About this Item

K400 Variable Speed Blender with Tamper

The performance to deliver the perfect taste for every blend. The K400 variable speed blender's 3-part blending system easily blends even the toughest ingredients for a consistent texture. The ribbed jar design creates a powerful vortex, pulling ingredients into the unique asymmetric blade that cuts at four distinct angles, ensuring your ingredients are thoroughly blended. The Intelli-Speed Motor Control then senses contents and maintains the optimal speed to power through all ingredients, from kale to almonds and more. Whether you're creating fruit smoothies or prepping a fresh marinade for a dinner party, control the taste and texture of your blends with the 5-speed variable speed dial, or use the 3 Preset Recipe Programs: Ice Crush, Icy Drinks, and Smoothie.

Features:
Quickly Blends Even the Toughest Ingredients
  • Take on notoriously tough ingredients like kale and almonds with ease, so you quickly turn whole foods into smoothies and enjoy.
Easily Create a Range of Textures
  • The variable speed dial blends however you need, from smooth to chunky, or select from 3 preset recipe programs: Ice Crush, Icy Drink, or Smoothie.
Guide your Ingredients to the Perfect Blend
  • Use the included tamper to push stubborn ingredients into the blending vortex for expertly even blends.

Customers Say

AI-generated from the text of customer reviews

This versatile kitchen powerhouse combines professional-grade performance with thoughtful design elements that make daily blending a joy. The robust motor effortlessly transforms challenging ingredients into silky smooth results, while maintaining surprisingly manageable noise levels during operation. Its retro-inspired aesthetic and premium finish options make it a proud countertop fixture, though its substantial weight means you'll likely want to find it a permanent home. The intuitive controls and preset programs make it accessible for all skill levels, while the self-cleaning feature simplifies maintenance. While some users note occasional concerns about the plastic jar's long-term durability and staining, the generous 1.7L capacity and effective tamper tool ensure consistent results for everything from morning smoothies to hot soups and homemade nut butters.

Rated 5 out of 5 by from Great blander! For price and power, this Kitchenaid blender can’t be beat! My husband and I use this as a blender and food processor. It’s amazing. I mix smoothies and he mixes veggies for recipes. And the cleanup is no sweat. In the dishwasher it goes.

Rated 5 out of 5 by from Easy peasy clean up [This review was collected as part of a promotion.] I was gifted the blender and it has been a game changer in the kitchen. So easy to use- even easier to clean. I hated having to take my last blender apart into 1000 pieces. I used to avoid using it cause I hated cleaning it. This beauty cleans up gorgeous with some warm water and soap blended right up. Now it’s all smoothies and sauces all the time! Thank you!

Rated 5 out of 5 by from Love it! I love this blender. It makes awesome smoothies. Grinds up frozen fruit in a flash without jumping across the counter. Clean up is a breeze, a little water in the pitcher with a couple of drops of soap, a quick cleaning blend and you're done. No blades and seals to reassemble. Highly recommend!

It has been a great addition to my kitchen.

Rated 5 out of 5 by from Great blender! [This review was collected as part of a promotion.] I bought this fantastic blender last month and it has not disappointed. This is definitely the best blender I’ve ever owned. It is very powerful, powerful enough to handle all of food that you put in the blender. I have a wait problem, not being able to keep on my weight so my nutritionist suggested that I did more smoothies and protein drinks. So I bought this KitchenAid blender and I am very satisfied with this purchase. I would definitely recommend this blender.

Rated 5 out of 5 by from Great product and great customer service! [This review was collected as part of a promotion.] Great warranty coverage and customer service. We bought this blender model several years ago. It's always been great, with a flawless motor and blades. But when the plastic jar started to leak through the bottom, we had a warranty issue. KitchenAid promptly replaced the entire unit at no cost. Thanks!
