Re: Re: Re: Drilling small polished stones for stringing?

I've run across the same difficulty in the past, even using good quality drills. Seems some rocks just don't want holes in them, very hard or tough mtl. One solution is to use copper nails [I use 5-penny in size and cut the heads off] and apply grit [I use 80] manually. Certainly not fancy, or fast, but substantially cheaper in a tough rock situation. I use the equipment and method essentially the same as you do. If you frustrate out, or start going broke, give it a try. Good luck.
