The back door looks like it was installed a quite a few years ago. This is the style of door handle:
I've replaced the barrel with an avocet euro cylinder and the sashlock has been upgraded to a modern yale/union one but the door handle is still old fashioned.
I can't seem to find a euro handle that will fit as a straight swap. The modern ones are much taller and hence I'm faced with the prospect of making my own holes.
Is there anything I need to look out for whilst drilling into an aluminium door? Can I use my Titan HSS drillbit?
