Free router bits

I have 8 brand new (still in the wax) router bits if anyone can use them. They are marked as “ONSRUD 40-118 5/16 ccf” which means diddly to me. It appears they are are down-cut spiral 5/16" diameter, but the bits have a 3/8" shank. My machines will not accept the 3/8. I have already checked with @squarenuts to see if the woodshop could use them. Maybe metals? Anyway, reply if interested.

If your router has a ½" collet then an adapter such as this one from Whiteside would allow you to use these bits.

Thanks Bill!
I didn’t know this existed, but makes total sense. Perhaps I will keep a couple of these and hand off the rest.
