I'm new to this process, so I'm still researching. My question is: what drill bits do you recommend for drilling sea glass in particular. Not expensive ones as no doubt I will go through them quickly whilst learning. URL links to sales sites would be great, if that is allowed. I have just bought a Dremel 3000 and I am waiting for a Multi Chuck as the one bit I was recommended by Cooksongold falls out of the drill with the current attachment

Thank you
