| Drilling 5/8" hole in granite I need to drill a 5/8" hole in a very expensive piece of granite counter-top. Should I drill a smaller, say 1/4", hole first?
Any drill bit recommendations or techniques would be appreciated. |

1 edit | Yes, I watched some of the top videos from Google but they show larger holes around 1" plus using a hollow hole drill bit. I'm thinking for 5/8" I should use a solid bit. That's what the directions that came with the faucet say to do. |

I don't see that either of the big box hardware stores carry 5/8" diamond core drills. |

Any chance the piece can be carried to a professional shop where they have the equipment?

| No, it is 12 ft long and completely installed. Removing and moving it would be even more risky. |

I would be VERY afraid a solid bit would severely chip the edges of the 5/8" hole and possibly crack out a large piece.
Since you say material is expensive, and there do not seem to be any "hole saw" style diamond drills around, would it be worth it to get a pro in to pop the hole?

I like DIY also. Some times we need to realize the risk/reward just is not there to go the DIY route.
You could have someone pop the hole, (and tell your self you had purchased the top with the hold already there, (:>)), and you could do the finish work.
If you could find a 5/8" core drill, then it would be a new ball game, right?

You should be able to buy the proper coring bit from one of the granite places in your area or you can order one from Amazon. This is pretty cheap for this type of bit but it should drill a few holes.

While it's not granite, I used something just like this to drill the holes in my master bathroom floor.

Thought I bought it off the shelf at Home Depot but can't remember.
Here are a few pics of how the holes looked:

The nice thing about the one I showed is the water cup kept the blade from overheating.

You might try calling a tool rental place. They may have the bits for their tools they rent out.. |

If a professional did the same damage, he/she has insurance (or would pay out of pocket to avoid the claim). |

My philosophy is that If the reward is worth a risk I can afford, and I am confident of my abilities, DIY. If not, pay somebody to do it who has the skill and will assume the risk.
Personally, I'd be afraid of overheating and cracking the material, or having the bit walk on me and be off center.
If it were mine, I'd also look for a solution that doesn't involve drilling holes in the granite.

I'm going to question this. I can't imagine anyone guaranteeing a 12' long granite slab they did not install when hired to drill a few small holes. If they do take the risk then I would expect those to be very expensive holes! |
