what's the received wisdom on best/easiest ways to drill small (6
or 8mm say) holes on porcelain (aka f###in 'ard)
tiles?

Any links to recommended products appreciated

The tiny diamond grit edged bars and hole saws seem to be one of the
best solutions. Certainly better than the solid carbide bits (which can
take 20 mins to do a hole and only have a life of a dozen holes or so)

I've used a couple of these (different sizes) and found them fine.

+1 for Erbauer diamond tile drill bit, but I don't know how you start a
hole with one of these as they are flat-ended.

I don't know if these will work:
http://www.screwfix.com/p/bosch-mult...5#BVRRWidgetID
But they go into things like reinforced concrete lintels and flinty
concrete like nothing else and knock spots off ordinary TC-tipped bits.

When I came across a porcelain tile for the first time I had no idea
what it was. I could barely make a mark with an ordinary masonry bit
(Tungsten Carbide tipped). I had a Dremel solid TC drill bit, and
despite using that previously to cut through 3mm stainless steel like
butter, it could barely penetrate the porcelain tile. After 10 minutes
the TC tip was rounded! The Erbauer diamond drill bit completed the job,
but it had to be done slowly and with minimum pressure.

you drill a hole in a bit of plastic or wood to make a template, with an
ordinary drill, and use that to start the core drill.

Or alternatively, just start very slowly and carefully with very little
pressure

it reduces the amount of hard material to be removed, and diamonds, that
you need.

I bought one to drill quartzite tiles. It was perfect.

No, I had a decent Armeg one with water spray. However they were thick

it reduces the amount of hard material to be removed, and diamonds, that
you need.

Indeed for larger sizes...

But say a 2mm core drill wall.
On a 6mm core drill that would leave a core of 2mm diameter? On
8mm holes a 4mm core...


Its nothing like 2mm wall, Its more like 0.5mm on a small drill

Doesn't seem hugely beneficial especially with presumably more
complicated manufacture & more diamonds to cut both sides of the
core's "slot" vs a few to put on the end of a solid diamond bit &
grind the lot out...

Its all on the end. Not really any on the sides



I bought one to drill quartzite tiles. It was perfect.


What size though?

6mm IIRC. It was for all the screws to hold the glass in place, and the
various shower 'furniture'

You might have got away with a TC-tipped masonry drill, as quartzite
tiles are not as hard as porcelain tiles.

My experience was similar. Hard porcelain is much harder to drill than
glass, for instance.

+1 for Erbauer diamond tile drill bit, but I don't know how you start a

After some experimentation, I break the glaze with an ordinary masonry
bit, then swap over to the diamond one, otherwise they skate about all
over the place, no matter how much masking tape you use!

The Bosch ones have a 'point'. Press gently until you hear/feel the glaze
go, then start drilling.

Same here. And the diamond 'core' type worked best - although still very
slow. Use a slow speed, plenty pressure and dip it in water frequently.

Unless you've tried drilling hard porcelain, you'd not understand.

I used the edge of the core type to break through the glaze, then moved to
right angles gradually. You do need a steady hand and a drill you can
support near the bit, though.

Put the bit in a wheel brace and gently 'rock' the bit, just a little, er,
bit. Because it's turning only well under 1 rotation it doesn't 'walk'
appreciably. This works well with ordinary bits and tile spades, but I've
not tried it with a cylinder.

All of the diamond bits on SF that I looked at have wide-ranging reviews.
Seems that a £20+ one can fail after 1 or 2 holes, so might as well get SF
or Erbauer.
Possibly too much force had been applied to some, instead of letting the bit
just grind through.
