Questions about this tool

What does R7 describe?

It is the radius of the curve the tool cuts at that position.

Which option is better for one small radius?

The R3 lever punch is dedicated to a smaller radius. Choose this tool if you want several sizes in one body.

Can I round a finished bookboard with it?

Check the allowed stock first. A paper punch may have too little clearance for a covered board.
