that's not a router bit..
it's a rotary burr...
DO NOT use it in your router....
burrs are used in Micro Motors, Pendant Drills, Flexible Shafts, and hobby rotary tools such as a Dremel.....

it wasn't stuck because it was burr but because it was left in the router for who knows how long...

That was my first thought, had to be a deburrer. Amazing what can be found.........I can't imaging that being used at those high speeds. Maybe we should try some small grinding wheels next.

I have those for using in a straight grinder (and some for other rotaries) , but for interest sake, why not use it in a router?

what's the RPM of your die grinder???
that style of bur is intended for low speed use and using them in high speed tools is out of the their design parameters...
high speed burrs get pretty pricey...

Like Stick said Rotary Burr. You use them in a die grinder for tool and die making. We used them for porting and polishing cylinder heads and intake manifolds at a machine shop I used to work at.
