A good idea, and I could do it if I used a short adapter/extension lead with a Shuko plug and a couple of BS1363 sockets for the wallwarts. I may not, because really only the UPS is going to suffer with a large overload, and the sockets won't even be live after I'm dead and gone and the UPS disconnected.
That was my reasoning, but I will see if 1.5mm will fit. Glad to see you agree!
Mine's just a cheap Titan from Screwfix.
Hmm. I have a corded DeWalt SDS. Does a job but the clutch slips:-(
One tip that can help, is that once the core is started, take the pilot bit out of the end of the core - quite often drilling the pilot with no hammer action in hard material is very slow.
(I normally stick a pilot hole through with a 10mm SDS bit first to check the exit point. Then use that to run the core pilot for getting the core started. Then take the pilot out once going (otherwise it can vibrate loose since it is not actually pushing against anything)
SDS clutches are not usually set at a level that is ideal for larger core bits. In an "easy" wall they are usually fine, but it a hard / damp one, just spinning the core at all can be difficult IME.
(TBH, my dedicated core drill is not much better - I but I think that is a fault of the drill!)
Some Core drill sets come with a guide rod which enables you to drill a pilot hole straight though with a normal SDS drill. The guide rod then helps guide the core drill along the pilot hole. This is useful if you want to core drill from both sides and align the holes.
