My hand mixer came with dough hooks, can I knead dough with it?
If you do most of the kneading while the dough is very wet (like Jeff Varasano recommends for his pizza dough here http://www.varasanos.com/PizzaRecipe.htm), you should be able to do most of it with even a comparatively weak hand mixer and not have too much trouble holding it steady enough (see link - gluten IS working even though the dough is still only slightly more dry than a batter).

That said, if you try to work with a drier dough, even if your motor can handle it (which it likely can't), it will probably be more difficult to hold the mixer than to just knead the dough by hand.
