I was up a two-metre ladder this morning, clearing gutters to reduce the threat of damp to the brickwork below. I think I solved the problems.
For almost all my DIY "life" I've chosen only a hammer drill for masonry work. I have two cordless hammer drills sitting idle because this little 12v cordless is all I've needed for the last two months of drilling. I've put up curtain poles, light fittings and roller blinds and all I've needed has been this little device and masonry bits.
I can heartily recommend the thing.
