600 Mesh Sintered Diamond Burrs?

Recommended Posts

I am looking for a good, balanced, 600 mesh Sintered burr?

 

Did noticed "Graves" and "Diamond Pacific" carry them. But are veeery small.

 

I have not discussed this with any carvers:

 

------------ Has anyone tried these or know of a supplier for the carving trade?

 

----I have seen some very nice tools in shop photos of professional gem carvers.

 

-------------=Threaded Cameo Lathe tools look better than anything/so far.

-----------------= But have no idea where they were manufactured?

 

 

--------=I have used all the electroplated tools available and they work well.

---------Kenneth is right on- that Daniels electroplated burrs are very good.

 

------------=It is the elusive/completely smooth pre-polish I am hunting for.

 

 

~~~~~~~~=Chime in if you have info.=>

 

-------------=James

james,at one time i tryed sintered diamond tools,they don't wear even and get bumpy and can ruin what you are working on.allof the ones i had i threw away and went back to the plated tools.Lopacki is the best place to get your tools.the plated 600 grit tools need to be run at low speed and they will do fine.best regards to all,kenneth neaves

I'm hoping that Daniel will chime in on this subject, because I feel sure that he knows of some products that I don't know about.

 

I've been working on some pieces that are larger, and out of necessity have been making larger bits myself. I'm primarily using brass or wood with oil and diamond powder. It is possible to charge felt and bristle wheels for smoothing purposes also. I'm currently working on a piece of lavender turkish jade about 3.5" x 2" that is concave, and the wood, oil and diamond has been working well for me. I'm working on a slightly smaller piece of chalcedony at the same time (MUCH harder than the jade), it's slow, but it works. I used grinding stones to do the initial carving out, and got the bumps out with wood, oil and 200 grit diamond. I'm still working with the 600 grit right now, hope to move up to 1200 today.

 

I think I know who you are James. Didn't you have a really beautiful piece of shrinkwood on Etsy? And don't you make the really neat water cooling spray system that's inexpensive? (My friend has one)

 

Craft stores like Michael's and Hobby Lobby sell hardwood balls, wheels and misc shapes of turned wood for not too much money (I don't have a lathe, or I'd make them myself). If you like, I'll try to post a picture (if I can remember how!) of my set-up, I've built a point carver/grinder/polisher out of an old arbor.

 

I couldn't find any pictures on the internet of the cameo lathe bits that you're talking about, if you can, post a link.
