Premium Diamond Drill Bit Cylindrical Burr Kit - 60 Pcs, Jewelry, Beach, Sea Glass, Shells, Gemstones, Lapidary - 1mm, 2mm, 3mm

This was my first time drilling sea glass, and these drill bits work perfectly! I drilled multiple pieces so far, and haven't had one fail on me yet. I'd strongly recommend watching a couple of tutorials to learn the right methods to use these tools, but they're great value for money and would happily but this product again!

i was aware that some reviewers had had problems with these, but i have to say that they have been absolutely fantastic to use, and i am sure i will be able to drill holes in a good number of pebbles before each one gives up. I think the key is to make sure you know what you are doing, and make sure you use some sort of 'burr life' to lubricate and prolong the life of the bit / burr. I found that these did not fit my pendant drill, but are perfect for my Dremmel, and use it in the Dremmel bench press set up. Of course you must sit your piece to drill in a shallow dish of water to cool the burr and pebble from friction heat, and please do take your time, don't push through too quickly. As long as you do your research and use these properly they will do a great job. I don't want to criticise any previous reviewers who gave this product a less than favourable review, but i think there may be a case of 'a bad worker always blames his/her tools' going on. SO take your time, do your research, and don't expect to be an expert if you have never done this before. I will definately buy these again.

Use with dremel, seem quite good if they don’t snap but they have been used for Sea Glass cutting and perform quite well. Don’t use too high a speed and they work better.

I actually love these bits. I use them on sea glass and they make light work of it. Second ones I have bought, last ones lasted me two years before replacing. Use in a multi tool.

Some drill bits worked but, some were crooked or simply did not penetrate. Not very durable.

So bad, they don't even drill thin plastic, all that happens is that the drill heads wear away as you drill creating the illusion of something happening, cannot drill soft materials let alone glass

For the price I paid I did not expect the item to be as good as I thought , great value

great fore sea glass making holes as long as you do it in water to stop bit from get hot

Buoni

Les forets sont de bonne qualité, assez solides. Ils conviennent parfaitement à mon usage. Je les recommande.
