I've had a similar experience with getting them stuck. Seems to me that the drill has to put a lot of torque on these bits to get them through. The problem is that the shafts are small to allow the bending action but yet its hard for a chuck to get a good grip on them. At the same time, the more you bend them the harder the drill has to work. They are certainly useful, however, I always get a knot in my stomach when I use them as they are not 100% ideal. Any suggestions from the rest of you out there on drill/bit combos that are full proof? Maybe its not the drill/bit combo but the technique ... any pointers?
