I've never used it on a Batt, but I use it on a Zinc+, it works great, you can move facets with it or cut small facets and it leaves a great prepolish, not near as good of a prepolish as 13k PCD.

What is the difference between the 8k PANPCD, and 8k Pandemonium (PANDMD)?
PCD is the acronym for polycrystalline diamond and MD is the acronym for monocrystalline diamond. The former manufactured by an explosive process and the latter by HTHP belt presses.

In practice, PCD is much sharper and faster than monocrystalline diamond. It's why 3k PCD is so fast compared to 3k monocrystalline diamond. Hope this helps -Allan
The testing results I have seen indicate that the removal rate PCD is 5-10% faster than MD up to around 30 micron nominal size when it becomes equivalent. PCD has many small sharp features whereas MD has one or a few edges resulting from octahedrol growth or cleavage. PCD does break down in size more slowly than does MD because no cleavage planes exist in the particle.

I am a little confused.
It may also be that I am looking at a different diamond.
I am looking to recoat wheels for the Genies for my club. I was talking to a manufacturer for diamond powder and they said that "MDP" diamond had fewer cleavage planes that PDC. The PCD was manufactured by an explosive process and resulted in more edges than MDP. As a result it would break down faster (and produce more fresh edges) than pdp.
I see why on the 100,000 polish it cuts faster.
and on a synthetic wheel where you are not embedding it into the surface it make since.
But on a Batt or a zinc lap, where you are embedding the diamond, would the mdp last longer since it would not break down as fast? Or does the fact that it does break down mean that it exposes new cutting edges, and this becomes the overriding factor?
