Cutting small square hole

[burncross]

hi, whats the best way to cut a small square (50mmx50mm) in the middle of a porcelain floor tile?
bit too small for an angle grinder or plunge cut with a wet cutter.

Transfer your markings to the underside and cut it from there with your grinder

Yep, same for me. Good quality porcelain blade and cut from the back.

you could core a hole and rotozip it out as well

I use my makita 12v wet cutter, I can cut 90% of it from the face side, and turn it over to finish off. No overheating either if your close to the edge:smilewinkgrin:

If you want to go in

FROM THE FRONT

1. Mark it out

2. Start to drill the tile with a diamond core drill bit

3. Use the diamond core tile drill to put a hole all the way through to the back of your tile.

4. Water cut or wetsaw etc to cut the gaps out between the holes

5. Drilling four holes from the FRONT of the porcelain tile guarantees that:
a) You are 100% sure where the hole / socket will end up !
b) Will drill a chip free hole out of the tile - (No blow out)
c) Can visually see the blade as it cuts the straight lines (you can look through the holes)
d) The edge of the blade will definatly stop short rather than run on into the tile.

This is shown on a soft ceramic but the example works on a porcelain.

I have a small wet cutter i use with teh guard off, push the tile down onto the blade until it comes through the face. Can cut really small holes and is the same principle as using the girnder on the back but this way you can see where you are cutting
