How thick of a board can it punch? Medium chip board?

I don't know how thick medium chip board is, but I was able to punch laminated paper for the cover of a journal I made. Hope that helps a bit.

What size binding spiral will this take? I have 4 holes to 1" binding spirals but it appears it doesn't want to accept it.

Hi! The pitch size for the spiral is 3:1. For the heart, square and circle it's 2:1. WRMK did a brief video dated Feb 2023 and that's where this info is from (in the comments section). Unfortunately I cannot post the screenshot of it as that's not an option here. Hope this helps!

What size coil should be used?

I used the we r memory keepers spiral, but I think any size would work, the length can be cut, but if the book has too many pages I don't think it would open very well.
