Product Description

Product Introduction:
Reverse circulation drilling (RC) is a drilling technique that allows samples to be retrieved with minimal contamination. The samples travel through rods to a sample splitter at surface, avoiding all contact between the samples and the borehole wall. 
Our hammer and bits are made of high quality Carbon steel with advanced heat treatment to assure the good drilling performance and long service life,all the products are manufactured as per the international standard. They are widely used by our customers all over the world.

Product Advantages:
1.Sturdiness
2.Fissure resistance
3.Optimum performance
4.Long life

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:
