Thread: What to get for Flattening - Granite + Sandpaper or DMTd8c

Can't speak for everyone, but for me, yes!

I have 2 DMTD8C's and both are warped from end to end making them high in the center. Not a lot, but enough that I've chosen to not use them for lapping. I use them for quick removal of metal when fixing chips, etc. on razors.

My go to lapping plates are the Atoma 400 and 1200. The Atoma's are an aluminum plate milled to an exact flatness and then have a thin metal sheet with diamond that's attached to the aluminum. The diamond sheet can be replaced if damaged and you can get another sheet with a different grit, i.e. 1200 and attach it to the opposite side and have two in one. Also the diamond pattern on the Atoma is less given to stiction.

Here's a link with info and a trusted source. I've bought from them several times as have many others here on the forum.
