Multiple Drill Modes: A drill driver set（https://www.dastool.cc/product/power-tool/electric-drill/） typically offers multiple drill modes, including drilling, driving, and hammer drilling. The drilling mode is used for standard drilling tasks, while the driving mode is designed specifically for screwdriving applications. The hammer drilling mode is particularly useful for drilling into harder materials like concrete and masonry. Having these different modes in one tool eliminates the need for multiple tools, saving time and effort. Interchangeable Bits: A drill driver set comes with a wide range of interchangeable bits, allowing users to tackle various tasks without the need for additional tools. Common types of bits include Phillips, flathead, hex, and square bits, among others. The ability to quickly and easily switch between different bits enhances efficiency and productivity, as users can adapt to different drilling and driving needs.
