Now I am as much an expert at this as chuck c is at WWI aeroplanes.
But it sounds to me like you are heating the Allen Wrench up and
tempering the metal. Then when you try the second bit, it tries to
drill really hard metal and "totally dullsville" is the result.
Try turning the drill bit slower, with not as much force, and lubing
the bit with cutting oil. May take longer for each wrench, but how
long you been doing this already?
