I love this bit. it has an 1/8th in shank and a spiral configuration with what appear to be roughing flutes. has a split tail tip for plunging. Seems to work well on a variety of materials. Anyone know what its called? Better yet where they can be purchased?

Thank you very much!

That looks like a PCB router bit. You can find them fairly cheap on eBay.

It is a bit different from a pcb bit. A pcb bit is referred to as a corn cob bit and is more like a burr. This is more like an R&F end mill. They corn cob bits don't really have a continuous flute geometry whereas the chip breaker bit does.
