Please Note: The TH-M BeaterBlade is designed exclusively for KitchenAid 4.5 & 5-QT "Tilt-Head" mixers. These Tilt-Head mixers are the cornerstone gems of the KitchenAid legacy as it pivots backwards to reveal the mixing bowl. The TH-M BeaterBlade fits the 4.5 and 5-Quart metal bowls and the 5-QT glass bowl for KitchenAid Tilt Head mixers only. The TH-M will NOT fit the 3.5-QT Mini, any "Bowl Lift", nor any non-KitchenAid brand of tilt-head mixers. The fundamental building block of cakes and cookies is creaming butter, sugar and eggs. BeaterBlade scrapers push sugar into the mixture, creating the fluffiest, most aerated batter you’ve ever made. BeaterBlade Metal is our most up-to-date version featuring lead free powder coating, unique laser etched serial numbers, double overmold blades for sanitation and over 15 years of our experience and customer service. Compliant to both California Prop 65 and FDA 21 CFR 175.300.
