I have a dremel and I wanted to get a bit to enlarge the hole on my
beads. A lot of the bits I’m looking at in the size I want will have
a shank that is the same size as the cutting head. I’m wondering,
what is the smallest diameter a dremel rotary drill will accept?
I’ve had this drill for a few years, the manual is long gone and the
website does not offer an online download for my model (it’s a 400
I have some shell beads andstone beads with holes way too small for
the gauge of wire I’m using (19 or 20 gauge). The shell beads are
soft enough that any kind of drill bit would do (or so I guess), but
I have some tiger eye beads with a pinhole sized hole. What is tough
enough to work on tiger eye?
Note From Ganoksin Staff:
Looking for a multi functional tool for your jewelry projects? We recommend:
a diamond bit is tough enough. i dont know i they have it for the
dremel though, in that small of size. ive been having a hard time
finding things for the dremels other than the small selection they
have on their website. :[

Some dremels have a collet - a separate piece of metal inside the
part you screw tight onto the bit. There are different size collets
so you can exchange a small one for a larger one to fit different
size shanks. If you are going to drill stone, put an inch of water
in a bowl or small pan, and hold the stone and tip of the drill bit
under water. I would advise using a bit with diamond grit. I have
gotten packs with various shapes and sizes bits at Harbor Freight
that work well for this.
Includes 4 collets–1/8-inch, 3/32-inch, 1/16-inch, 1/32-inch–and
collet nut Allows you to quickly change collets to accept bits with
shanks of 1/32-inch to 1/8-inch For use with most rotary tools Not
for use with EXCEPT models 1, 2, 260, 270, 280, series 1 or earlier
I Have even seem them at the chain hardware stores. They also make a
keyless chuck. Just google there are lots of different types out
you can take off the end and remove the collet and get a chuck to
replace it, i cant remember what size it will go up to but you can
use more or less anything in it then, i had one for mine which i
still have somewhere, id say it goes up to at least 5mm (dont quote
me on that) but you wont have any problems with burs etc in it and
they are very cheap to buy so its well worth it oh, by the way im
not sure if its an original dremel part, it could be one of the
companies that make things that fit dermels, but anyway well worth

the smallest size collet they make is for a sixteenth shank, but
twist drills for instance, come in all size drills with the same size
shank, this is their collet page,
Thanks I searched ebay and found a seller I dealt with before
with great results.
Their Widget Supply and I never knew they had a ebay store in
addition to their online store.
I got 5 different sizes in packes on 10 in each size, 5 collets in
1/32" and 2 pairs of wire cutters for $33.79 (includes S&H).
So far the 1/32" colletholds the smallest of my twist diamond drill
bits, a #72. Will power it on later tonight and see if it stays
still while being used.
To keep the bead from spinning (this is a round bead), I’ve been
using a pair of full sized needle nosed pliers that have concave
grooves that form a hole when closed. What purpose they were meant
for I don’t know, but I put a thick layer of masking tape around each
jawto protect the bead from scratches and to grip.
