For flaring the end of a piece of electrical conduit, which tool should be used?

1. A power drill with a spade bit

2. A brace with a ream

3. A power drill with a countersink bit

4. A brace with an auger bit

The correct answer is: A brace with a ream

When flaring the end of a piece of electrical conduit, the appropriate tool is a brace with a ream. This tool combination is specifically designed for shaping and enlarging the ends of pipes or conduits to create a smooth, flared edge. The reamer is effective at gradually removing material, allowing for precision and control, which is essential for achieving the desired flare without damaging the integrity of the conduit. This is particularly important in electrical applications, where ensuring a tight and secure fit without sharp edges can prevent injury and ensure safe connections. The other tools mentioned are not suitable for this type of task. A power drill with a spade bit is typically used for drilling larger holes in wood, not for flaring. A power drill with a countersink bit creates a beveled edge for screws but does not provide the smooth, rounded flare needed for conduit. Finally, a brace with an auger bit is suitable for boring deep holes in wood or other materials but does not serve the flaring purpose effectively. Thus, the brace with a reamer stands out as the proper tool for this task.
