Angle grinder cutting on top of a board

[Italy]

I don't like cutting on a piece of wood,
I prefer to use the cantilever blade on a bucket
or a lot of adhesive, I have the impression that the blade
lose performance by cutting other materials.
but I'm just an apprentice

I've used the thigh method in the past. That ATS blade just went straight into my leg. It didn't hurt but I won't be doing it again.
I find that the customers lawn works best or if there is a grass verge outside their house. No vibration transferred to tile and less chance of breakage.

Used the thigh method 3 times now

I have offcuts of floor board I could use would that do?
Don't want to effect the blade but if it can cut porcelain then wouldn't think too much of going through a few mm of wood.

Blades today are very material specific, generally speaking you should use one blade for one material.
I’ve noticed in the past that if you use a blade to cut porcelain it’ll give a very clean cut.
Then on next job use it on a stone project, the blade will cut very well as it did on the porcelain.
Then go back to porcelain, and it’ll chip the hell out of the porcelain because cutting the atome has changed the properties of the blade.
In a perfect world, you’d purchase a new blade for every job, giving yourself the best possible outcome every time.
Applying that theory to cutting through a tile in to something as hard as a timber, you would run the risk of taking the edge off the blade.
But it’s better than nothing, and always be mindful of what’s underneath, like a finished floor or surface of some kind.
Someone working with me recently drilled straight thro a slab and in to a finished timber floor.
Cost £400 to replace that board!

Thick carpet or underlay on top of a Keter table does it for me.

I use tile offcuts under my tile to be cut

I've had a timber top on my table for a while but it's warped due to getting wet a few times. I'm gonna replace with 30mm XPS board this time.
