I would question drilling an expensive granite countertop rather than placing the umbrella at the front or back edge, but that is your business.

You want an experienced countertop installer. If he knows what he is doing he should place a timber support directly under the hole while he drills so there is no downward pressure on the hole as it is drilled or from the weight of the drill (wil usually be stand-mounted), which reduces the chance of cracking to almost nothing. He should use a diamond core drill to drill the hole, and bevel the edges top and bottom to reduce cracking risk.

When you call him, give him the pole outside diameter and ask if he can provide a plastic stress relief sleeve - fits in the hole around the pole and prevents the pole from staining the granite or rattling in the wind. He will then drill the hole to fit the sleeve.

Make sure the pole is VERY firmly planted and bolted or screwed into a socket at ground level, so it cannot lift up or tilt in the hole and possibly crack the countertop, and of course the countertop should be firmly fastened to the cabinets or base so a strong wind on the umbrella cannot move the countertop.
