hard rock formation 8.5 inch 215.9mm matrix body oil well drill pdc bit
"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.
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.
