This blade is especially designed for 21.5" A1418, A2116, 27" A1419, A2115 & iMac Pro A1862 but it can also be used for iPads, tablets, phones, MacBooks, and other devices with similar build and design or digitisers/ adhered parts but I would say with these tools your skill can decide the limit as in my opinion this is a multipurpose tool.
