Diamond files


I subscribed to this list because I don’t know where else to look for
this item, and it’s possible that jewelry makers might have some
insight. I’m trying to locate a retail source for a very fine grit (at
least 1000 grit) small, diamond flat file. Does anyone have any leads?

Thanks in advance for your help,


Pete, try Kirk Brock of Rock Solid Jade. He always has diamond files
and bits. He’ll be showing at the club show at the Merchandise Mart
during Denver shows, about halfway down aisle K.

Hi Peter- Most diamond files I have seen are much coarser than you
need but , 3m makes a psa backed diamond sandpaper that can be
attatched to a wood or metal sanding stick or dowel.They come in grits
from 200 to 1800 this might work for your application . Hope this is
of help to you.

I use four grits of flat diamond file made by 3M for stoning my
cloisonne enamels. These files are also available in half-round and
round shapes. If you only need a small flat filing surface, 3M makes
a series of interchangeable diamond disc pens; they also have discs
that stick onto a flat rubber mandrel [called the Roloc system] so you
can use them in a drill press or with a flex shaft. Rio Grande and
Stuller both carry a large line of 3M diamond products. You might also
want to check lapidary supply catalogs. If you can’t find exactly the
flat file you want, perhaps you could by diamond cutting paste of the
grit you need and apply it to an appropriate surface. Since I don’t
know what you’re working on, it’s a little tricky to be more specific.

good luck,

Hi Peter,

I’m afraid I don’t know where to find diamond files in as fine a grit
as 1,000; I’m not sure if they’re made at all.

However, you can make your own. Take a piece of ordinary 1/4" copper
tubing which is as long as you want the finished file to be, beat the
tubing flat on an anvil all except for say two inches at one end which
will be the handle. Then on a bench block or other piece of flat steel
do some fine hammering to get it as even and as flat as you can, and
finally file out the hammering bumps. Now you have a strip of smooth
even copper with a round handle at one end. Or you can start with a
sawed strip of, say, 3/32" copper sheet.

Once the metal is smooth and flat just barely moisten one side with
olive oil. Then apply two or three dabs of 1,000 grit diamond powder,
each about the size of a pinhead. Spread the grit evenly over the
oiled copper with your finger. Then press it into the metal by rocking
a rounded polished piece of agate over it. The hardness difference is
such that the diamond particles will quickly embed themselves into the

While it’s not as robust as a sinter-embedded tool would be, the
resulting file works quite well, albeit you’ll need to use it with a
light touch and re-charge it with diamond from time to time.

I’ve used the same basic process with copper wire also, when I wanted
to cut rounded grooves into a curved bracelet stone. Just hold one end
of the wire in the vise, the other with the pliers, stretch, apply
olive opil and diamond grit, run the stone over it to embed the
diamond, and voila.

Hope that helps,

Hans Durstling; this type of bench tip is what makes Orchid so great.
Thanks,I’ll use this too. John Barton,Images By JJ

hello, It is not possible to get a diamond files grain 1000. But what I
do is take double sticky tape, what they use for carpets on floors.
Stick on a paint stirring stick or any other shape you need an stick
with that very fine sandpaper or lapping film. Very sheep and worn out
make new ones.

Daniel Lopacki sells a wide variety of diamond files and at very
discount prices.

You will also find discount diamond burrs, drills, core drills, saw
blades, belts, polishes, powder, flat laps… and for those who love
really fine opals and hand work… Daniels’ fine strands of amazing
opal beads…

I am the web master of the site… and I use the tools, they are
excellent and cheap.

All the best in all things,

    Here's another option for making files or sanding sticks of
different grits. 

Different grades of silicon carbide wet/dry paper from the hardware
store can be glued to popsicle (craft) sticks with carpenters glue.
The craft sticks are available from craft stores like Michaels & Ben
Franklins (in the US).

A full sheet of wet/dry paper will produce about 50 sanding sticks
with no waste.

  1. Lay the wet/dry paper face down on a flat surface.

  2. Spread a thin layer of carpenters glue (Elmer’ etc) on the back of
    the paper.

  3. Lay the sticks on the paper right next to each other. 2 sticks end
    to end cover the full length of the sheet. Cover the entire sheet.

  4. If desired, a second sheet of wet/dry paper of the same or a
    different grit can glued to the other side.

  5. If gluing a sheet of wet/dry paper to the other side, place the
    2nd sheet face down on a flat surface, apply a thin coating of glue to
    the back side.

  6. Grasp the 2nd sheet by the edges and turn it over, placing over
    the previously glued sticks.

  7. Weight the entire assembly overnight or until the glue drys.

  8. After the glue has dried, use a razor blade or other thin blade to
    cut the paper between the sticks. Cut one side at a time.

It takes about 10 minutes to make 50, 2 sided sicks.

If desired, diamond paper from 3M (really, any kind of abrasive
paper) can be substitued for the wet/dry paper. Also if wider & longer
sanding sticks are desired, paint stiring paddles or other thin wood
can be substitued for the craft sticks.

Happy sanding!

Dave: I do the same thing only with pieces of plastic from blister
packs and such. I use contact cement instead of carpenters glue. I can
then cut the sheeets of plastics into thin (2mm) strips or wider with
a pair of scissors. The blister packs also come in some really great
curvs and hard square edges. I just wrap the paper around whatever
shape I have. I usually make 2 or 3 sheets at a time. Let the contact
cement dry on both the back of the paper and the surface of the
plastic then just stick them together. Makes a very durable and
flexible sanding media. Frnak Goss

I have three flat diamond files in the 1k & smaller range of grit.
They were a part of an estate I bought. The two 1k grit have labels
that read " Crystalite Products Diamond Hone" General Electric is
on the label, but not as maker of the tool, but perhaps the diamond
… The other hone is near paper- thin, 3 in. long, & no label.
They are wonderful in the right situation. My only clue about where
to look for them is that the previous owner was a retired electronics
engineer It was clear that he found a lot of good uses for his tools
and gizmos in making jewelry as well.

I hope that is helpful …
