From http://www.toolocity.com this video demonstrates how to drill 1-3/8" holes on 3cm (or 1-1/4") thick granite with a polisher and our Monster Dry/Wet diamond core bit. The bits can be found at http://www.toolocity.com/monsterdrywetdiamondcorebits.aspx
The video only demonstrates our way of drilling granite with our tools. We by no means claim to drill the best holes on granite. The Pros can always do better. Your comments are welcome.
The Monster Dry/Wet Diamond Core Bit 1-3/8" is $39.50 and lasts for dozens of holes. For questions and more diamond tools for granite fabrication, please visit our web site at http://www.toolocity.com or call us at 800-980-7808.
