I have been asked to lay a floor with 600mm porcelain tiles and wondered :-
1. What is the best method to cut these.
2. Is is safe to use an angle grinder with a diamond blade.

HI Captmjw

Have you tryed to score and snap them ? I am doing some 12mm porcelian tiles this week my Rubi would not touch them so I just scored them and went back to the old method of puting something under the score line and jumping on them . they broke no problem . You could use a wet cutter that will do it or a good blade in your grinder will be up to the job might take you a while that way . Hope this helps Steve

A proper manual tile cutter will handle almost all porcelain with ease. I recommend Montolit or Sigma.

It's safe to use an angle grinder with a diamond blade, if you've got safety goggles, hearing protection, dust mask, and steady hands. They're normally only used for intricate cuts through, not regular ripping.

what manual cutter have you got? a tx700n is what i use, last year I did some particularly hard V&B tiles, but with a 22mm wheel from tradetiler did the job no bother. If you are going to use angle grinder get a good quality blade (diamond continuous rim), they last longer and do a neater cut

If you use an angle grinder cut outside

If its a FULL PROJECT you have in mind to use an angle grinder then I would consider a dedicated tile cutter instead... Also be extra careful with using an angle grinder. They KICK LIKE MULES, are difficult to control and with no water feed things get hot quickly.

In contrast most dedicated tile cutters have a water feed to cool the blade and help cut down on dust. Angle grinders have no such system. They seem to have two settings. Off | And Violent.



If you must use a grinder go for a small one with a 110 blade not a 230 blade and make sure you wear safety googles. These are angry machines so dont expect any mercy.

You are better off with a cheap wet cutter fitted with a good diamond blade:



These are about £40 quid but they do have a wet cutter and give you control.


This outside scene is showing the mess tiling can make with a mixer for dry power ahesive plus the two types of cutters. An overarm radial cutter. Plus a small fixed blade table cutter.

I would consider the small fixed cutter.

I have a TS-50, a radial cutter which is too small and a flat bed wet wheel cutter. With the tiles being 600mm they are quite hard to handle.

Thanx for your detailed reply.
