Diamond drill bit wall hole drilling machine rock drill bit Shandong Anhui
 There are many types of diamond drill bits: diamond composite drill bit, diamond PDC drill bit, diamond anchor drill bit 
PDC composite drill bit, three-wing diamond drill bit, two-wing diamond composite drill bit
 
A drill with a cutting edge is called a diamond drill.The drill bit is an integrated drill bit, the whole drill bit has no moving parts, the structure is relatively simple, and it has high strength, high wear resistance and impact resistance. It is one of the three new drilling technologies in the world in the 1980s..Field use has proved that when drilling in soft-medium-hard formations, the diamond bit has the advantages of high speed, large footage, long life, stable operation, fewer downhole accidents, and good well quality..The diamond drill bit is not only used for a long time, but also can be reused. The use effect of the returned diamond drill bit is similar to that of the factory diamond bit, which can save a lot of drilling costs..
 
Advantage: taper drill bits 
 
1 The force balance design enables the drill bit to have good steering, which is suitable for the application of downhole motors in directional drilling, and has a small radial vibration;
 
2 The reasonable arrangement of the patented PDC composite sheets of different structures at different positions of the drill bit makes the drill bit more aggressive and resistant to abrasion;
 
3 Strong aggressive design enables the drill bit to obtain a high ROP;
 
4 The dynamic flow field simulation technology is applied to hydraulic design to optimize the flow field at the bottom of the well, which is beneficial to increase the chip removal speed and prevent mud pack.
 
Because the material of the PDC bit is mainly cast tungsten carbide and diamond composite sheet, it has a long life and high value.
 
The diamond composite PDC anchor bit has good stability, long service life, high drilling efficiency, low-pressure and medium-speed drilling, good gauge effect, wide range of use and superior cost performance. It has the characteristics of drilling life in the same rock formation. It is 10-30 times that of ordinary alloy drills, and the efficiency is at least increased by more than 50%, without grinding, effectively reducing labor intensity and saving man-hours.It is used for the drilling of anchor net support holes in mining, hydropower, transportation and other departments.Ithe companyAccording to customer needs and geology drill shank adapter Conditions for custom-made various diamond composite drill bits.
 
Applicable rock formation: 6f12
 
Specifications: 25, 27, 28, 29, 30, 32, 36, 42
 
Diamond composite half piece/disc anchor bit:
 
Purpose: Mainly used for the drilling of bolt-net support holes in coal mines, providing a strong guarantee for fast and efficient roadway excavation.
 
Features:
 
Significantly improve the drilling speed and drilling efficiency of the medium-hard rock layer (sandstone)
 
The blade has good wear resistance, strong resistance, no need to repeat grinding, long drill life.
 
 Diameter reduction is not easy, and the rate of porosity is high, which greatly reduces the waste of medicine coils and anchor rods, improves the construction efficiency, reduces the labor intensity of the workers, and has a wide range of lithology.
 
The drill bit adopts a new type of superhard material diamond composite sheet, and the bit has a long life
 
Adapt to rock formations: complete and broken formations from soft to medium hard
