Tools drill bits for sanding resin, paper clay, epoxy and sculpy?

    1. my mum was awesome and splurged on a flex shaft drill for her jewellery making since i mentioned that it would also help me to make dolls as well (omg go her ;u;!)

      but i am a bit at a loss as to what material drill bits would i want? like would diamond point ones be good or should i also grab something else? (like the ones that look like they are made of stone) would i get the ones that look like sandpaper?

      i want to be able to get a final finish with these for casting and just general shaping or at least a surface that would be easer to get to a final finish....

    2. The ones that look as though they're made of stone are the ones I find myself using the most for general, all-over sanding. The metal ones coated in diamond dust or whatever are useful for fine detail, too.

      But I don't know if you're going to be able to get a final finish from any Dremel bit. IME, even the slowest speed settings are too fast, and the bits do not come in a fine enough grit. You can probably get pretty close and then do some more coats of primer and hand-sand for the last parts, though.

    3. HystericalParoxysm thanks! do you know what bits you have (like what colour they are?) since i know they have blue, red and white and are different depending on that...

      what about the wool type drill bits? they seem like they could do a nice polish ? or are they not hard enough to take stuff like resin?

    4. I don't think the colour coding is universal - perhaps to a particular line, but I have yellow, pink, grey, and white that all work well. :) I get big cheap packs of 'em on Amazon. Just have to make sure the "stem" bit on them will fit on a Dremel cos it's easy to get ones that are too big by accident.

      The wooly drill bits polish to a shine (especially on top of primer) but are very very soft, not enough to take off much material, and most of the time you need a sort of eggshell finish, not shiny gloss.

    5. reguardless of which bits you get (I like the diamond ones myself and get them cheap on ebay) this is the most used thing I have for my dremel!
      http://www.amazon.com/Dremel-4486-MultiPro-Keyless-Chuck/dp/B0000302ZV/ref=cm_cd_al_qh_dp_t

      this allows me to use ALL the different shafts up to 1/8" and also to use super tiny drill bits down to 1mm!

      For finish sanding I have found that the white "polar" blocks used on acrylic nails are usefull for the stage in between 600 grit diamond bit and the 1000/2000 grit auto sanding paper.
      Honestly I found so many useful tools once I started doing my own nails! lol
