Diamond Coated Rotary Ball Point Burr

[rail_nut]

I need help locating a supplier for Diamond Coated Rotary Ball Point Burrs
 0.8 mm = 0.032” diameter
3.2 mm = 0.125” diameter shank
Previous supplier was "hobby-time bastel-system gmbh"
They seem to have gone out of business as no answer at their p0hone number.
Any ideas for another supplier of small diameter diamond ball point burrs would be appreciated.

Not sure of these sizes, but Harbor Freight:

Did you try the jeweler's tool suppliers, like Rio Grande or Gesswein?

(this is a whole page of different ones)

https://www.gesswein.com/abrasives/diamond-tools/burs-drills-points/diamond-wheels-points-3-32-shank-db-2-0-db-2-0/
(this is for a .032")

I don't think these two have both diameters you want but they are close. 

Be aware, these all have 3/32" shanks, which is smaller than the standard 1/8" Dremel shank.  You just need to
have the right collet for 3/32".

To All,

I had a great alternative asking my dentist for "old" and used drill bits.
Sterilized, they come in all shapes, diamond coated, teeth like a mini router and in a de-burr type of coating.
Works great on all materials, even grinding N scale locomotive frames....

Better to roughly right, than to be exactly wrong...

You can find all types of dental burrs if you look on the evil bay. I do not use too many of the diamond type, they seem to get clogged up with the soft metal used in the frames. The regular ones will cut brass and the frames with ease.

Thanks for the ideas and will try them out.
I didn't have much luck with ebay as ball type burrs are in sets of various sizes or are more drill than ball burr.
