In machining, reaming hole machining is often encountered. Because the number of teeth of the reamer is more, the guidance performance is good, the diameter of the heart is large, the rigidity of the tool is good, the processing margin is less, the thickness of the chip is thinner, can obtain higher

PDC drill bit is very specific to the formation. In directional construction, as the strength of the formation increases, the tool face changes greatly. The PDC drill bit mechanical drilling speed is significantly higher than that of the roller cone bit, and it can be achieved with a smaller WOB. Th

PDC core drill bits selects high-quality diamond composite sheet, which has the characteristics of wear resistance, high drilling efficiency, and constant quality. For medium-hard and hard rock formations of f=1-16 level, PDC core drill bits can destroy them in one blow. If the rock mass is extremel

The working principle of the hole opener is relatively simple: in the ordinary hole opening mode, it is the same as the hand drill, the motor drives the gear drive, the gear drives the rod rotation, which in turn drives the drill rotation so that the hole opener can complete the drilling work, this

Due to the high wear and tear of oil drilling and geological exploration work, proper use and routine maintenance of single roller cone bits are essential. So how do you carry out suitable maintenance on single roller cone bits?Here is the content list:l How to use single roller cone bits.l Repair a

With the development of the times, the efficiency of underground operations has greatly improved. PDC core drill bits are one of the important factors to improve construction efficiency. PDC core drill bits are very suitable for drilling rock from underground wells for analysis. PDC core drill bits

Tricone drill tricone bit is much cheaper than natural diamond tricone bits after the PDC drill tricone bit was successfully manufactured and used in the early 1970s, it has been developed rapidly. When we choose and buy mine tricone tricone bit, there are a lot of matters that need to be paid atten

Reamers are typically made of carbide or high-speed steel (HSS), and these multi-edged rotary cutting tools can be used in the metalworking industry to expand and trim holes to higher precision and precision. To ensure the quality of the project, the product must be completed to a high standard. We'
