Hi Kristina -=3D20
Go to eBay and search "diamond burrs" and "mounted diamond points" to =3D
find a plethora of choices in various sizes and shapes. If you are =3D
using a Dremel, be sure to get the ones with the 1/8" shank. I find =3D
them to be superior to and less expensive than the silicon carbide =3D
burrs.

You can buy silicon carbide bits to fit a dremel. Lapidary shops sell them =
and I think I've even seen some at Walmart. Ebay is another place that woul=
d probabably be a good source.

These are the silicon carbide grinding wheels I use with my Dremel tool:

Grey is the roughest.

Hello Robert;

I have bought 4 of those bullet grinding stones at a flea market for
50 cents a piece. They come in 2 colors (grey white and pink) The
seller could not tell me if they are different. Do the colors
signifies coarseness?

Thanks in advance

Not coarseness, but hardness. Pink is aluminum oxide and grey is =3D
silicon
carbide. AO is harder then SiC.

Coarseness relates to the size of the grinding particles in the stone. =3D
Both
the pink and grey are quite fine (small grinding particle size).

The stone I use is Model 952 ... it has large particle AO so its quite
coarse. It grinds faster and lasts a bit longer then either the grey or
pink stones. =3D20

You got a good deal. On the Widget site the pink stone sells for $0.97.

Hi Bob,
Thought grey color is aluminum oxide and green is silicon dioxide.
This is just with my experience. Perhaps there are other brands with
different colors.

I have bench grinder and Dremel tool.
On bench grinder I have aluminum ox. On one side I use for metals.
On other side is a green colored silicon carbide wheel I use for
clay/glazes.
Tried the aluminum wheel on glaze one time - it did nothing.
Silicon carbide wheel eats right through glaze.

Same with Dremel tool - grey & brown grinders do nothing to glaze.
The green colored ones are SiC and work well on the glaze.

Think these green SiC grinders are termed "sacrificial" as a layer of
material is lost during each grinding.
I do crystalline glazes and have gone through a few grinding wheels over th=
e
past few years.

FYI - When the 6" grinding wheel gets worn down, I use it on it's side to
grind glaze drips off Advancer kiln shelves. Also works on the cheaper
nitride bonded shelves.

Bill -
The green silicon carbide wheels are known as "green wheels." The grit
sharper than regular gray or black silicon carbide, but it is a softer
matrix, thus the way it wears down especially if someone makes the mistake
of using it on ferrous metals. Standard silicon carbide grinding wheels ar=
e
medium to dark gray, and are more durable but don't cut into fired clay and
glaze as well as the green wheels.

Aluminum Oxide can be white, pink, or brown, and silicon carbide can be
green, gray, or black. A less common grinding wheel is aluminum oxide
zirconia. Aluminum oxide is the best to use with ferrous metals and
stainless steel. Aluminum oxide zirconia cuts faster on ferrous metals and
stainless, but is a lot more expensive. Silicon carbide is best for
non-ferrous metals, masonry, and ceramics.

For a Dremel or Foredom tool, I still say that the diamond burrs available
on eBay or from jewelry suppliers are better than any of these. To check
out an example, look at item #290510380579 on eBay. Note that it comes fro=
m
Canada, but the total cost including shipping is only $30, which is an
amazing price for a set of fifty diamond burrs. I have purchased a number o=
f
these sets, including the ones shipped from Hong Kong, and I have not been
disappointed.

Note that these have the 1/8" shank to fit the standard Dremel and Foredom
collets. I have a Foredom flexible-shaft tool that I loan out to my
students and it gets heavily used. We get very good wear out of these
diamond burrs.
