I've seen this done, by starting the hole at an angle, the edge of the bit, then straightening up.Andyp wrote:I will need to drill 10mm holes through tiles and concrete. I have always used the pointy type such as this for drilling wall tiles

But I now see there are flat diamond tipped bits for doing the same like this

Are they worth the extra cost? They must be a bugger to to use without a jig to hold them still.

Certainly on anything like ceramic, marble, travertine then those diamond drill bits are the dogs danglies. You still need to start the hole at an angle or you can buy kits that have a V-section, a sucker pad and a small pressurised bottle of water to keep the bit lubricated. I've got one and again think they are the DD's.
Or a simple appropriately sized V-shape in some MDF/whatever that is clamped to your tile.
Forget using them with concrete ....SDS drill is all you need.
Only downside of the diamond bits is that they can be fiddly to remove the core after or during the cut.

IIRC correctly they are frosrproof porcelain. No worries about the concrete, that is the easy bit I am just a bit scared of cracking a tile while drilling. I am even thinking of drilling a 12 mm hole in the tile to leave plenty of room for the 10mm sds through the concrete.

I wonder if the suction pad will wotk on the non slip surface of our tiles?

I read something similar. How does one the fix the piece of wood though?

That wasn’t mentioned but some double sided tape should do the trick?

Have you got a good hammer drill for the concrete ? I remember once when renovating a flat in London I needed to drill some holes into the concrete walls. Tried my battery Makita hammer drill and the wall just sniggered. Got out my mains larger hammer drill and tried again. This time the wall could hardly contain its mirth.
So I went out and bought a large SDS combined hammer only, hammer+ drill, drill ..that sorted it. Only drawback was it didn't have a reverse so when I later got a wood bit stuck in some old oak, there was much swearing and cussing trying to get it out.
Good luck.

I have some that is at least 12 years old. Probably past it's best. Will search for the .fr equivalent.
