Final answer:
The best tool for driving long deck screws is an impact driver, which is powerful, efficient, and designed for such tasks. It provides high torque and a hammering action, making it superior to standard drills, especially if it's a high voltage, brushless model.
Step-by-step explanation:
The best tool for a customer building a deck that requires driving a lot of long deck screws would be a cordless drill or impact driver. The best tool for driving long deck screws is an impact driver, which is powerful, efficient, and designed for such tasks. It provides high torque and a hammering action, making it superior to standard drills, especially if it's a high voltage, brushless model.
These tools are designed specifically for tasks like screwing and drilling. An impact driver, in particular, is ideal because it combines high torque with a hammering action that helps drive screws efficiently without stripping them. It's also more compact and lighter than a standard drill, which makes it easier to use for long periods. For professional or heavy-duty work, selecting an impact driver with a high voltage (18V or above) and brushless motor technology can provide additional power and longer battery life.
