So, yes this will be compatible with your rotary tool. Happy Drilling!

Hi, I want to order diamond bits to drill 1mm holes in 500um thick borosilicate glass wafer. Could you please tell me if 0.75mm diameter drill bit would be perfect for that or not. Also, what other items I would need to drill hole along with drilling machine. Besides, could you suggest me which drilling machine would be sufficient for this job. Thank you. Best Regards Deepika Sharma

Hi Deepika,

Good to hear from you. We recommend using a Dremel 3000 drill with a Dremel Multi Chuck and use either the small diamond drill bits or the small diamond core drills. If you are new to drilling holes in glass we recommend trying the core drills first. The size of the core drill indicates the size of the hole you will achieve, so if you need a 1mm hole, you will need to purchase the 1mm diamond core drills. All the best with the project.

I need a drill and small bits to put small holes into pebbles, these need to be wet (sat in a shallow tray of water to do this) is this item suitable? Thank you Samantha :)

Hi Samantha, Thanks for your enquiry.  Yes, we have just the tools. Use a Dremel 3000 drill with the Dremel collet nut kit or a Dremel Multi Chuck and some small diamond drill bits. You might like the Diamond Drill Bits set for your Dremel. This set contains 2 x small diamond drill bits and 2 x small diamond core drills, in different sizes, all ideal for drilling holes in pebbles.  Our article on How to Drill Pebbles might also be helpful for you. If you want to buy the diamond drill bits indiviudally without being part of the set please click here.
