Falcon NL/HB Cylinder Template

I am a chat assistant. I have analyzed the provided document which is a template containing instructions for preparing doors using FALCON's 1690 device with NL or HB cylinders. This includes detailed drilling, countersinking, and reaming specifications. I am ready to answer your questions regarding this template.
What cylinder types are used with the 1690 device?

What is the diameter for drilling through the lock stile?

What is the countersink diameter on the inside face?
