We use a tile drill bit for these, its much safer to use than a masonry bit.
Just get one the right size to start with and don’t hit the centre punch too hard.
Like most kitchen sinks, you need to cut a hole for them, we use sealant to hold them in place.
You first use your sealant on the underside to the sink, then when it’s cured a bit, go round the top rim edge of the sink.
The sink shouldn’t move once the waste and water pipes are in place.
