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

Last a lot longer than I expected due to the price

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.

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 .

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!!

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

Bent out of shape, didn’t eleven get through sea glass

Couldn’t get my usual brand so bought these, not very good quality and even though drilling underwater very ineffectual.

Worked really well for drilling a small hole in sea rolled glass for jewellery. Used with a standard hand held power drill. Broke the first one coz I pressed to hard but did 10 holes with the second one no problems so these should last me forever.
