Hi There, looking for advice on how to drill a hole for extractor fan ducting - diameter is 125mm
OK, so I'm looking for advice on the right drill to buy + drill bit (I will be buying brand new) - I want a decent drill just for core drilling. By the way, will be drilling through stone and brick (the stone is very hard!). Plus any advice on how to use the drill
Also, to throw a further spanner in the works, there is already an existing hole of about 50mm diameter - so what would be the technique to make this hole bigger? (as there is no 'pilot' hole to help keep it in position).
