Thread: DMT 8C or ATOMA?

I'm thinking of buying a diamond stone for lapping. I have three Naniwa SS stones (1, 3, 8) and three welsh slate stones (DT, Yellow Lake and the Purple stone) and due to the shipping cost on the DMT stone it will cost around $85, meaning that I can get an ATOMA stone for only $5 more.

Which is generally thought to be better for lapping? And which ATOMA stone would be best (140, 400, 600 or 1200) for lapping these stones?

Both will serve you well,
the Atoma in a 400 or the DMT8C which is 325
I have no experience with the Atoma however from what I understand is less prone to the suction as the surface is not continuous.

Where are you located?

I have a dmt it does tend to stick to the hones while lapping.. To avoid that problem I just lap under running water.. The atoma is lighter in ur hand then the dmt and may be a lil better to handle but both will suit you well

I've got the Atoma 1200 and it is bad to the bone. Far outdoes the DMT IME.

Say whaaaat? The DMT325 is $47 + shipping maybe $8 throw in the stone holder (not needed) for another $16 and its still only $71.

Atoma is an easy choice for me.
Any of those will work but the 140 is overkill unless you have banana shaped stones to lap .

The Atoma diamond plates are a dead solid choice. I wore out two and a half DMT 325s before I tried the Atomas. They work better for sure.

The DMT 325 is good for grunt work repairs on razors needing a lot of metal removed in a hurry. I used it for lapping for quite awhile. However, I now have the Atoma 400 and 1200 and they do most all of my lapping and are a milled surface providing a very precise flatness.

Thanks everyone for the advice. The ATOMA is certainly looking desirable. I have a very cheap 6 inch diamond hone that I have used to lap slurry stones and my nagura. It sticks and I don't mind that, but if the ATOMA lasts longer then that's a strong recommendation.

I'd like a link.

8" Dia-Sharp Diamond Stone - $53.99, shipping estimate is around $30 (US to Australia) could be more. If I can get an ATOMA stone for only a little more it may be much cheaper in the long run.

Plus if the ATOMA 600 or 1200 can work for lapping it's a lot more useful as a hone than the DMT 325

I find them pretty useless as a hone tho some may use them that way. To me it feels like honing on 9 miles of bad road.
I just use a 320 grit Shapton Pro for heavy work & leave the Atoma for lapping
