Ok, do a mitred cut right through the middle of a full tile and see if it has cut straight.

that shouldn't run off, but that's not how you would normally mitre a porcelain tile.

Ok so I have sharpened the blade as suggested by Dave ,cut and measured numerous tiles and have got the saw to a place where its pretty much cutting on line....however tilt the saw to mitre and the cut runs off.

I have attached a pic of a mitre cut on a 200mm off cut of tile to show you what Iam trying to describe.

how did you do the straight cut? Wet saw or cutter. If its a tile cutter you won't make a nice mitre.

I did a straight cut with the wet saw before the mitre. If I mitre through the middle of a tile it cuts straight but leaves a messy edge that would be noticeable.

So it only seems to be struggling when I mitre along the edge of a tile trying to leave that 1mm to ensure a clean leading edge.

its chipping a lot for a straight wet cut.

yes but but you can then just remove the messy edge with a straight cut along the mitre about the width of the wheel. If your trying to remove the back edge along a straight cut then naturally the blade will want to kick away from the tile. Try progressive passes going deeper each time so their are not too much pressure on the blade.

I'll try that and get back to you. Cheers.

Sorted, the answer was to buy a new blade. Picked up a porcelain blade this morning and Im now getting good straight cuts and mitres are neat and tidy. Minimal chipping and running true through the saw.

Maybe just the stock blade wasn't up to the strength of today's porcelain tile.

Thanks all for you help.

Nice one, what blade did you get?

 

[DavieA]

I got one of my mates to pick up an inverted A ultra thin blade from Diatech. Hadnt heard much about them but its looking good.

 

[charlie1]

What diameter? How much? I use the inverted A on my grinders

 

[DavieA]

Went for the 250/25 for £90 ex VAT but they also do,

105/22
115/22
125/22

Id consider one for my grinder, it be handy for sockets etc if only a bit smaller.

Take it you get on well with the inverted A on the grinders?

 

[charlie1]

Yes, I have 4 grinders, 2 are fitted with inverted a, one has cupped wheel and one has Marckist 850, pretty good blades and reasonable price. I did ruin one by cutting metal trim with it, need to re expose the diamonds in it. How much was blade?

 

[DavieA]

£90 ex VAT, reasonable IMHO.
