Surface Set Core Drill Bits , Diamond Cutting Drill Bits With Hard Matrix

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.

  • Surface set diamond bit is produced from a single layer of natural diamond setting on the surface of bit crown with hard matrix.

  • Surface set diamond bit is mainly recommended for drilling soft to hard formations. Generally speaking, surface set diamond bit can provide satisfying penetration rate.

  • To choose a right surface set for the formations drilled, we need at least consider the following aspects: diamond size, diamond grade, profile design.



Notice :

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.

Size:
ROSCHEN bits are available in all standard drilling sizes . Also, non-standard sized bits can be produced according to requirements from clients.

Crown Height:
ROSCHEN offers crown impreg depths of 9mm, 12mm, and 16mm .The taller crown heights provide improved bit stability and reduced vibrations, enhancing bit life and performance.


Waterways:
Various waterways are available for diamond impregnated bits. Differing waterways allow for better flushing in various ground conditions and drilling systems.


Matrix:
ROSCHEN impregnated bits matrices can be selected by our engineer according to ground conditions at client's work site.


Threads:
standard Q threads as well as thread types required by clients are available.

Principle of choosing diamond size--the harder the rocks, the smaller the diamond size should be.
  • Diamond Size

    Formation Drilled

    10/20 SPC*

    Soft formation

    20/30 SPC

    soft to medium formation

    30/40 SPC

    medium formation

    40/60 SPC

    Medium to hard formation

    < 60/80 SPC

    Very hard formation

    *SPC is short for Stone per Carat
    **40/60 is Forsun standard diamond size for natural diamond core bit
    ***Other sizes are available as per request




    Rule of selecting diamond grade--the harder the rocks, the better the diamond
    grade should be.

    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.
