Change your thread title. Try to be a bit more informative with your titles, as "Advice needed" could apply to every single thread on the forum, so people don't know what your thread is about before visiting it. If you put "grinder with chipping tiles" in it, somebody who's had the same issue will quickly spot it and perhaps respond.

Segmented, or continuous rim blade?

 

[Andy Allen]

Are these the cheapy johnsons tiles from the diy sheds?

I bought a marcrist ck 850,they are Johnson's tones tiles yeah look cheap

 

[Andy Allen]

I had that blade in my cutter......seemed to chip tiles aswell especially the cheap crap ones...

I find the blades i use for cutting most decent tiles tend to chip the really crap tiles must be the thin glaze on them..
Got round it once by borrowing a customers cheap crap wet cutter....cut them a treat!!!
Moral of the story...cut crap tiles with a crap cutter....😵

When getting a new blade run it through some travertine ,seem to bed it a bit ,with it being natural stone

Scribe your L-cuts and then cut into the corner of the scribed lines a couple inches or so away from the scribe , then Break both pieces out with your dry cutter.

Nice clean edges then.

Try holding a damp sponge against the blade while cutting it to keep it cool. I do it quite a bit if I can't be bothered setting my wet saw up.
Be careful what though.

I've heard ck850's are very good but I really didn't get along with mine, chipped loads. If I was trying to do a particularly thin L cut (20x10 around a socket) then I had no chance at all, vibration just broke the tile. Maybe I had a bad one.

Try ATS diamond blades. A quarter of the price and better. I have been buying ck850's for years but no more they've gone crap, try the turbo blade from ATS.
turn the grinder on and off quick and check the blade as I slows down it may have a kink in it as mine did the other week, instead of a 2mm cut thickness it was doing about 4mm

I just recently got an ats turbo pal, again not the best blade I've used but like you say, a fraction of the price and a lot better than the 850, pro gres for me next tho

 

[py rookie]

Yeah I think the blade is not the best,it as soon as it touches the tiles the paint just rips off hence chipping,doesn't help with the tiles are black and grey

 

[Concrete guy]

Use a continuous rim blade for tiles like this, the turbo design by it's very nature will cause chipping on some delicate or lower quality products.

Continuous rim blades are cleaner/smoother in action but don't cut as fast.

 

[Old Mod]

Yep def with Alan ^^^ turbo blades are too aggressive with ceramics by far!
Need continuous rim like a J slot!
Other suggestions will work too mind.

 

[AliGage]

If you want a marcrist blade fir ceramics use the 650.
The 850 is fir porcelain and harder materials.

 

[py rookie]

Just bought Rubi csv 115 should do the trick

 

[Unused Account 1]

Just buy a cheap blade for ceramics ,and keep the good ones for porcelain or stone ,

 

[py rookie]

Thanks guys continuous blade did the trick but when blade touches tiles the blade sparks if that makes sense,why is this

 

[kevsalt]

try a black diamond pc blade ..ace blade and not expensive ..thats all i use now ..only exception the squadro for leccy boxes..beast

Grind about 5mm from the finished edge and then nip the rest , perfecto
