VIFERRDiamond Drill Bits for Glass, 20PCS 1mm Diamond Coated Lapidary Drill Bits Solid Bits Needle for Jewelry Agate Sea Glass

These were delivered pretty quickly. Came packaged with a few other things I'd purchased from Amazon - no complaints. I use these kind of drill bits regularly to drill seaglass. These, like all others I've used, are quite delicate but, if used carefully, they do the job quite well. No complaints and happy with their performance.For anyone thinking of buying these, or similar to these - they do fit into a Dremel (I use Dremel 3000) however, you need a multi chuck for them to fit 👍

As you can see from photograph, the package contains sticky labels, not drill bits.

I bought these to drill holes in sea glass. Work really well and do not snap easily as long as you apply gentle pressure and drill in shallow water.

When they arrived was dubious as so flimsy so started to gently drill 3 snapped within seconds with hardly any pressure so I decided to by a proper one somewhere else

This drill bit worked brilliantly on seaglass

The shaft is so thin it is impossible to put it in a drill (it's like a needle)

If kept cool and wet when drilling these bits work really well.

I thought that these drill bits would fit into a rotary Dremel-like tool, but they do not. The shafts are VERY thin, and even with my rotary tool's smallest jaw it does not clamp. I wold be interested to hear WHAT tool these fit?
