This premium replacement kit includes a hardened stainless steel cutter blade and a durable drive socket, designed specifically for Vitamix Advanced Series models including Touch, Go, and Quiet One. The blade never requires sharpening and features double stainless-steel bearings for extended life and quieter operation. The kit allows for quick, on-site replacement with compatible containers. Compatibility: Fits standard household 64 oz and 32 oz containers, as well as standard commercial 64 oz, 48 oz, and 32 oz containers. Please note: This kit does NOT fit new household low-profile 64 oz or 48 oz containers, nor commercial MP, XP, Advance, or XL containers. The drive socket is not for use with the Vitamix XL model. Constructed from high-quality metal and plastic, the drive socket safely couples the motor to the blade assembly and protects the motor if rotation is blocked. Installation is a simple DIY process, typically taking about 10 minutes with the included hex wrench. Package Contents: - 1 x Stainless Steel Blade - 1 x Drive Socket - 1 x Hex Wrench (color may vary) Note: Slight color variations may occur due to photography and monitor settings.
