cutting a circle in marble

hi guys,

can somebody give me some tips on how to cut out a perfect circle out of a marble tile and a porcelain tile for a waste pipe.

we are tiling an ensuite in marble wall tiles 300mm x 300mm and there is a waste pipe that i have to fit a tile over. the pipe is the waste for the toilet. also we have the same scenario in the bathroom but the tiles are porcelain and 600mm x 330mm , i think?

so, how would i cut the hole out of the tiles without splitting the tile in half. :huh2:

hope somebody can help

I use a Montolit cutting set. Fabulous piece of kit but like everything else of quality it costs around £280 for the set. There is also a company on here called 356 Drills I don't know if they have anything that can handle it because I don't know the range.

Hi Sara..

You can buy a drill bit from 365 drills that will cope with that size hole.....here's a couple of pics....







Or you can mark the holes size and then plunge cut from the back of the tile and make a few cuts and nibble the shape out.....but for about £60 i would go for the 365 hole cutter then you can use it again....


you can order one here.....

Got to agree with previous posts, 365 Drills supply a 120mm core drill for this very purpose, I cut 2 smaller holes (40mm) in granite last week in about 5 mins total. Will go through marble no problem.

are there any other alternatives. ie one where i dont have to spend money hee
we have a small diamond cutter so i was thinking of cutting out a triangle after marking a circle and then cutting lots of small segments on the strips that are left but will nippers snap off small segments of marble and porcelain.

i thought there would be some old expert out there who would give me some of his wisdom and expertise.

As i mentioned Sara.. you can do plunge cuts on your wet cutter and cut the hole out in small bits at a time or maybe even use a grinder and finish off with some nibblers.....

After 10 or 15 mins of nipping away at porcelain, you may wish you had bought the drill.

No probs... ..............women spending money...they don't do that do they....

................let us know how you get around it then and maybe a pic or 2 eh.!!!!

Mark your tile with the circle then plunge cut on your wet cutter, moving tile up and down plunge cutting it in different areas but not going past the marked area. Then when large chunks of tile have fallen out nibble at the remaining bits with either parrott nips or larger nips up to the marked circled line.
