What is one function of the microstop cage in countersinking?

The microstop cage serves a crucial function in the countersinking process by ensuring that the countersink tool remains perpendicular to the material surface. This alignment is essential because any deviation from the correct angle can lead to improper countersinks, which may affect the fit and strength of the fasteners intended for the material. A perpendicular approach also helps achieve uniform depth and smooth finishes, both of which are vital for structural integrity in aerospace applications. By maintaining this alignment, the microstop cage produces more precise and consistent results during the countersinking procedure.
