Bill,

I know "rent a hammer drill" is not the answer you're looking for.

Still, it is the best advice for your situation. With a hammer drill,
you will NEVER have to stop to bust up the aggregate. A hammer drill
will bust right through on its own.

The amount of time and money you spend running around looking for a
star bit will more than offset a 4-hour rental on a hammer drill.

Drill 20 holes with your regular drill, using the star bit every time
you run into a pebble. Then drill the other 20 with a hammer drill.
You'll wonder why you even bothered with the star bit.

Thanks. The job was finished with the tools at hand.
