Hey! I just got my dremel, and for a girl I absolutely love it! I make jewelry so I bought it for that purpose. I'm working on some rocks, but I need to drill holes in them so I can string them! What's the BEST way of doing this? It doesn't have to be perfect or anything.

I make jewelry also, using stone, glass, bone, metal, wood.
Use diamond bits... they go through anything. I use a small bowl of water, holding a stone underwater to act as a cooling lubricant. Don't let the bit get hot or the diamonds drop out of the matrix and the bit becomes useless. I drill with a medium speed and a kind of pumping motion; pushing hard to dig in, then backing off the pressure to allow the water to rinse away the stone dust, push hard then easy, hard then easy. Take a break now and then to check your progress. Some stone like slate and limestone are easy and drill real quick. Other stone like quartz, corundum (rubies, sapphires) take a while to get a hole through by hand. Using the drill press attachment helps to put the pressure to the bit and makes the job fast and easy. There are a couple of videos on YouTube that show drilling glass and stone.





cut to fit, file to match, paint to hide

Excellent recommedations. My daughter is beginning jewelry making and we're going to drill through some stones. I'm curious as to where you found the diamond drill bits that were long enough to go through a stone that is perhaps 3/4 of an inch thick.  Can you help me out there?

Gratitude!

Allow her to show her creativity, since sometimes over guidance can work in a negative way. Giving access to show such skills at a very young age is very good and it can enhance cognitive skills in kids. Good parenting everywhere.

I did laminate flooring and my home is now brand new.

****o this is Beth from Dremel.  I always have this concern (scare actually), when I read that consumers are using "water" with a tool.  This is something that Dremel does not promote!  There is a chance for shock or worse yet, getting electrocuted!  We never suggest mixing water with Dremel!  I know there are many of you that want to drill holes in rocks, and yes we do make some diamond wheel bits, but ours are called out for applications more for doing fine detail work, engraving, carving, doing touch-ups and finishing.  As you can see ... we do not mention any drilling.  We know this type of application would make the bit hot, therefore, it's something that we don't suggest.  I believe a lot of drilling in rocks is done more with a pneumatic tool.  As always, just remember to be safe!  If you have any further questions, please feel free to contact our Dremel Customer Service Department on the toll free phone number of 1-800-437-3635, Monday-Friday, 7:00 am - 6:00 pm, CST.  Any of us would be more than happy to assist you.
