What sizes of drill-bit are most useful for general interior DIY ?
If I wanted a selection of the "most common" sizes for little jobs around the home... like to drill in to plaster to put a plug in and fit something general like this...
What sizes would be best to have handy. (I want to get say 3 x each of the best sizes so I have replacements ready in case they blunt or break). I doubt I would need the really big massive drill bits anyway.
However what confuses me is that in UK at the site I shop at they only offer sizes in "mm".
Example: 3mm (which is probably too small for use with a plug maybe?)
