Drilling holes in beach stones to use for beads

Once you have a achieved a small divot, drill through the stone in with your cylinder diamond drill bit. Unless your stone is very small, avoid any bit less than 1 mm. The .75 mm bits have a tiny shaft and break often. The 1 mm bits have watches a reasonably strong shaft.To make sure you don’t drill through the bottom of your container, put a couple of pop sickle sticks under your stone. Hold the stone under water, on top of the pop sticks. Use clear water so you can see what you are doing. The top of the stone should be just barely under water. As you drill, a long tail of dust will drift off from your stone in the water. Press a little, pull back a little, and get a rhythm going. When you get 4/5ths of the way through, turn the stone over to see where the hole is going to come out. Mark it with a sharpie, knick that place with a ball bur and start drilling from the back. When the hole meets the other side, everything else becomes easy. Widen the hole with successively larger (cheap) diamond drill bits, drilling under water. I find a 2.5 mm hole holds a nice rivet and makes a nice pendant.Hi, I am Aftab Ahmed an IT student in NUTS University Islamabad, Pakistan.
