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.

I ruined a handmixer that way. I was kneading breaddough with it and indeed the engine couldn't cope and overheated/stressed out. I had to buy a new one. So be carefull. And indeed, it wasn't easy at all to hold the mixer or the bowl with the dough..

As previous answers suggest: These hooks tend to come with most hand mixers, if they can be used, used with what kind of dough, and with what amount of dough is very model dependent.

From my own experience with a standard Siemens device (mymix 300W, specified as 0.5kg total weight in mixing bowl): recipes up to 500-600g flour will in practice work well (less for very heavy doughs). Making too wet doughs is not a good idea with that type of dough hook - since they have little working surface but high speed they will lose all "traction" on the dough if it is drippingly wet.

The advantage compared to hand kneading is that it is far easier to thoroughly incorporate an ingredient late in the kneading, and that you don't get the "kneading dough is nice, you get such clean hands from it" effect. Also, with some doughs these devices work very quick - minutes to a reasonably smooth dough. Disadvantage is the more restricted hydration range, and more disruptive action (these hooks can saw a ball of dough in half if applied from the right angle).

Physical strength is needed to control mixer and bowl, so there is no clear advantage there compared to hand kneading.

I just made texas roadhouse rolls (4 cups of flour and about 3 cups of other ingredients) with a ge 300 watt hand mixer and dough attachments. The mixer handled it perfectly fine... I on the other hand found it difficult to hang on to the bowl and mixer but it is definitely doable.

I just used the dough hooks with my hand mixer, I found it surprisingly easy to hold (the counter rotation of the hooks meant the forces mostly cancel out) and my mixer didn't seem to have any trouble going at any speed through my reasonably dense dough. I guess it largely depends on the brand and usage and a little luck, I would certainly be a bit more careful next time after reading some of the comments here though as I like that hand mixer and don't want to kill it. It's not bottom or top of range, but it has digitally controlled speed not mechanical switches, which is what failed in my previous mixer.
