Sorry I never meant to start a flame war. Not so many years back, you could
only get the slightly more specialist power tools like angle grinders, jigsaws,
routers from the "advertised" names. These days you can get more exotic stuff
like biscuit cutters, planers, belt sanders that seem to be (mostly) fine for
the DIY market at a fraction of the price. It just struck me that the angle
drill is a: occasionally quite useful and b: not much more complex to make than
a standard hammer drill. So why isn't anyone selling a "cheepy"?

But thanks for all the response! I've always managed joists with a standard
mains drill and a spade bit (sometimes in an extension). Now I really can't
decide if I must have a mains angle drill for this, or whether I need a "big
name" battery drill, or whether I should wait for a Ferm!
