What type of bit is designed with a hole at the end for wire attachment?

• A. Drill bit
• B. Bell hanger
• C. Screwdriver bit
• D. Fish tape

Answer: (B)

The correct answer is the bell hanger, which is specifically designed for installing electrical wires in walls and ceilings. The characteristic hole at the end of a bell hanger bit allows for wire attachment, enabling electricians to pull wire through conduits or walls conveniently. This feature makes it very effective for tasks that require running cables over long distances, especially in tight or hard-to-reach spaces.

The other choices do not fulfill this function: drill bits are primarily used for creating holes in various materials but do not have a mechanism for wire attachment; screwdriver bits are designed for driving screws and similarly lack the specific design needed for attaching wire; fish tape, while used for routing wires through walls, does not involve a bit that attaches to wire in the sense needed for this question. Each tool serves distinct purposes in electrical work, but the bell hanger is uniquely suited for wire attachment through its design.
