I have used open end rivets in the past as well. Have some old stock copper and brass ones, which work well. They prevent the wire from wearing down the inside of the hole on softer stones.
These were from Tandy leather in the 1980's or 90's.

I was reading a thread in the tute section on drilling holes. I can't remember which one, but he used wire drill bits with diamond coating on the ends. That's what I bought to use. That and a bur to start the hole and prevents the bit from skipping. eta- here it is forum.rocktumblinghobby.com/thread/35856/drill-pendant |

All had a small, diamond dust, ball on the end. The shank was straight, with no groves. Works great. |

Cool. Only suggestion is to seal the hole area. Looks unfinished now. That would add a lot. Yes, I think the wrapped bail is wire wrapping. Some might not agree. Can you drill the hole before the final polish? Then it would be a polished hole. JMHO What do I seal it with? I could try to drill one before, the final polish. I would think it would have to be done just before that step so stone has shape I want... Any JMHO are greatly appreciated Hoping this hobby can one day turn a small profit to just buy more rocks or maybe not have to work 2 jobs........so I'll take all the feedback I can get Try Clear fingernail polish works well for small areas you want a gloss in. Use it often to gloss eyes on carvings when the eye is burned into the wood and you want the black to shine like its wet. |

Being the cheap thrifty person that I am I buy these bits from Amazon - $15 for 30 bits (50 cents each) can't beat it. I've never tracked it scientifically but depending on the hardness of the stone but I average between two and four holes per bit before they are toast. Sometimes when dealing with something very hard like Montana agate I might go through two bits to complete a single hole. smile.amazon.com/gp/product/B00AZMRZ4W/ref=oh_aui_detailpage_o02_s00 |

I got 3 and 1/2 holes out of it. Was wondering if this was normal. I'm ecstatic when I get 3 or more holes out of a bit. These bits are just coated with a thin layer of diamonds. Once that layer gets compromised the bit is garbage. They make sintered bits which means that the diamonds are actually embedded in the metal - so the bit can experience wear and still cut as fresh levels of diamonds are exposed. I don't cut enough to justify using sintered - I've seen them upwards of $25 per bit on places like jadecarver.com - I have not found a 1mm sintered bit though or I'd probably buy it. jadecarver.com/product-category/burrs/sintered-burrs/ |

I use the cheap 1mm diamond bits from Kingsley North. I buy 100 at a time to get the price down to $.75 each. I drill almost all pudding stone from Michigan. I get between zero and about a dozen holes per bit. When I tired to drill Lake Superior agates with the same bits, I used about two bits per hole. I might have to try the bits you use, Tommy. |

Was wondering if this was normal. Putting the stone on a piece of wood in a shallow container and covering with water helps by keeping the bits from overheating. I also like using glass (carbide) bits for drilling holes for knife pins. Not sure if they come small enough for the small holes you will want. |

The ones I purchased from Menard's, a Midwest Wisconsin thing, were about $.75 each, when purchased in 3 packs. Three sizes of diamond balls on drills. Have had them for 5 years, with minimal wear. Drilled and shaped about 100 stones with them. Also, did some stone engraving. Still going strong. Unfortunately, I do not know if they are available on line, as I purchased them on clearance, in store.

All we have here is Lowe's, HD, and OSH. All 3 didn' have much of a selection |

Missing Menard's, but I never agreed with the owners (John Menard) philosophy on store, environment, or racing cars, lol. The racing is a long story. Was a director at a facility who was a supplier of his for many years. Lowe's and HD, does not have the Dremel drill selection. Unfamiliar with the other. Amazon can be your friend for this, if you do the research and know what you want. |

OSH, is a California hardware store that was bought out by Sears and now I think Kmart owns them. Great customer service and I can usually find what I need. Ex works there so now I never go. I won't even talk about how crappy the service is at HD and Lowe's. So online shopping it is. |
