1-3/8" and 2" pads produced by the XP-1 and XP-2 are perfectly sized for your iBrid nano, LD-30, TA-50, and a variety of other machines on the market.
2-3/4" pads produced by the XP-3 will fit any 2 1/2" to 2 3/4" backing plate. The founders of KXK Dynamics use RUPES line of incredible machines day in and day out.... so for your "RUPES Mini" backing plate they came up with an ingenious solution... Punch it!
The XP-3 Pad Punch's diameter is slightly smaller than standard 3 inch backing plate diameters, and you may ask why. And the answer to you is: a higher pad yield, AKA more pads punched out of a 6" microfiber pad. But have no fear, it is a very simple backing plate modification that can be accomplished with, you guess it, the XP-3 Pad Punch. For most 3" backing plates, the XP-3 Pad Punch can be used to "trim" a slight ring off the edge of the plate to match the pads you will punch.
For those of you that do not use 1", 2", or 3" pads very often this kit is not a necessity... However for those who utilize 1", 2", and 3" pads, the KXK Punch Kit is a no brainer!
