Cutting porcelain tiles diagonally - Tile Advice

[StuVin]

Hi, I am trying to cut 600 x 600 porcelain tiles diagonally corner to corner on my bridge saw. Upon making contact with the tile, the edge chips leaving an unsharp cut at the start. Do you have any suggestions to avoid this. Could it be a sign that the blade has lost its edge? Cutting across a tile 90 degree to the blade leaves a clean cut throughout.
Kind regards,
Stuart

I should add they are a 20mm thick outdoor porcelain tile

try doing it in 3 or 4 passes and may help to cut right through tile each end first.

 

[StuVin]

Thanks Julian, I was thinking of trying a few passes as you have suggested. Would you suggest 5mm depth at a time, or would you make the first pass only a couple of mm.
Maybe it’s just trial and errror.
Kind regards

yes , about 5 mm then with grinder cut right though the tile at both ends then wet cut the rest in a few passes.

Thanks Julian, that all makes sense so I’ll give that a go.
Kind regards

It worked well today, so thank you
The cuts are on show so I wanted to get them good.
If I wanted to put a chamfer on them like the rest of the tile edge, how would suggest I go about it?

Angle grinder and some polishing pads

A chamfer can be created with diamond hand pads, an electroplated diamond vanity blade (on a variable speed grinder) or coarse polishing pads and a polisher/variable speed angle grinder.

Hand pad = slowest but most control
Vanity Blade = This is what masons use to chamfer granite worktops mostly.
Polishing pads = An alternative to an EP vanity blade.

Thank you ATS, I only have three tile edges to do so I may look at using a hand pad. Are you able to provide a product name and part number?

Thank you guys, you’ve been very helpful. Is there one grade of hand pad that will do the trick to create the chamfer or will I require multiple grades?
Kind regards
