    Often the stuck drill-bit breaks again, because the metal has been
    compacted and forged around the drill bit, when you try to remove it
    by a reversing action. It is hard to believe that this tool will do
    a good job for a.5 broken bit??? Mostly the drill breaks at the very
    end, when you almost through silver or so and in that case you can
    try to use another broken (softer) ball burr (.5mm) shaft as a punch
    to drive it through (first annealing will help). When it stuck half
    way I found that long annealing soften it just enough for drilling
    out the stuck bit (not brilliant for the new drill, but it does
    drill out). 'Burrlife', or similar will avoid the drill to clock up
    in the first place.
