In the drilling process, the drill bit is the main tool for breaking rocks, and the wellbore is formed by the drill bit breaking rocks. The quality of a wellbore formation and the time it takes to form depend not only on the characteristics of the rock formation being drilled and the performance of the drill bit itself, but also on the degree of compatibility between the drill bit and the formation.

Tungsten carbide drill bits are a type of cemented carbide drill bit, mainly made of sintered tungsten carbide and cobalt. They possess extremely high hardness and wear resistance, and are widely used for machining high-hardness materials such as stainless steel and cast iron.

Split anchor bolts are a new type of anchoring component used in geotechnical engineering support, primarily for reinforcing surrounding rock in tunnels, slopes, and foundation pits. Their core feature is the radial expansion of the anchoring section within the borehole using mechanical or hydraulic methods, forming a "split" anchoring structure. This results in stronger interlocking and frictional forces with the surrounding rock, enhancing the support effect.

Grouting guide pipe (also known as steel perforated pipe) is a small-diameter steel pipe used in tunnels and underground engineering for advanced pre-support and ground reinforcement. Grouting is injected into the pipe to improve the physical and mechanical properties of the surrounding rock and enhance stability.
