Customizable high-quality diamond composite drill bits for coal mines Alias: (PDC) drill bit Diamond Composite (PDC) Drill Bit Series Diamond composite (PDC) is a special superhard material synthesized from synthetic diamond and cemented carbide under high temperature conditions. It not only has the advantages of high diamond hardness, but also has strong impact resistance and large cutting edge. And other characteristics, using it as the blade of the drill bit can greatly improve the working efficiency of the drill bit, and it is an ideal drill bit for drilling into medium-hard and hard rock formations. Intensity distinction: The strength of the diamond composite drill is mainly determined by the strength of the diamond composite. At present, the strength of the diamond composite drill is mainly divided into three types: ordinary, reinforced, and high-strength; diamond composites are mainly divided into two types: 1304 and 1308 Species, 1304 and 1308 refer to the diameter and thickness of the composite sheet. The basic distinctions we use are: ordinary type, reinforced type and high-strength type; the ordinary type is 1304 flat composite sheet, and the reinforced type is 1304 spherical composite sheet and 1308 flat. Composite sheet, high-strength type is 1308 spherical composite sheet. The blades of high-strength diamond drill bits adopt newly developed spherical diamond blades, which are characterized by fast drilling speed and strong impact resistance. When the drill bit is drilled, the lip is used to scrape the rock in the normal and uniform formation. When the protruding part of the drill bit encounters a gap during the drilling process, the footage will be taken in an instant, which greatly reduces the accidental damage of the drill bit and improves the drilling level to deal with complex rock formations. . See the table below for suitable rock formation and drilling procedure parameters: Adaptation rock formation parameter table:

 

 

Row number	Type	Applicable rock formation
1	Ordinary PDC bit	Soft-medium hard rock with F<10
2	Strengthen the PDC bit	Medium hard rock with F=10-12
3	High-strength PDC	drill bit Hard rock with F<18

Application Field: At present, the application fields of diamond composite drill bits are relatively broad. Our company's diamond drill bits are used in coal fields, oil drilling, geological exploration, water conservancy and hydropower, railway highways, tunnel construction and other industries across the country. Product Advantage Speedmade's diamond composite drill bit, the support body is made of steel forged and formed, and processed by vacuum automatic heat treatment equipment to increase mechanical properties. The ordinary type uses domestic composite blades as the blades, and the high-strength type uses the blades of the American GE company. The corresponding quality level is selected according to the different geological conditions, which can achieve higher products and achieve energy-saving economic indicators. ... Speedmade's drill bits are used in coalfields, oil drilling, geological prospecting, water conservancy and hydropower, railway and highway construction, tunnel construction and other industries across the country. The two-wing PDC bolt bit (half-slice standard type) is suitable for rock formations below grade 8, and the drilling life is 10-30 times that of ordinary alloy bits under the same rock formation conditions. The efficiency is improved, without grinding, greatly reducing the labor intensity of workers and saving Working hours. The key raw materials of the two-wing PDC bolt bit (half-piece reinforced) blade blade are supplied by the American GE company. Its diamond content is 1.5 times that of the ordinary bit. The performance and efficiency are significantly improved, the overall cost is reduced, and it is suitable for medium-hard rock formations below grade 12.
