They have some quite interesting stuff on the 7th of this month.

Diamond core drill with bits and pieces for 29.99

But they don't tell you the sizes of the core drills in the set. IIRC
the last time the largest wasn't big enough by a mm or three to take
a standard 110mm waste pipe...

And for those of us who live in real houses with real walls:

Heavy-duty Masonry Drill Bit Set £9. 99
1000mm 12, 16 & 24mm SDS
or
600mm 10, 12, 16 & 25mm SDS
