Thread: 3m Cerium Oxide lapping film

Abrasives Solutions for Surface Finishing : 3Mâ„¢ Lapping Film, 562X Sheets

Now if we could just find a place to actually buy it from.

Interesting looking stuff. .5 micron? I saw a place online where you can buy a pound of .3 micron cerium oxide for less than $25 if I recall correctly. I have not ordered any yet and would have to dig up the link.

I have some of these sheets and they can be purchased at Japan Woodworking.

Chris, if you find the link, I'd be really interested in it. In addition to using it on a paddle strop, I'd like to try it as a polishing medium in a vibrating polisher.

Thanks, Gunner777... Are they Cerium Oxide? The web page doesn't say.

As a courtesy to all, this is what I found recently. I haven't ordered from this company, it's merely a result of Google searches.

I'm actually not sure but they are very good and I can tell you I used these a lot before buying my first hones and they worked very well and gave the razors a very nice edge.
You could give them a call and see if they are Cerium Oxide.

Gunner777 and ChrisL, thank you very much.

Gunner777, I'm pretty sure that's the lapping film I have, too. It's really good stuff. Some guys have been talking about Cerium Oxide a lot lately, so I'm curious about it and trying to find a source of it on a lapping film, in a paste, and in a powder, all at the .20-.50 micron size range.

Thanks to ChrisL, I now have a source of the powder. Now if I can just find a place that carries the 3M .50 micron cerium oxide lapping sheets.

Glad I could help. That's what I'm here for.

My pleasure also--that's why this is such a great place plenty of people to help out.
