ceramic sink?

[Mike Jackson]

I normally use a nail punch.

Here's another little "How to" video that we did at the same time.

The basic concept is that you have a unit with a hole pre-drilled and that you want to enlarge.

Its a bit like if you have a bigger size tap to fit on a sink. The hole is already there you just need a bigger one but in the same place.

What can you do if you want a bigger hole drilled into a ceramic sink in the same location as the existing hole.

Something useful is that the yellow guide plate will flex and bend to the shape of the material being drilled. Its not rigid.

Ceramic sinks and toilets etc are a pain for being rounded and smooth (and slippery) so difficult to clamp and sit still.

Hopefully these videos will help some!

Note all ALL stages of drilling SAFETY SOCKS were worn (steel toe capped socks) to comply with health and safety...

they just tap out with a little chisel or just tap with a little tack hammer always from the top ie face side
