Bubbling rock drills?
I'm looking to get a drill to make bubbling rocks. I know they are expensive and so are the bits, so that's not an issue or a surprise. What is the best option out there? Hand held the only way to go? Do press style drills inhibit size of rock too much?
I'm usually drilling 1.5 - 2" holes for Flex PVC. Stones vary, but usually in the 3 - 6' range size, often up to 2' in drilling depth.
In my search so far, often been told Bosch's hammerdrill is the best option out there.
Thoughts and/or suggestions? Thanks for any input.
