You’re trying to pull some wire through a hole with wire from a previous installation, but the hole just isn’t large enough. How the heck do you enlarge the hole without pushing the wire back through and losing it in the wall? The Rebore-Zit comes to the rescue. From the makers of the previously posted Base-Boar-Zit and other various -Zit products, the Rebore-Zit’s free-spinning swivel-eyelet allows you to keep the wire attached to the drill bit while you ream out the hole.
The procedure couldn’t be simpler: choose the proper Rebore-Zit bit, thread the wire through the swivel loop, and twist the wire so it’s securely attached to the bit — then push the bit into the hole, and enlarge it. When you’re finished, pull out the bit, and the wire is still attached. Repeat if you need to make a larger hole.
The Rebore-Zit comes in three different sizes: a 3/8″ bit to enlarge a 1/4″ hole, a 1/2″ bit to enlarge a 3/8″ hole, and a 3/4″ bit which also enlarges a 3/8″ hole. These bits run around $35 , $53, and $82 respectively — expensive, but how else are you going to enlarge a hole without losing the wire?
