What type of drill bit is equipped with a hole in the end for the purpose of attaching a wire?

The bell hanger bit is specifically designed for drilling holes through walls and ceilings to allow for the installation of electrical wires, cables, and similar materials. The distinguishing feature of a bell hanger bit is the hole at the end, which enables the user to attach and pull wires through the drilled hole efficiently. This design allows for enhanced maneuverability in tight spaces typically found in residential and commercial construction.

In contrast, other types of drill bits serve different functions. The masonry bit is designed to drill into hard materials like brick and concrete but does not have the feature for wire attachment. The twist bit, commonly used for metal and wood, also lacks the hole needed for pulling wires. The auger bit is primarily utilized for drilling larger holes in wood, often for applications like boring deep holes, without the capability of wire attachment.
