New Metro Design’s beater blade is an electric mixer attachment which thoroughly mixes batter, eliminating the need to stop and scrape the bowl manually. Model ka-6lr fits all kitchenaid 6-quart bowl lift mixers. Beater blades are engineered for use with top brand electric stand mixers, including most models offered by kitchenaid, cuisinart, delonghi and viking. A beater blade attachment beats, scrapes, folds and incorporates ingredients thoroughly for fool-proof baking. The new beater blade+ ingeniously improves on the functionality of standard v-shaped beaters offered with high-end stand mixers by crafting a high-quality, enhanced blade that includes a flexible rubber wing down the entire length of both sides of the blade. The durable, food-grade edging simulates the action of a powerful spatula to gently, yet thoroughly scrape the bowl clean. The wing-system design acts like a wiper blade that continuously scrapes sides and bottom of bowl while it mixes virtually eliminating hand-scraping and batter build-up on the blade. Beater blade’s state-of-the-art design continuously and automatically scrapes batters during mixing, which can speed up the process by as much as 50-percent. By eliminating the need to turn off and on the mixer to scrape the bowl, beater blade reduces wear of the motor of the mixer, as well. New Metro Design’s beater blade excels in a full range of mixing applications, including creaming butter, sugar and eggs to fluffy perfection, and preparing frostings and pastry creams quickly and easily. Red colored blades. This mixer is not compatible with KitchenAid mixers KSM657 and all Costco and Sams Club KitchenAid Mixers.
