My dad went on his own and picked up a bunch of various scrap table top granite. I havent gotten a chance to go through it yet. One big chunk looks like it has labdorite mixed in it. Is the more exotic tabletop granite composite material? Now can tabletop granite even be cabbed?

If it looks like Labradorite it is probably Larvikite from Norway and I use it for knife scales frequently and jewelry too.  It is also know as Blue Pearl Granite but it is not a granite....

So it is a usable material and wont tear my wheels up then?

It is very easy to work and fairly soft.  It does have some naturally occurring "texture" to it so I usually sand to 600 grit and use Hxtal to fill the pits, vugs, lines and any other natural structures.  I just am extremely picky about the final polish I obtain.  If you don't mind texture showing and do not use any sort of filling natural occurring structures a bit the stone is strong and won't crumble. 

I do note in my sale listings that I do fill in natural occurring structures to get the best polish possible for the stone. 

This really is not required unless it is for stones in which there is a significant change in value for "treated" stone such as Turquoise, Emeralds, Rubies, ect.  This filling of natural occurring stone structures for improved polish is controversial on this site but I have all of the requirements on file if anyone wishes to once again argue.
