1mm Diamond Drill Bit Set 30 pcs Compatible with Dremel Cylindrical Burr Kit Jewelry Beach Sea Glass Shells Gemstones Lapidary 30pcs. Case Included

Well it took 2 bits to get used to using a dremel! But the this bit has done 10 pieces of sea glass. So I can't complain at all! The drilling itself is a knack but I used a plastic Chinese food container with a thin piece of wood and natural sponge immersed in water. Fab!!

Great. Drilled through my sea glass wonderfully. These are 1mm, so obviously not much diamon on the ends and you may have to use more than one for the job. Very happy with them.

Very pleased with these drill bits. You do get the odd dud that doesnt drill in the box but still good value for money and each drill bit lasts before the end becomes too blunt. I would recommend.

I have used this brand of diamond bits for a couple of years of now. I use a 1mm bit to drill sea glass for making into key rings & other gift items. Never had a problem with them (maybe one or two in a pack of 30 that didn’t ‘bite’ very well on the glass, but generally happy with them. However, they’re obviously being manufactured somewhere new, as the last two packs I’ve ordered are ALL useless - not one out of the 30 made even a tiny indent in the glass - so had to return as they weren’t fit for purpose. I’m now going to have to try a different brand. I’ve previously recommended Drilax to lots of other crafters/jewellers, but not any more, they’re useless for sea glass.

Take your time, start at an angle and then vertically and keep it wet, we drilled in dish of shallow water. Took about 10 mins to go through 4mm of glass, could have been quicker but didn’t want to apply too much pressure .

OK quality for the price, I suppose. They are incredibly easy to break and I'm not sure about the diamond content. It takes an age to get through a few mm of glass. I'll look outside Amazon for the next lot and expect to pay more for something of better quality.

Last a lot longer than I expected due to the price

Bought these for drilling seaglass. They are very effective.. easily pass through even quite thick glass..

Stabile Bohrer die gut bohren.

Perfectas para bisutería; cumplen su función

Subito provate e ne sono rimasto entusiasta! Ho già fatto 7-8 pietre di mare con una punta e ne rifarò non so quante altre ancora!!! Sto usando un dremel a colonna, sempre a bagno in acqua, discesa molto lenta, velocità dai 15/20000 giri.

Sehr gute Service. Gute Qualität. Funktionieren wie erwartet. Hinweis bezüglich nicht trocken verwenden war sehr ausgeprägt und sehr nützlich. Im Zukunft wieder.

Algo caras pero buen resultado (es verdad que algunas no taladran bien pero en general, mucho mejor que juegos similares de otras marcas).
