Topic tags/keywords: granite

Hi everyone.
I have come across a few granite scraps that I want to incorporate into some wood working projects. Most of the larger pieces are jagged broken slab pieces 1.5” thick. I am trying to figure how to cut them. I was going to use a cir saw with a stone cutting blade. But will it cut something that thick. I have access to a grinder. However I have doubts that I could cut straight line with it. Any advice would be appreciated it regards to cutting, edge shaping, and polishing is appreciated. I have seen some some of the vids on youtube. Some were helpful some not. Thanks.

You need diamond tools to cut granite.

Rent a saw similar to this one with a 10” diamond blade.

use a daimond blade, make multible shallow cuts no more than a 1/4” at a time. try to keep the stone and the blade wet, if ya need to try to get someone to help you by keeping a steady stream of ware flowing over the stone while you make the cuts.

by the way dud I’m right done the street.

You will need a respirator to cut granite or other stone dry. Lots of silica dust. A wet diamond blade saw is the best way. I have a few different types of diamond saws. I also use a wet grinder/polisher for profiling and polishing the edges.

You can also check with a local granite countertop shop and see what they would charge to cut the slabs. Might be less expensive and give you better results.

I just cut a slab for the desk that I built. See my profile. I was able to cut it with a circular saw and diamond blade taking very light passes and a straight edge guide. If you try to cut too much at once the blade will deflect and the cut will not be square.

Have your say...
