Surface-Set Diamond Bits can be used with any tupe of core barrels.
By varying the diamond grade, size, quality, and matrix hardness
and crown shapes, the users can satisfactorily dril and core hard
and homogeneous formations.
Surface - Set Non-coring Bits are drilling for broken formation
rock which can't be cored. Crown are used to set with synthetic,
natural or polycrystalline diamond. It's used for drilling in soft
to medium hard formation rocks.

To select the right bit for the job, assess the speed and power of
your drill for the size and depths of the holes to be drilled and
assess ground conditions such as rock type/formation and down-hole
conditions.
