I'm looking to add an extra hole to the kitchen sink area of my granite countertop. I called a company for the job, and they quoted me over $300 just for one hole! I found a diamond drill bit for around $45, and after watching some tutorial videos, it seems straightforward enough. However, I'm wondering if I'm crazy to attempt this myself or if I should just pay the pros.

It's totally doable, but just make sure you measure everything carefully before you start! Use a little plumber's putty to create a dam around the spot where you'll cut, then add some water to keep your drill bit cool. Start slowly, and once you have a groove, you can speed up a bit. Just remember, keeping the tool cool is key since those bits can be pricey!
If you're feeling confident, go for it! Just remember, technique is super important. Use lots of water to cool the bit, and don't rush it. If you have doubts, definitely consider hiring a pro; you don't want to ruin your countertop!
True, but if the company messes it up, they handle the costs, right? I’m stuck on whether to save the money or trust an expert.
Man, if you mess this up, fixing it could get way pricey! I'd recommend practicing on something less critical first, like a tile. If you feel uncomfortable going for it, maybe just hire someone. It's about peace of mind too!
That’s a great point. I didn’t think about the potential costs if it goes wrong. Maybe I'll just fork over the cash to the pros.

You’ve got this! Just be super careful not to put too much pressure, or you could chip the back. Support it properly with a block of wood if you can.
