The use of rock drilling tools has become more and more common

The scope of use of rock drilling tools has become more and more common. In the process of using them, there are many contents that need to be mastered in advance, and its advantages must be known. Rock drilling tools are twist drills treated with nitriding. The key is that the CNC blades are placed in a combination of ammonia and water vapor. The manufacturer uses 540-560C heat insulation when manufacturing. After solving it, under this premise, of course, more than one chemical method can effectively improve the cutting performance. At present, most of the rock drilling tools on the market only guarantee that the color is black, but the specific use experience has not been effectively improved. Rock drilling tools are often produced in white, and natural cold-rolled twist drills can also be finished in white through fine grinding of the outer circle, which is often said to be high-quality, and we need to understand these when buying. In addition to the material itself, the quality control of the grinding environment is also very strict, and the surface of the CNC blade is not easy to be damaged.

There are various models and specifications of rock drilling tools, and people need to establish their own requirements when purchasing. Choose products suitable for your site. The non-grinding service life of rock drilling tools is about 5-6 times the service life of the drill bit with the same aperture. Project rate. Therefore, smooth connection and flange connection rock drilling tools with different apertures are used in various hard and brittle rock formations to cooperate with down-the-hole drilling rigs for rock drilling. In addition, the combination of rock drilling tools and hydraulic down-the-hole drilling rigs is a supporting facility for modern rock drilling technology. However, in the past 20 years, the development trend of button bit series products in various countries has been rapid. With the rapid drilling of hydraulic rock drills and the saving of auxiliary man-hours for rock drilling, the overall goal of increasing the drilling speed of industrial production has been achieved. In contrast, it has the characteristics of long sharpening time and faster drilling speed.
