I figure some of you probably do kitchens... And thus granite counter tops... So... Anyone have a reliable chart or numbers for drilling granite?
1.25" diameter hole, 7/8" material thickness.
Looking for HP, thrust (low?) and RPM of course... Much coolant to be used I assume.
I suppose it all depends on the tooling, but lets assume an inexpensive, standard diamond tool.
