Porcelain Tiles - Bosch GTR 30CE

I'm considering buying a Bosch GTR 30CE Pro Tiler kit and, as this is a "dry" system, was wondering how long the cores actually last. I could buy some cheap bits, drill a few holes, and then replace them, but I also need a router bit for profiling tiles.

Is the Bosch GTR a good investment or could I do the same job far more cost effectively ?

Thanks in advance for any advice.

Not sure but I reckon that cheap bits won't last on porcelain - it's such a hard material and usually has to be water cooled

Not seen that before but just watched a video on youtube.



It looks like they have adapted a rotozip to be able to hold diamond coated hole saws like they sell at Richon- richon-tools-t20002.html

After watching the video with the diamond milling tool it looked very hard work, I’d love to see that work on hard porcelain. The guy in the video looks like he is struggling with it !

It’s not something I’d ever consider buying but I can’t wait to hear some real reviews on it ;-)

I once tried a Rotozip, it was useless on hard tiles and the only thing it could cut was plasterboard. I sold it on ebay :lol:

We use a few commercial tilers and the fact that none of them use anything like that, speaks volumes.

They are the same as me, suitable size diamond hole saw in a drill. Depending on the size of the hole, angle grinder.

Thanks for all the excellent advice.

I'll save my money and spend it more wisely on something that will do the job properly.

Just notice you said profiling..........you mean you want to put an edge on them. Mitre?

No, its more for cutting around door architraves and that sort of thing. I guess I could just cut the bottom of the architrave off instead !

toys for show, grinder for dough! I use my grinder for profiling, pretty easy and quick when you get the hang of it. I would definitely trim the architraves and slide the tile under, save your money on the bosch thing and buy a fein for trimming archs

Thanks for the info haveagohero.

Based on the excellent advice received on this thread I've definitely decided against the Bosch. Are your grinder and Fein the 240v or cordless versions ? I much prefer cordless but their so damn expensive !

Corldess are pretty gutless when it comes to tiling, ok for thin ceramic but will struggle with the porcelain. You need mains powered, ideally 110v but if you are diy then 240v will be fine.

That's good to know, thank you. I never work on site so will go for 240v.

If you are in your own home then 240v is fine.

110v is for site and domestic. No excuse for a sole trader/company taking 240v tools into a domestic property.
