Does yours use a 6 quart bowl?
Yes - I'm using the 5-qt bowl that came with the KA K5S (my friend lent me the bowl and the standard attachments that came with that mixer when she purchased it) - the white-coated dough hook also came with the K5-SS. The uncoated dough hook is from my KA K5-A which also uses a 5-qt bowl. That dough hook fits the K5-SS but it extends to the bottom of the bowl and mixes dough just fine.
I know the K5-SS is an older model but it was popular in its day. The shorter dough hook is sturdy, as it is made of heavy metal with a white coating but I can't understand why it is so short. It just doesn't reach far enough into the dough to knead it properly.
