Mysterious Drill Bit

I found this in a Lista cabinet that came home with me. Was under the drill organizer so didn't get cleaned out.
Trying to figure out what it would be used for. Fluteing doesn't go all the way to the end. Google search failed me.

Any thoughts?
Thanks all!
Matt

Looks like a spiral cutting bit. type you would use in a rotozip style tool for drywall and other types of materials. I have some bits that look like similar that I use in my dremel.

You brought a lista cabinet home and all we get is a picture of a lousy drill bit??? WTF??

Bought is not a word to be used for these.. they came home with me after we moved into a new building at work. :D

Here is a tease of 2 of the 3 I got.. waiting to get my garage clean from moving storage unit into it :/.
So far they are full of random stuff that is small enough to fit, can't wait to get stuff organized, once I do I will make a thread about it all (a grinder, vise, few other things came home too)

A E Numan, that was my initial thought, but wanted to see if it might actually be something real.

See, that is a "You ****" all day! I love me some Listas! Got a new one arriving sometime soon, my others were getting lonely.

It appears slip knot and 619diofan are right. Doing a rotozip drywall search shows that exact thing.
Thanks guys!

Strouty, I was estatic to bring them home. Have been in love with them (Lista) since first using them in the military. Told my wife I needed them because it's a bucket list item, and we can hand them down to the kids someday. :)

It's a drywall tracing bit for zipping out outlets and window/door openings. You measure the outlet and then hang the sheet of drywall with a couple screws and then mark the center of the outlet. Pop the bit threw the drywall and go to your right till the bit hits the side of the box. Pull out a little to get to the outside of the box and then go counter clockwise and the bit will "ride" the box and be a perfect cut. For a window or door you hang the sheet right over the opening in the framing and zip around the rough opening framing clockwise. No real measuring, quick and easy. I bought the M18 drywall router last year and love it. Don't use it much but it paid for itself the first time I used it.
