Can they be used on rock? Would like to make small holes in rocks (difrent kinds) to make jewelry.

Yes! Diamond coated drill bits cut through concrete, rock, ceramic, porcelain, terracotta, glass, gemstones, marble, granite, etc. You must keep the gemstone or rock lightly submerged in a pan of water with a piece of wood or rubber below for support. Drill at an angle not at 90 degrees. Once hole has started, gradually tilt the Dremel back to 90 degrees for a straight hole. Some glass may need halfway drilling and repeat on other side to prevent cracking. No pressure, firm hold, angled start, halfway reverse on glass only.

Can these drill into glass products other than seaglass? I would assume so but wanted to check for something such as glass bottles.

Jacob, I haven't tried drilling into glass with these. They are quite tiny in their circumference and I was worried that they could do the job on glass, so I ordered Dremel compatible larger diamond bits that are designed to drill glass, tile, and stone from DiamondBurs.Net LLC and they work great on wine bottles!

why does this not ship to canada?

contact Amazon for their policies

can it be used on pearls?

I use them for drilling my sea glass pieces. I would think as long as you go slow you would be ok.
