The impact driver is an essential tool for many, serving as a versatile addition to any toolbox. Equipped with the appropriate bit, it can also function as a drill, offering flexibility for various tasks. Ideal for projects requiring the insertion of numerous screws or driving long screws into tough materials, owning an impact driver is highly recommended. Unlike compact drills, impact drivers excel in handling large screws and bolts efficiently. What sets impact drivers apart is their ability to automatically apply additional rotational force when faced with resistance, providing two to three times more torque compared to traditional drills. This feature not only enhances efficiency but also reduces strain on the user's hand and wrist. For tasks involving substantial fasteners such as deck or pergola construction, an impact driver significantly simplifies the process. Unlike compact drills, impact drivers lack variable speeds or settings, operating on a straightforward all-or-nothing basis. This simplicity, combined with their superior torque capabilities, makes impact drivers indispensable for a wide range of projects.
