The diamond drill manufacturer introduces the choice of the degree of diamond drill
The drilling time of the drill bit, that is, the footage efficiency, is an important indicator to reflect the drilling level of the captain. The degree of the YK Drilling Tools diamond drill bit, that is, whether the hardness of the matrix and the rock formation are compatible, is the key to determining the footage efficiency. Therefore, the captain should Choose a gold drill bit with the appropriate carcass hardness.

At present, the main matrix hardness of the gold diamond diamond bit is divided into 3 categories: 15-18/20-25 degree diamond bit, 6-8 degree diamond bit and 25-28 degree diamond bit (grinding 50), according to different rock hardness and Choose a different category for complex situations. Their practical application is summarized as follows:

1, 15-18/20-25 degree diamond drill bit
This type of drill bit is mainly used in the drilling of conventional rock formations, such as limestone, shale and coarse-grained sandstone with low hardness. Degrees are the choice for drilling and opening in softer rock formations.
2, 6-8 degree diamond bit
This kind of drill bit has a particularly large sales volume in the market, and its production process can only be produced by a few manufacturers in Nanchang. It is characterized by drilling extremely hard granite, siliceous rock and volcanic rock, etc. In the case of low efficiency of conventional drill bit or slippage, the degree of 6-8 degrees is the only choice for the captain.
3. 25-28 degree diamond drill bit (grinding 50)
With the continuous innovation of drill bit production technology, the low efficiency of the composite drill bit in drilling broken rock layers, reinforced concrete and pebble layers has been solved. That is to choose a gold diamond diamond bit with a matrix hardness of 25-28 degrees. It is a reinforced type of 20-25 degree drill bit. It is characterized by outstanding wear resistance and can be compared to the shoulder composite drill bit. Therefore, the manufacturer also calls it “Yan 50″ drill bit, which means that its wear resistance has reached the standard of 50 degrees. , The footage is completely incomparable with the composite film. Therefore, the degree of 25-28 degrees has a large range of applications in the future and will dominate the market.

Technological innovation has also reduced the production cost of drill bits. Therefore, the price of diamond drill bits has been declining in recent years, and even extremely low-priced drill bits have appeared. However, it should be pointed out that the market needs products with high drilling efficiency and high cost performance. No manufacturer can gain a firm foothold in the market by relying on price alone. Only by producing diamond drill bits of different degrees suitable for different formations can we win the favor of consumers.
