@Superburban Thanks!
I had never seen those up-cut/down-cut router bits before, you taught me something new.
Here's a couple references:
What the heck is a compression router bit?
Compression Spiral and Spiral Solid Carbide Router Bits
Apparently often used for CNC routers in MDF and plywood to reduce splintering and tear-out on BOTH faces.
Although they do not look like the pictures from the start of this thread.......those just look like poorly made drill bits that got jammed and then "rearranged" themselves.....
