I have to tile two reception rooms in the same porcelain tile. These reception rooms are divided by a double door. One of the doors has a latch/lever handle and the other has a receptacle rebated into it to accept the latch.

In order to stop the doors from being pushed open without using the handle, I have to fit flush bolts to the top and bottom of the door that has the receiving receptacle rebated into it.

This is not a problem wih the upper flush bolt as it will go directly into the door frame. However, the lower one will go directly into the tiled floor.

I have had a look at flush bolts and the shoot plate - ie, the receptacle that receives the bolt - is rectangular in every case.

I could just drill a hole in the tile to receive the bolt but that would not look very good and I am looking for a beter solution.

If I could find a flush bolt with a circular shoot plate, I could lay the tile, drill a hole through it, backfill the hole with some concrete/mortar and then screw in the shoot plate and that would work. But I can't find a circular shoot plate.

I imagine that if I tried to rout out the space for the shoot plate from the tile, that would break the tile. I have seen some Dewalt carbide tipped jigsaw blades but the shop said they wouldn't do the job on porcelain. Another shop said they might work but I would get through a heck of a lot of them. At GBP7.99, I don't want to buy twenty sets, take them overseas and then find they don't do the job.

So has any one got any suggestions that are better than simply drilling a hole in the tiled floor to receive the bolt?

Thanks.

fix the receiver for the shoot bolt into the floor in the correct position

then start the tiling at the face of the double doors were the shoot bolt goes into the floor so you could cut a small square out of the edge of the tile along this at the bottom of the doors and then continue as normal with the tiling

before you start laying you could also gage the tiles so you don't have any small cuts to the side walls of each room

Stitch drill a load of smaller holes in a square. Then nip the edges and file the them smooth.

That could work nicely...

That would work too, I think. Thanks.

Last time I did it in these big 900x900x12mm Â£80 a pop tiles haha stitch drilled 3 7mm holes with diamond core then used diamond file on a dremel to square off the hole.
