   use a diamond bit and water on slow speed.  Make a template a template with plywood.  drill through the plywood and then set it over the location.  This will help with wander.  Take your time and do not overheat the bit.

   Appreciate the advice - have ordered my diamond bit!

   I need to drill 4 relatively small holes - 3/8"D x 1/2" deep to accommodate the underside sink clamps, so it shouldn't be too stressful.

   It depends on the size of the hole.   If you're drilling a 1 3/8" hole for a faucet, a diamond-tipped hole saw is faster than a drill -- you're removing less material.   If your slab is granite, not marble, the hole saw has a big edge over a drill.

   consider hiring a pro.  it is cheaper that way than if you screw it up.

    MArble is very soft. Cuts like butter but it has veins. I'd recommed that you put a piece of masking tape over the area youre going to drill. Can't hurt.

   In his first interview since the stroke, Ram Dass, 66, spoke with great difficulty about how his brush with death has changed his ideas about aging, and how the recent loss of two old friends, Timothy Leary and Allen Ginsberg, has convinced him that now, more than ever, is the time to ``Be Here Now.''

   Good luck with the drilling. 

   FYI, our stone fabricator here drills the holes for us.  We just supply them with the sink when we place the order.
