What is the name of this drill bit?

I want to say "Spade bit" because of the shape, but that's taken by the commonly found boring tool. This tool is much better for widening a 1/2" hole to a 3/4" as I didn't have a center reamer of the correct size. This bit was made by Miller's Falls, part number 800-15. I suppose it looks most similar to a glass and tile bit.

WELCOME TO THE FORUM

Glass and tile bits are carbide and pointed.

Got it. Not a glass bit.

So what is this bit, then?

That looks a lot like what my dentist used on me last week.

Since it doesn't have a point, it's seems that it can only be used to ream out or clean out existing holes. Also since the flutes are straight, it has to be light density material. Hardwoods, glass, plastics would rip apart those flutes no matter what speed you use. Used on styrofoam?

hmm...

Are you sure it's even a bit. No point, no visible sharp edge, nothing to pull out the waste. If it is a bit, it's never been used, cause there are no burrs on the shank from slipping in the chuck, and that sucker looks like it would slip. I'm wondering if it isn't a part to some other type of mechanism.

Doesn't even look like a drill bit to me.
