Makro have a set of 160 assorted drill bits on offer at the moment for £19:99. JCB branded in a metal case, you get carbide tipped masonry drills, titanium coated HSS drills and spur point wood bits.
Nice thing is, you get 10 each of the really useful sizes 5mm, 6mm etc & 5 each of the still useful 8mm, 10mm etc. Sizes range from 1mm to 10mm.
Since I always lose drill bits before I wear them out, this is a godsend! Quality looks OK so far as I can tell, but at this price you can't go wrong.
