Can I use the "Perforated" DMT Duo-sharp for lapping Norton 4k/8k, and Naniwa 12K?
My dad just picked up the DMT Duo-Sharp diamond plate, with one side 220 grit, and the other side 600 grit. It has perforations, or holes across the entire surface, which is different than the diamond plate most people recommend on this side, the DMT D8C. I just got a Naniwa 12k for Christmas, and I need to lap it. Can I use this diamond plate for this purpose? Is the 220 going to be to rough for the 12k stone (or the Norton 4K, or 8K), or could I first use the 220, and then move to the 600 grit to smooth it out a bit?
Will those perforated holes in the surface of the diamond plate not be good for a lapping plate(damage my hones)?
Also, can I use this same plate to lap a Norton 4k/8k?
Lastly, I know the 600 grit is not normally used as a lapping plate since there is risk of damage to the diamond plate. But if I did the majority of the lapping with the 220 side and then just did a quick touch up with the 600 side of the diamond plate to smooth over the honing surface, would this carry much of a risk with it to the diamond plate?
Thanks!
