2. Rock drill: used to drill holes with a diameter of 20 ~ 100 mm and a depth of less than 20 meters in rocks above medium and hard. According to its different power can be divided into pneumatic, internal combustion, hydraulic and electric rock drill, of which pneumatic rock drill is the most widely used.

Drilling is a fundamental process in various industries, from oil and gas extraction to mineral exploration, construction, and even scientific research. The success of any drilling operation largely depends on the materials used during the drilling process. This article will delve into the different types of drilling materials, their properties, and their significance in enhancing drilling efficiency and safety.

Portability and Ease of Use

In the world of drilling and excavation, the efficiency of your equipment largely depends on the quality of the tools used. One such crucial component is the cutting tool itself, and in terms of augers, bullet teeth play an essential role. This article aims to explore the significance of bullet teeth for augers, their design, applications, and advantages.

It is important to know that the shape of the sand has an important impact on the surface finish of the casting. Circular sand is better than triangular sand because the triangular sand has a large gap, which is easy to lead to defects such as porosity; According to the nature of the casting, the sodium silicate quartz sand is selected to form a spalling layer, and combined with the characteristics of cooling and shrinkage of the casting, the surface defects are reduced. Coating a protective layer on the surface of large castings, such as the film on a coated sand mold, can improve the surface finish of the sand mold and reduce the surface defects of the casting.  

4. Market Trends and Demand

In recent years, the demand for efficient drilling solutions has soared, especially in industries requiring rigorous digging and excavation. One of the most critical components of a drilling operation is the drill bit, and among the various types available, spiral drill bits stand out for their innovative tooth design. This article discusses the features, benefits, and applications of spiral drill bit teeth, providing insights into why they are increasingly favored in various drilling applications.

Market dynamics also influence the price of drilling machines. Economic factors, such as fluctuations in raw material costs, changes in labor costs, and overall market demand, can lead to price variations. When demand for construction and industrial projects rises, so too can the price of drilling machines due to increased competition for high-quality equipment. Additionally, advancements in technology can render older models obsolete, affecting their resale value.
