Step 2Prepare your workspace
Attach the flexshaft attachment to your drill. Insert the collet into the flexshaft attachment, and the triple ripple diamond bit into the collet.
Suspend your drill
For this project, you will need to suspend your drill above your workspace. Many people buy a drill press to accomplish this, but I don't have enough room for one in my studio, so I just hang the drill from a nail in the wall using a carabineer clip. I sit in a chair with the water bowl in my lap and the drill at a level about equal with my head.
Fill your water bowl
Add just enough water to your bowl to cover the glass. Your drill bit should be the only thing underwater. Try to avoid getting the collets and flexshaft attachment wet, because they will rust.
Safety First!
Remember to put your safety glasses on, and if you have sensitive hearing, stick earplugs in your ears.
