Is there such a gadget that can drill around corners? I have just bought an expensive made to measure blind for the kitchen which fits outside the recess. Took old blind down and filled holes, papered over etc. Can't now fit the new blind because there's a kitchen cupboard in the way (sideways on). The old blind must have been fitted prior to the fitting of the kitchen. Short of taking the whole row of cupboards down off the wall, disturbing tiling etc how can I drill the holes for the bracket?
