5.5'' Carburized Treatment Process RC Bit For Well Drilling SRC052/SRC054/SRC547
Adavantages:
1.The longer life of the drill: the alloy material, with longer
using life which better than the similar products
2.High Drilling Efficiency: the drill buttons is wear-resistant, so
that the drill can always keep sharp, thus greatly improving the
speed of the drilling
3.The drilling speed is stable: the bit is scraped and cut to break
the rock.
4.Good Performance: the New Diamond bit has strong wear resistance,
good diameter protection and can make the cutting teeth be used
efficiently.

Product Introduce:
Much like air core drilling, RC drilling returns cutting to the surface through an inner tube inside the rod. This is achieved by blowing air down the rods at a rate up to 1500 Pascals. This creates a pressure differential that pushes cuttings and water up via air lift.
The drilling component is powered by a pneumatic reciprocating piston (also known as the hammer), which drives a steel drill bit.
The two most commonly used drilling bits in RC systems are the fixed cutter and roller cone, both of which are advantageous depending on the project and geographical location of the site.
RC drilling is primarily used on large machinery and drill rigs and often goes to depths of 500 meters.
High quality RC equipment also has the ability to dry out the rock with large air compressors before the drill hits, which provides dry rock chips and, in turn, better samples.
Basics of Reverse Circulation Drilling:
(1) 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.
(2) RC drilling utilizes much larger rigs and machinery and depths
of up to 500 meters are routinely achieved. RC drilling ideally
produces dry rock chips, as large air compressors dry the rock out
ahead of the advancing drill bit.
(3) RC drilling is slower and costlier but achieves better
penetration than RAB or air core drilling; it is cheaper than
diamond coring and is thus preferred for most mineral exploration
work.
(4) Reverse circulation is achieved by blowing air down the annulus
of the rod, the differential pressure creating air lift of the
water and cuttings up the inner tube which is inside each rod. It
reaches the deflector box at the top of the drill string then moves
through a sample hose which is attached to the top of the cyclone.
The drill cuttings travel around the inside of the cyclone until
they fall through an opening at the bottom and are collected in a
sample bag. For any drill hole there will be a large number of
sample bags, each one marked to record the location and drilling
depth that the sample was obtained.
The collected series of sample bag cuttings are later taken for
analysis to determine the mineral composition of the drill hole.
The analysis results of each individual bag represents the mineral
composition at a particular sample point in the drill hole.
Geologists can then survey the drilled ground analysis and make
decisions about the value of the overall mineral deposit.

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.
