Hi Brunog,
Steve could you ask your brother a source for drills for granite?
Thanks
Larry

Here is a link to one site that has em...
http://www.diamond-drill-bit-and-too...Drill/MAIN.htm

They use the core drills as most of their holes are relativly large. The same site has some tips on using them, as well as other diamond tooling. His shop has a nice CNC machine that does the edges and the cutouts in the countertops. Fancy edging tools like these..

Some of the profiling tool bits they use are > $600 ! They last quite a while as long as they keep em wet, real wet :drowning:

I've used the diamond core bits to drill through glass. Just keep the feed rate real slow, keep em wet, and back em out frequently to cool and flood with water and they work great. On heavy granite once you are deep enough for your insert or whatever, just do what the Egyptians did, snap the center post out. http://www.geocities.com/unforbidden...ng_drills.html
Just use lots of EG (elbow grease)
