I think I've seen versions of this little hummer, too. You stick the wire in the end and feed in enough wire so that one of the following occurs: 1. You have one of the early versions of these bits, properly called a "cut off bit". It slings a ~1/8 inch chunk of *bare* wire *somewhere* into your nail bed. Or, an inch or so of insulated wire is sticking up through the top slot, and that much gets cut off and thrown *somewhere* when you pull the trigger. But it's insulated, so no problem, eh? Well, not *most* of the time. Ho hum. We'll find it if it does anything outrageous... 2. You have a model that puts all the wire fed to it on the post. (You *do* like 3/8 inch long wraps, don't you?) It only throws the *empty* Kynar insulation frag *somewhere*. Again, no problem. 3. You have a model that EATS the part of the wire that is "slightly longer than needed". Chomp, chew, smack, ...more...??? but I am being unfair, I suppose; the particular bit you describe likely *is* what you say it is, and we can at last wrap in peace. I only wanted to warn the unaware that there are many, many, versions of earlier searches to this particular form of excellence, and you guys and gals (see, I do learn from the doings of others) better find out *exactly* which tool Larry is talking about. But I ain't proud - *I* am going to write and ask! Thanks, 'brders.
