Default Minimum Comm size
The minimum recommended comm size for a small diameter armature is .270". The minimum recommended diameter for a large diameter comm eg KR Reedy is .310". I don't know what this is in metric but I'm sure you can convert it

Note: As the comm gets smaller the torque decreases and the rpm increase
