Cordless Drill

A cordless drill is mainly used for drilling holes in various materials. It provides a consistent rotational force, designed for drilling holes and driving screws. While an impact driver delivers higher torque for heavy-duty fastening.
On the other hand, a cordless impact drill (or impact driver) is designed for driving screws and bolts. It has an additional impact mechanism that delivers short, rapid bursts of power, making it easier to drive screws into tough materials. While a cordless drill can sometimes be used for light screw - driving tasks, an impact driver is more efficient for heavy - duty screw - driving jobs.

Yes, you can use a cordless drill machine as a screwdriver. Most cordless drills have a clutch setting that allows you to adjust the torque. By setting the clutch to a low - torque position, you can control the amount of force applied when driving screws, just like a regular screwdriver. However, for very delicate or small screws, a dedicated screwdriver might be more precise.

It depends on the airline's regulations. Generally, cordless drills are allowed in carry - on or checked baggage, but the battery must comply with safety standards. Lithium - ion batteries, which are commonly used in cordless drills, have restrictions on capacity and quantity. However, always check with your airline before flying with a battery drill machine.
