So, I managed to score a large, albeit broken, piece of granite today. (See attached picture)
Which kind of works out for what I was wanting to do hence is my couple of questions.
Who, if anybody, knows anything about cutting and polishing granite?
What I’m actually wanting to do is cut one of the pieces down to 24x24 in and then cut the other chunks into smaller (possibly shaped) pieces.
Once cut, I would like to polish them as smooth as I can because they would ultimately be used for pastry or charcuterie boards.
I already know that Granite is not good for cutting boards or chopping blocks because Granite will f up a blade almost immediately.
That being said, the extent of my experience on this particular matter stops at knowing that I need a wet/dry Diamond marble and tile cutting blade.
So now I ask, does anyone have any experience in this?
Do we have a blade for this somewhere?
If not and I get a blade, can I use it with the table saw, track saw or bring my own?
Is there a bandsaw blade available anywhere for cutting marble, granite and tile?
So, I’ve done some stone carving. Mostly Marble. Marble because it is calcium based. If you inhale marble dust, your body can absorb it. But granite is silicon based. You body can not absorb it and it causes some nasty diseases.
Do a search for granite workers and lung diseases. https://www.compwestinsurance.com/resources/silica-hazards-in-granite-overview/
If you want a longer and more detailed explanation, I can give that.
Separate from the dust precautions, is that natural stone, or is that one of the resin bonded “quartz” countertops. Both by appearance, fracture appearance, and the labeling printed along the length, I’m thinking it is the resin bonded quartz product.
I have limited experience with granite, but hee goes…
If it’s granite, diamond blade in a skill saw will do it, but do use a guide.
Silestone cuts more quickly and easily than granite.
Both make tons of dust, so wear a good respirator.
Some shops use a hose running near the cut as a cutting fluid/dust reduction.
expect to get wet, and if yer doing it dry, without a shop vac, expect yer skill saw to inhale the abrasive dust and suffer an early demise.
Barring investing in a half mllion dollar cnc granite saw, or even a water cooled disc grinder, I’ve seen granite workers use the running hose thing for lubrication while using a normal angle grinder.
And yer gonna need diamond pads for it
Granquartz is a great source of info and diamond polishing pads are not that expensive
