I have the old non-angling one which works pretty well to drill 1/2"
holes in steel plate. I wouldn't want to stress it with a larger
drill. They are fussier to align than a mag-base drill and need to be
clamped down, but they are light enough to position on a vertical
surface with one hand, for instance to drill a wooden door.

It takes quite a powerful magnet to resist the quill handle leverage.
