Product DescriptionWith bottom discharge diamond core bits, which
is suitable for triple tube core barrels, to improve the flushing
fluid's erosion against the core during drilling.The main crown
technical parameters of impregnated diamond core bits include
diamond grade,size,concentration and quality,matrix hardness and
crown shapes.The users can make rational selections according to
the formations to be drilled.To avoid excessive bit wear,tungsten
carbide inserts are used on both sides on the waterway,and gage
stones are a bit larger.Surface Set Diamond Core Bits can be used
with any type of core barrels. By varying the diamond grade, size,
quality, and matrix hardness and crown shapes, the users can
satisfactorily drill and core hard and homogeneous formations.The
choice of the diamond bit crown shape:W ProfileSuitable for
drilling hard dense formations with high penetration
rate.Semi-Round ProfileImpregnated bits with this profile are
recommended for use in highly fractured formations with good
drilling stability. Surface set bits of this style have a long bit
life and the matrix is not easy to be damaged.Flat ProfileIt's
suitable for various rocks, often used in impregnated casing bits,
casing shoes as well as the bits with very hard matrices(e.g. F1,
F2).Cross ProfileIt's especially designed for ultra-hard
formations, such as granite (hardness 8-9), ganister, quartzite,
siliceous limestone, chert, etc.Multi-Step ProfileMulti-Step type
impregnated bit are suitable for soft to medium hard formations and
alternating hard-soft formations. With very good drilling
stability, it makes the borehole not liable to deflection and the
penetration fast. This profile is also often adopted in thick-kerf
surface set core bits, with good drilling stability and fast
penetration.Shaped Gear ProfileIt's suitable for competent
formations, and can expand the flushing ways and improve the
penetration rate.Face DischargeIt's suitable for sedimentary and
metamorphic formations, or the formations including with lots of
mineral powders, this design can protect the core from flushing and
improve the getting effciency of core samples. Size
