I drilled a hole for a 15mm pipe with an SDS drill I borrowed through a
plastered block internal wall. Trouble is, it was out in the vertical
by about 5-8mm. No amount of wriggling seems to get it in line - the
ends just get bigger! I think the answer is probably "no", but just in
case, is there any cunning way to move such a hole upwards by a few mm?
Thanks in advance,

John
