Strange Router Bit

[tabbypurr]

Picked this up among other things:

has 9 cutting edges rather than 2. The cutting head bolts onto the shaft, and the head is one solid piece of material, not TCT on steel. Since steel & TCT are both magnetic I can't tell for sure which this is.

What is this? A superfast TCT router or some old school stick-it-in-your-B&D-&-pray steel router?

Maybe for doing a roundover on granite worktops, but without a bearing, it'd need to be used in e.g. a CNC mill.

I don't see what else it could be. It can't be a countersink, too large a central area (about half inch across there) plus the wrong shape. It's roundover shape except that the widest bit doesn't quite go all the way to 90 degrees. Odd!

Or a table router. Or a fence router.
