"Rebore-Zit" Bit for Enlarging Wire-Filled Holes

Rebore-Zit.jpg

The "Rebore-Zit" is a very specialized piece of equipment, designed for enlarging holes through which wires are drawn without losing the wire itself. (No big deal on a stud as shown, but a royal pain if it happens inside a wall. You pull the wire through the wall, attach it to an eyelet on the end of the bit that doesn't rotate, then jam the whole thing back into the wall until you've gotten the size you wanted. Good for precision work, but if it were just drywall, I'd probably just pull the wire through and rough out a sloppy hole.

I'm sure there are almost none of you guys out there that actually need this bit, but I find these kind of specialized tools fascinating.

  1. What a terrific tool. If you’ve ever had the unenviable task of adding a wire to an existing wire-run, this tool on a long flexible bit extension would be terrific!

    (consider you have one coax going through the wall to your TV. You want to add another MVPD (add Satellite?) or add a two-tuner device. You have existing holes, existing wire, want to add another wire through those holes but the holes aren’t big enough for another wire).

    Alas, this seems to be a short bit (not 36″ anyhow) and I’ve already solved my problem in another way.

  2. Now if only someone could develop a little robotic version of this that traveled along the existing wire, widening holes and pulling a twine behind it for adding additional cables. More often than not, one has to pass through more than one stud, all buried behind drywall and well out of reach of any bit.

    All us low-voltage folks need tools like that. I recommend checking out some of the stuff made by Labour Saving Devices, like their Roy Rods and Magne-Pulls.
