Power tools are essential equipment in the modern hardware industry, widely used for various tasks such as cutting, grinding, assembling, and more. They are typically categorized based on their application areas, including metal-cutting power tools, grinding tools, assembly tools, and railway-specific tools. Commonly used hardware power tools include electric drills, electric grinders, electric wrenches, electric screwdrivers, electric hammers, impact drills, concrete vibrators, and electric planers, each designed for specific purposes and industries.
1. **Electric Drill**: Electric drills come in various sizes, with main specifications including 4mm, 6mm, 8mm, 10mm, 13mm, 16mm, 19mm, 23mm, 32mm, 38mm, and 49mm. These numbers represent the maximum drilling diameter on steel with a tensile strength of 390N/mm². For non-ferrous metals, plastics, and other materials, the maximum drilling diameter can be up to 30-50% larger than the specified size.
2. **Electric Grinder**: This tool is used for grinding surfaces using a grinding wheel or disc. It comes in different types, such as straight grinders and angle grinders, each suitable for specific applications like metal shaping or surface preparation.
3. **Electric Wrench and Screwdriver**: These tools are used for tightening or loosening threaded joints. The electric wrench features a planetary gear system combined with an impact mechanism, while the electric screwdriver uses either a jaw clutch or gear transmission. Specifications vary, with common sizes ranging from M1 to M30 depending on the model.
4. **Electric Hammer and Impact Drill**: Designed for drilling and chiseling in hard materials like concrete and brick, these tools are ideal for rough work and installation tasks. When used with expansion bolts, they significantly enhance the speed and quality of pipeline and machine installations.
5. **Concrete Vibrator**: This device is used to compact freshly poured concrete, eliminating air bubbles and increasing structural strength. It operates using high-frequency vibrations generated by an eccentric block driven by a motor, which is powered by a 150Hz or 200Hz intermediate frequency supply.
6. **Electric Planer**: Used for smoothing wood or wooden components, it can also function as a small planer on a gantry. The cutter shaft is driven by a motor through a belt, making it efficient for woodworking projects.
