Fits models K45, K45SS, KSM1, KSM75, KSM8, KSM9, KSM90, KSM95, KSM100, KSM103, KSM105GBCER, KSM110, KSM120, KSM15, KSM150, KSM150PS, KSM155GB, KSM152, KN15E1X and others. 4.5-5 QUART FLAT BEATER: When using a stand mixer to knead dough, the stainless steel spiral K45DH dough hook is an ideal companion. The dough hook helps develop gluten in the dough, which traps air and results in smooth, chewy texture. Ideal for mixing bread dough, pizza dough, noodle dough, and cookie dough.

Please note: Do not operate the dough hook in a dry bowl. PLEASE NOTE: This is a non-original part, fully compatible with 4.5-5 quart tilt-head stand mixers. Not compatible with bowl-lift mixers. For safety, do not use in glass bowls or dry bowls. Easy to clean by hand or in the dishwasher. Resists rust and mold even with prolonged use.
