"A perfect partner for any 5-qt. KitchenAid® stand mixer that has a tilting head, this flat beater reduces most mixing times by one half. Its innovative diagonal crossbars fold the ingredients together, rather than simply stirring them. Compatible with all 5-qt. KitchenAid stand mixers with tilting heads. With each revolution, the beater fully scrapes the mixing bowl. Attaches to mixer's power hub. Made of coated aluminum."
