Kitchen Aid hand mixer TurboBeater. Please note that these will only fit the Newer KitchenAid Hand Mixers made since 1997. This is due to a difference in receptacle design. Look at the holes the beaters go into. It shoudl be round with two slots not round with four slots. Self-cleaning stainless steel beaters mix chocolate chip cookie dough easily. These stainless steel beaters cut cleanly through the heaviest dough and are dishwasher safe. Genuine KitchenAid part.
