5 Step Natural Diamond HQ Core Drill Bits For Hard Rock Formation With Fast Speed
Natural diamond surface-set bits
“SINOCOREDRILL” brand has a high reputation in and out of China.
Natural diamond surface - set bits differ from impregnated bits in that they only have a single layer of diamonds set onto the working surface of bits according to a pre-determined pattern, Its waterways are usually shallower than an impregnated bit because of the single layer of diamonds. Some bits are designed with face Discharge holes to minimize core wash when drilling sin soft and fractured formations.
We supply a wide range of surface set bits, which includes a variety of profiles, diamond grades and sizes
designed to provide the most efficient cutting ability in all different rock formations.
Some other types of bits such as pilot type, special discharge type or concave type non-coring special purpose bits are available on request.
Rule of thumb: The harder the rock it, the smaller the diamonds we should use.
Number of Stones is a very important factor in determining how well a big will cut. Our engineers use
mathematical formulae to set each diamond on bit cutting area to ensure proper overlap with a minimum of
diamonds to keep the carat weight (and initial bit cost) as low as possible in a balanced design.
Diamond Grade is the most important factor to take into consideration when selection a bit. As it affects total meters drilled and therefore affects cost per meter drilled. It obviously also affects bit price. The diamonds we use have been selected carefully and also have been improved over the years.
