I use a marcrist 28mm core drill no breakout then usually sleeve 15 mm water pipe with a bit of overflow quick seal with brown lma job done

Makes sense really. If you use one of those kits from the sheds there's be no need to isolate and drain down in the winter. Just put it back in the warm through the 110mm hole. Could save the householder a fortune in burst pipe repairs.

Thinking about it, I'm lucky to see a gas pipe sleeved through a wall, let alone an outside tap...

If you can gain access to Makro, these drills are £10.89+vat. They are also available in 450mm for £7.49+vat.
They might struggle on solid concrete but for normal household bricks and blocks, they have never let me down.
