Made of Marine Grade 316 Stainless Steel, very tough and resistant to corrosion A special bit key to remove the screws on the back wall of coffee machines Extra long (2.4 inch) Magnetic (custom added) The key ring moves freely and immediately applicable or can easily be removed so that you can use a regular driver handle for access in the tightest places. Traditionally the screws are obvious and appear as black rivets. However, on many of the more recent models Jura has hidden the screws which makes it less obvious how to disassemble the machines. You may find this additional info helpful: J-series, Z-series, and X5: There are two hidden security screws behind the Jura logo in the back. Turn the logo an eight of a turn clockwise (Z-series/X5) or counter-clockwise (J-series) to release it and you will find the screws. ENA-series: These machines are secured with a locking mechanism. There is a security screw behind the Jura logo in the back. Turn the logo to counter-clockwise release it and you will find the screw. Remove the screw and then push the gray plate upwards to release the locking mechanism in the back. Likewise, theres another oval head screw in the front that will be visible when you pull out the tray. The locking mechanism in the front needs to be pulled down (in contrast to the one in the rear that moves upwards) Fit for Jura, Capresso, Krups, Franke, AEG ,Orchestro, Siciliana, Toscana, and all Nespresso machines The bit will fit the proprietary oval head security screws in the following machines: Jura-Capresso: A1, A5, A7, A9, C5, C50, C55, C65, C70, C75, C9, C90, D6, E5, E8, E9, E10, E25, E30, E40, E45, E50, E55, E6, E60, E65, E70, E74, E75, E80, E85, ENA3, ENA4, ENA5, ENA7, ENA9, ENA Micro 1, ENA Micro 5, ENA Micro 8, ENA Micro 9, ENA Micro 90, ENA Micro Easy, F5, F50, F60, F70, F90, F7, F9, F900, Giga 5, Giga X3, Giga X7, Giga X8, Giga X9, XF50, XF70, S50, S55, S70, S75, S85, S90, S95, S7, S8, S9, J5, J6, J9, Z5*, Z6*, Z7*, Z8*, Z9*, X5*, X6*, X7, X9, X30, X70, X90, X95, Ultra, Cappuccinatore, M30, Scala, Scala Vario, Evolution, 201, 300, 401, 500, 601, 801, 2000, 3000, 4000, 5000, 6000 Capresso: C1000, C1300, C1500, C2000, C3000 AEG Cafamosa: CF 80, CF 81, CF 85, CF 90, CF95, CF 100, CF 120, CF 200, CF 300, CF 400, CF 500 Krups: Orchestro, Siciliana, Toscana, and all Nespresso machines.
