Can't Understand What A Tool Post Grinder Is Good For?

If you want to try the Dremel on a tool post mount, the Flex Drive that I have fits my 1/2 inch Boring Bar Tool Post Adapter very well.

I was going to make an adapter, but this makes the most sense for a home shop. The shaft can be removed, then both the holder and the flex shaft can be used for other tasks. Just ordered a shaft from ebay for $18.
