In my opinion gently does it with a ball peen not all knock outs have a thin glaze and if you are going to do the combination basins which give you a choice of 1 or two either side a big bash can take the lot out...saw this once at the initial re furb of the Theatre Royal in Bath in 1982 ish ...not moi that guy was mortified ..Why a dislike Rob?? I’m not wrong?
quite right some of these designer ones are worth a fortune esp the Italian onesDid a howdens one last week, drilled it with a diamond tipped 6mm bit from underneath a few times first...
yes I am a scaredy-cat
I use hole saw with thin ply templateI fitted my first white ceramic sink the other day or it may have been porcelain and it required me to use a 10mm centre punch and chip my way through for tap hole, the hole came out jagged and not in one round piece like the knockout.
I didn't fancy drilling it as if the cutter slipped when bitting in I would have have to buy a new sink (£180). And drilling from the underside may have caused breakout.
Just didn't seem right as I had to really whack it hard to get through.
Not sure I'll be doing another, has anyone ever cracked one?
