Blendtec blades are made of cold-forged hardened steel and are up to 80% thicker and 10 times stronger than other blender blades. The modern touch controls not only look great, but make everything from blending to cleanup easier than ever. Instead of relying on breakable plastic parts to spin our blades, all Blendtec blenders feature a hardened metal drive socket. It never slips or needs to be replaced, so it stands up to heavy use year after year. Our motors can blend even the toughest ingredients, like ice, frozen fruit, and raw veggies, to a perfectly smooth consistency without skipping a beat.
