Functionality is paramount in the design of a coupling sleevecoupling sleeve. It must be able to handle not only the torque being transmitted but also any axial or radial loads that may occur. Some designs include rubber or metal elements to absorb shock and reduce noise, further enhancing the performance of the coupling system. Additionally, the sleeve should allow for easy installation and removal to facilitate maintenance and replacement when necessary.

Another factor that could be contributing to the price increase is the raw material costs. The production of power tools requires a variety of materials, including metals and plastics. These materials can be expensive, and any increase in their prices will inevitably be passed on to consumers in the form of higher product prices. In recent months, there have been reports of shortages in some raw materials, which could be another reason for the price increase.

In addition to their mechanical advantages, tapered drill rods contribute to enhanced drilling accuracy. The gradual change in diameter helps maintain a consistent hole trajectory, particularly in directional drilling operations where precision is paramount. They also offer better control over the drilling depth, allowing operators to reach targeted depths more accurately They also offer better control over the drilling depth, allowing operators to reach targeted depths more accurately They also offer better control over the drilling depth, allowing operators to reach targeted depths more accurately They also offer better control over the drilling depth, allowing operators to reach targeted depths more accuratelytapered drill rod.

2.Conductive fiberglass grating
Fibergalss grating itself is an insulator, non conductive, non thermal conductivity, but in some specific places, it also has a conductive requirements. The detailed operation method is to eliminate the damage of static charge inoculation in the rock layer with a thickness of about 3~5mm. The conductive grating also has same characteristics  with traditional glass steel grille ,such as corrosion resistance, flame retardant,anti strike, skid resistance, light weight and practical in refinery and armaments manufacturing factory, high-tech industry, computer room, chemical plants, dry areas and underground mining operations.
