Surface Set Diamond Core Bits
Surface Set Diamond Core Bits are the drilling bits which a single
layer of industrial natural diamonds is mounted on the matrix as
the working surface for the required purpose. Therefore, compared
to the Impregnated Diamond Core Bits, the matrix is extremely hard
for holding the diamonds in postion throughtout the bit life.
Manufactuered Surface Set Diamond Core Bits provide the highest
quality They are highly recommended for the soft to medium hard,
abrasive, uncosoildated formations, and for those projects which
the timing is on the top of the priority list. Some special
designed Suface Set bits are also recommended for hard formations
with a lower rotational speed and bit load.
The Surface Set product line includes various diamond grades, stone
sizes and matrix profiles for different solutions.

FAQ:
1.Q: Can Surface Set Diamond Core Bits be used for drilling in deep
boreholes?
A: Yes, Surface Set Diamond Core Bits can be used for drilling deep
boreholes, but consideration should be given to factors such as
drilling equipment and bit stability.
2.Q: Can Surface Set Diamond Core Bits be used for drilling in
mineralized zones?
A: Yes, Surface Set Diamond Core Bits are commonly used for
drilling in mineralized zones to obtain representative core samples
for mineral exploration and evaluation.
3.Q: Can Surface Set Diamond Core Bits be used for drilling in
underground coal mines?
A: Surface Set Diamond Core Bits are not typically used for
drilling in underground coal mines, as other specialized bits are
more commonly employed for coal mining operations.
4.Q: Can Surface Set Diamond Core Bits be used for drilling in
highly fractured granite formations?
A: Surface Set Diamond Core Bits can be used in highly fractured
granite formations, but care must be taken to prevent excessive
core loss and maintain bit stability.
5.Q: Can Surface Set Diamond Core Bits be used for drilling in
narrow boreholes?
A: Yes, Surface Set Diamond Core Bits can be used for drilling in
narrow boreholes, provided the bit size is compatible with the
desired borehole diameter
