I picked up a Milwaukee at an auction that works great for boring into
granite.
However I dont know what the bits are called, just that they are expensive
at even Home Depot. Which ones does it use or do I need to give the model #
?
Im going to be doing lots of drilling. Building a garage on solid ledge just
a foot below surface and will be pinning the foundation to it.
