Will a skill saw with a diamond blade cut through granite? I kept the kitchen sink cutout from my granite counter tops and would like to use it to piece together a surround for a sink I’m installing in my shed.

A diamond blade in a right angle grinder is what you need to use. Unless you don’t have one, then the circ will do. Tape your line with masking tape and cut the edge so you don’t loose the line. It will be VERY dusty, so if you have an assistant, have them hold a shop vac against the cut to help keep down the dust storm.

So tape it with blue painters tape, and about 1/4 inch at a time is ok?

I’m also assuming I can get a two part epoxy to connect the seams.

Hey sweets
I’ve cut granite with the composite blades made for concrete just as David describes.

That’s exactly what I’m gonna use Jim. I’ve already got one from a project last year where I scored and then stained an outdoor concrete patio. The granite is taking up space in a corner of my shed so I figured I’d use it vs buying a prefab formica countertop or formica and attempting to laminate it. The contertop including the sink insert is only going to be about 27 in x 27 in.

This will be my first attempt at a cabinet; we’ll see how it goes.

I ve seen people run water over the blade while cutting to save the blade and avoid dust kinda like a wet saw

Gentlemen, a 7” dry cutting diamond blade (for stone…NOT concrete) is the preferred choice in the world of granite. Priced anywhere from $39.00 to $89.00 depending on quality (diamond concentration, quality of plate steel etc) Cut slow and let the diamond break down. DO NOT use elbow grease in cutting as this is not a sheet of plywood! Like Adam said, a spray bottle of water will help make the diamond blade last longer but these are DRY CUT diamond blades so the only reason water is used is to keep the dust down. Remember, there probably is no GFI on the saw so lets not get crazy with the water. Don’t need ay fried Lumber Jocks!.

General 2 part epoxy will not do the trick. Acrylic or polysester knifegrade is the ticket (Bondo for stone) Acrylic knifegrade is generally only used in stone lamination.

We are an Alpha distributor and while they are a good tool, their pricing is higher than you’ll need to spend for a one cut job.

Sweets, look for a granite supply type of company in your area and buy a quart (usually the smallest size) of polyester knifegrade to do the seems and it will run ya around 16 bucks. A 2oz. color tint for the seem if needed around 3-4 bucks.

Dave,

Thanks for the tips. I’ll let you know how it comes out. I’m probably a few weeks away from starting; I have three kids all under 2 and a half and they keep me very busy.

Just an update. I put the diamond blade in a table saw and it cut the granite without any trouble. I did as most of you recommended and did it in a couple of passes. It was a little dusty, but not as dusty as I thought it would be. I cut it outside, so no real issue. For future reference, cut it with the surface/face to be exposed down because it chipped slightly as the blade exited on the final pass.

Thanks for all of your help.
