Pictures as promised.

Firstly, this is what happens if you use it on a grinder or at full speed on a polisher on Porcelain. So you can see, I can't recommend high speed use for this reason.

Same porcelain tile - but using the cutter at 2000 rpm dry:-

Marble and quartz was just lovely to cut, smooth and easy. This is a piece of 10mm Rosa Aurora (AKA Estremoz) from Portugal.

This was dry and slowish, around 3000rpm, but you just didn't need to be any faster. It cut quick enough and was quite controlable.

However, this was a smaller washer that simply wouldn't work on Porcelain, so the next size up cuts slightly shorter than this by 0.5mm. Not a great deal - but it meant it worked on stone and Porcelain. As what we're looking for here is a one size fits all solution we have to go with the Porcelain Specification.

It will still work beautifully on all stone though.

Granite, the only bit I had knocking around was 10mm Blue Pearl sample, which wouldn't be my first choice for mitering dry! But it's certainly a good test.

I struggled to photograph this but these are the best two images I got.

This is the one time I would recommend wet cutting. A granite of this nature with such a coarse grain really benefits from the extra lubrication and cooling it's given with water. On a tight grain like Absolute black I think this would be less of an issue.

I bet the wet results would be even better

On to a winner there Alan!

Alan. what thicknesses will this do. I think you will get great results with travertine.

I think so too, I have a feeling it would speed the process up also. Particularly with porcelain.

I made this at 12mm with travertine in mind, so it should be good up to that thickness. However the quality of mitre on travertine is more likely to be determined by the amount and quality of filler that is contained within the stone.

On travertine I prefer a 10mm half bullnose finish, I think it's just more suitable for the material type.

A good quality trav will be close in texture and density to marble, and I got the best results from my tests with marble, which is relatively soft.
