Does anyone own a cone bit? Is there an advantage to the regular step bits?

What you have pictured is not a true cone bit it is more of a reamer,Do a google search for cone bit image
Here's a link to all you will ever need to know about bits , description image and uses.

we use step bits with replaceable tips
It looks to me like an step bit would leave an even hole in the #12 gauge metal it drills through... this cone bit looks like it would leave an sharp angled cut which may cut someone installing the connector. I've never seen one with no ridges...where did you get it, or was it grinded down?
I bought 2 unibits 20 years ago. Burned em up within several days . Being a pack rat I still have one of them on the van because I can not bring myself to throw a $50 ruined bit away.:slaphead:

I've used the single flute countersinks for years, most of which are the same concept. As a bit, the tapered hole would seem to be a disadvantage ... but what do I know?Does anyone own a cone bit? Is there an advantage to the regular step bits?
Someone told me unibits could be sharpened.
Never seen it done, though
