How to Use a Bell Hanger Bit

Find the Hole in the Tip

• Examine your bell hanger bit, and you will see a hole near the tip. This hole will not affect the drill's power to create holes in various materials. Drill the hole you need to make for running wire, and ignore the hole during this phase of your wiring job. Make sure the width of your bell hanger bit is wider than the wire or cable you plan to run through the hole.

Push the Bit Out to Expose the Hole in the Tip

• Once your bell hanger bit breaks through to the other side of the material you are drilling, stop the drill. Push the bit far enough out of the drilled hole to allow your coworker to see the small hole that is in the tip of the bit. Unplug the drill so it cannot accidentally turn while the coworker handles the bell hanger bit.

Hook a Wire Through the Drill Bit

• Have your coworker hook a wire through the hole in the bell hanger bit. This should not be the electrical wire, but something like a coat hanger or non-electrical wire. The coworker should hook the electrical wire to the end of the non-electrical wire. This should be done by stripping the insulation off the end of the electrical wire and twisting the exposed copper wiring around the non-electrical wire. The coworker should test this connection to make sure it will not pull loose.

Pull the Wire

• Pull the drill bit back through the hole you drilled. Do this with a steady motion, and if the bit catches at any point, do not jerk it. You want to avoid pulling the wire out of the hole in the drill bit. Pull the bit all the way out, and when the non-electrical wire comes out of the hole, pull it until you see the electrical wire that is attached to it. This method allows you to pull wire long distances without poking and prodding.
