Answer :
Final answer:
The best machine for running a screw gun is an Impact Driver, as it is specifically intended for screw driving tasks, providing high torque with minimal effort and combining rotation with concussive blows for efficiency. So, the correct answer is B.
Explanation:
When it comes to running a screw gun, the best choice among the options provided would be an Impact Driver. Impact drivers are specifically designed for driving screws and bolts with greater efficiency. They deliver high torque output with minimal effort from the user, making them more effective than Cordless Drills, Hammer Drills, or Rotary Tools for this task. Unlike cordless drills that apply constant rotational force, impact drivers combine rotation with concussive blows to drive screws in more efficiently. This makes them ideal for tasks that require driving large or long screws.
While Cordless Drills and Hammer Drills are versatile tools for a wide range of drilling and driving tasks, their design is not as optimized for screw driving as that of the impact driver. Hammer drills, for instance, are best suited for drilling into masonry and concrete, using a hammering action that cordless drills and rotary tools lack. On the other hand, Rotary Tools are better suited for precision tasks such as cutting, engraving, or sanding, rather than driving screws.
