Ats porcelain blade issue

Concrete guy · Aug 22, 2018

We'll see what we can find at smaller diameter. Lots of blades exist at this size designed for stone it's finding one suitable and reliable for porcelain that's tough.

These blades are for cutting not for doing mitres. No wonder they break. Get a profiling disc instead.

Never had this happen before

I had a premtool do the same, about 6 weeks old

Your still cutting when your doing a mitre Tom.

But you can also do a mitre by grinding the tile too and it is easier to do it free hand than trying to cut a mitre. I bet Mike was using the blade like a grinder.

Like I said do a lot of mitres ( cutting ) and had two blades go not blaming the blades yes probably not designed for it but they do a fantastic job at it wouldn’t use anything else never got to grips with profile wheels except bullnose

Out of interest, how often do most people tend to change their blades, and if you use them wet or dry?

Any profiling discs you recommend? The montolit one is decent but a bit pricey

Tom is quite correct, they’re not designed for mitres, some even print a symbol on them to denote that.
Using these blades at an angle stresses the blade, they’re designed for straight cutting only.
The tendency from the user is to inadvertently push the blade up in to the material as well as forwards, this effectively bends the blade as it’s used.
Nearly everyone I know has suffered that kind of damage

Ats carry a very good profiling blade, that works with porcelain.

The STL blade you mention can be sourced from our sponsor @Pro Tiler Tools
Just be aware they are very material specific and are best used for profiling and not actually cutting as their literature suggests. But that’s in my opinion.
(And I have lots of them!

)

Rubi have also just brought out a half decent profiling blade also.
Can’t remember what it’s called but it’s quite distinct with its golden/bronze colour. It’s also smaller than most.

As with all profiling blades tho, you should first cut away the ‘meat’ of the tile before profiling, in an attempt to lengthen the life of the blade.
