Designing Kitchens and Bathrooms - drill hole in granite

hi All
I bought a granite slab 1 in thick
i need to cut it down to 24 in wide and drill 2 holes in it
1. i bought a diamond blade for my power saw
2. also bought a set of diamond hole saw

1. can i cut the slab with my power saw with this diamond blade and water the slab as i go along
should i de 1/8 deep cut each time

2. for drilling hole i want to used my electric drill at a low speed and not to much pressure with lots of water to lub it

is that a good way of going at it or is ther a website on how to

thanks

You can cut it with a circular saw and diamond blade, but be careful. First be sure the saw has enough power so you can cut through in one pass. Use a straight edge clamped to the top to guide the saw so it doesn't wander and miss the line. Be sure the saw is plugged into a GFI circuit so you don't get zapped. This is best done outside or in a garage so water spraying isn't a problem. Cut slowly while directing water from a hose to the blade so it doesn't overheat and you should be fine. For drilling the holes I assume the hole saws you mentioned are core bits without a center guide. You can drill a hole in a piece of wood slightly bigger than what you're drilling in the top to act as a guide. Clamp it to the top over the spot you're drilling, fill it with water, then start drilling. Pull it out every few seconds to refill the hole with water as it will be expelled by the drill turning. Keep it flushed out as sludge from drilling. Once you're started you won't need the guide anymore, so you can remove it. Be sure to pull out and run water in the hole frequently to keep it wet. Tools meant for this have a center feed water system which keeps it flushed out. Higher speed works better than slow, but don't let it jam because it'll twist your wrist like a pretzel. A 4" grinder with a clutch (Metabo) is safest, & core bits fit the 5/8" shaft which is standard. Good luck & be careful.
