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

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 .

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.

Have received the bits - thank you not used them yet but look great for purpose- thanks

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!!

I buy a lot of these- so much so that I’ve only just started to use this box that arrived in May. Out of a box of 30, 21 are utterly useless. This is very disappointing as previous purchases have a much lower defect rate. All the failed drills due not have a properly formed tip, fail to catch into material and fail to bore at all. Sadly outside the return window but after many boxes I shall be looking for an alternative

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..

Utterly useless. I’ve ordered previously and have had no problem. This time, the drill bits just skidded all over the place nd broke. I don’t know whether there’s been a bad batch or what, but I won’t be ordering again. My jewellery making has now grown to a halt

Stabile Bohrer die gut bohren.

Perfectas para bisutería; cumplen su función

Para mi maquina, el vástago era muy grueso

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.
