Shank PR40 138mm DTH RC Hammer Rock Bits for Geological Exploration
Product Introduce:
RC drilling uses rods with inner and outer tubes, the drill
cuttings are returned to surface inside the rods. The drilling
mechanism is a pneumatic reciprocating piston known as a hammer
driving a tungsten-steel drill bit.
RC drilling utilises much larger rigs and machinery and depths of
up to 500 metres are routinely achieved. RC drilling ideally
produces dry rock chips, as large air compressors dry the rock out
ahead of the advancing drill bit.
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.
Delivery Way:
By Air, By express or By Sea
