Manufacture Supplier / HQ Impregnated Diamond Bits / Diamond Core
Drill Bits / Core Drill Bits / Rock Drilling Tools
Impregnated diamond drill bits are designed to perform as grinders,
diamond are embedded in an infiltrated or sintered matrix.
The matrix erodes away at the same rate as the diamonds become worn
and rounded, thus new sharp diamonds are exposed to continue
cutting through the rock.
Imprgnation Depth
This refers to the thickness of the diamond impreganated matrix
layer on a core bit crown as shown in the illustration below.
Rockcode offers many sizes of core bits with standard impregnation
depths from 5mm to 20mm. Other customer defined impreganation
depths are available on request. Unless otherwise spcified, a
standard 12mm impregnation depth is supplied for most of our
Customer.
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.

Feature:
1. Significantly outperforms the successful Series range in
drilling speed and bit life.
2. Protects the diamond from oxidation and surface degradation.
3. Inhibits the premature "pull-out" of the diamond.
4. Available in multiple standard configurations and selected on
the basis of relative rock hardness and ground conditions.
