Tiling a shower former

[Stevies205]

Hi,

First post on the forum although I’ve been reading a fair few posts for a while.

I have a three shower areas to tile two of which have offset square drains and as such I need to make some tidy diagonal cuts.

Tiles are 450x450 but using a wet wheel seem prone to chipping. I’ve tried taping, going slower, turning over etc but nowhere near the finish I require. I’ve tried a number of cheap (£100 ish) wet table saws but with a good marcrist blade all with the same result.
Cordless angle grinder with a viper blade is a very nice cut but can’t cut straight enough to stop the back edge of the wheel chipping occasionally.
I’ve also tried a dry score (rubi ts) which achieved a good finish but obviously won’t create a gap between the two halves of the tile for a grout line. Should I be buying a bridge saw?
I’m happy to spend a bit of money on good tools but don’t want to buy something that won’t do the job.
Thanks

Cordless grinder, steady hand and a wet sponge on the back of the blade as you cut

You could try scoring the line too before cutting with your grinder.

The cleanest way I've found yet is to score a line using a Montolit STL blade in a grinder.
Clamp a straight edge and lightly use as a guide.
You will get zero chips using this blade and a few light passes rather than one deep pass.
Aim to cut down about 1mm, then switch to a normal blade (I like Marcrist akkumax ck850) to complete the cut.
