The Milwaukee 40-50-1330 is a genuine OEM cylindrical helical compression spring designed to resist compressive axial loads, storing energy when compressed and releasing it as a restoring force. This steel component is used across various Milwaukee cordless and corded grinders to maintain gearcase structural integrity, provide return force on depressed buttons and levers, pre-load bearings and clutch mechanisms, maintain detent engagement in selector mechanisms, and drive ejector and release functions.
