Impregnated Diamond Bit
  • DESCRIPTION
  • Bit Sizes We Manufacture
The impregnated diamond bits are the most commonly useful bits in the mineral exploration, as they have the widest range of application. The carefully selected grades of high quality synthetic diamond are distributed in the depth of impregnated bit’s matrix series.The matrix layer of the crown contains a uniform distribution of these crystal that are embedded in a powdered metal bond. 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.

We can provide different shapes of bit waterways to achieve best performance.
  • Standard V ring type:
    • Can be used on most impregnated core bits
    • Great fluid circulation from the inside to the outside
    • Available with wider or larger waterways
  • Turbo type:
    • Greater ejection of fluids and cuttings
    • Reduced contact area with the same flushing performance
    • Recommended for higher rotation speeds
    • Available with wider or larger waterways
  • Face Discharged type:
    •Recommended for very soft and broken ground
    •The face discharge ports offer excellent flushing to prevent blockages in the waterway channels
    •Available with wider or larger waterways
  • Vortex type:
    •Recommended for very hard, abrasive and broken ground
Impregnation Depth
  • *The normal 10mm height diamond bits can meet most of the drilling jobs if the drill hole is not very deep. It is cost-effective.
  • *Diamond bits with high matrix will abviously increase the bit service life,and less change of diamond bits can save time for drillers. Such bit is much better for deep hole drilling.
  • DHM Bits This bit will work together with the down hole motor,which is for direction drilling.

Impregnated Bit Matrix Selection chart
When order,please select the bits according to your rock formation, how hard? Abrasive or not?

For some special or complicated ground,we will need to customize the diamond bits according to the actual drilling conditions.

Some suggestions for better use of our diamond bits:
SOFT ROCK FORMATIONS
• Low RPM’s
• Large diamonds/cutters
• Large waterways for better flushing and higher GPM flow rates
• Hard matrix for longer bit life

HARD ROCK FORMATIONS
• High RPM’s
• Small diamonds/cutters
• Small waterways
• Soft matrix to expose more cutting elements
