HQ3 Triple tube Surface set core bit More diamond and Higher
penetration rates for soft formations
SURFACE SET CORING BITS
Surface set coring bits are typically used for higher penetration
rates than impregnated bits in softer formations. They utilize a
single layer of natural diamonds set in a hard matrix.
The choice of a Surface Set Bit will be dictated by the rock type.
The diamond size, crown design and matrix hardness used will be
determined by the hardness of the formation. The friability of the
core will determine the type of fluid passages. The surface set bit
provides a greater esure of diamonds than the impregnated bit and
therefore faster penetration in soft formations.
Face Profiles of surface set core bit:
Semi-round: it is mostly used in the core bit with bit kerf thickness less
than 11mm. It can drill various formations. The core bit with
semi-round profile has long bit life, and can avoid damage; while
the bit kerf thickness is over 11mm with semi-round profile can be
applied in drilling abrasive formations.
Stepped profile: core bit kerf thickness over 11mm usually has this kind of
profile. Bit with Stepped profile can obtain high penetration rate
with good stability in drilling. However, it is not recommended in
fractured very abrasive formations. When the core bit of bit kerf
less than 11mm has stepped profile can facilitate drilling speed
and have better drilling stability.
The matrix of our impregnated bits is designed to expose new
diamonds to the bits' cutting face as wear occurs. Fast penetration
rate is maintained as a result of this action.Our impregnated bits
are manufactured to give optimum penetration rates and bit life,
which is required to keep the cost of diamond drilling to a
minimum.The optimum diamond size, concentration and matrix type are
dependent on the hardness and abrasiveness of the formation to be
drilled.
