloy steel with advanced heat treatment to assure the good drilling performance and long service life. They are widely used by our customers all over the world.

All the products are manufactured as per the international standard.
