5.5 Inch Rock Drill Polycrystalline Diamond Compact Bits For Geothermal Well Drilling

PDC Drill Bit

Product Description

"Matrix" is a very hard, rather brittle composite material comprising tungsten carbide grains metallurgically bonded with a softer, tougher, metallic binder. Matrix is desirable as a bit material, because its hardness is resistant to abrasion and erosion. lt is capable of withstanding relatively high compressive loads, but, compared with steel, has low resistance to impact loading.

Matrix is relatively heterogeneous, because it is a composite material. Because the size and placement of the particles of tungsten carbide it contains vary (by both design and circumstances, its physical properties are slightly less predictable than steel. Matrix-body PDC bits are commonly preferred over steel-body bits for environments in which body erosion is likely to cause a bit to fail. For diamond-impregnated bits, only matrix-body construction can be used.

Technical Parameter

1.PDC drill bit is used for weak and dangerous rock, foundation treatment, broken ground and other grouting reinforcement drilling;
2. It is used for tunnel ventilation, exhaust gas, monitoring drilling of rock mass buildings and concrete sampling drilling.
3. The application of balancing software makes the angle of cutting teeth more scientific.

1. MEDIUM TO HARD FORMATION DRILLING
Medium to short parabolic profile with medium to heavy cutters desity helps to obtain better ROP in medium to hard formations with lower compressive strength and small abrasive layers.


2. DURASET GAUGE
Super strong material promotes gauge wear resistance to provide long bit life

3. HYDRAULICS
Cuttings removal and bit cooling for bits are optimized by matching the volume of rock removed by the cutter on each blade with the proportional fluid flow.

4.UNIQUE BACKRACK DESIGN
The cutter's back rake has been unique design, reducing the bit torque and increasing aggressiveness.
