Japanese Screw Punch (Push Drill)

[@CarolynJackson-k4s]

Can the bits be sharpened? If so, what sort of tool is used?

[@factformat]

I want the book to lay flat. Can u tie it loosely or do I have to score the pages?

[@eyeonart6865]

Will this work on fabric?

[@AbsentWithoutLeaving]

Can this tool cut thin gauge non-ferrous metal - for example, 24-26 gauge (.50 - .404 mm) silver or copper?

These punch heads are for softer materials like leather. I wouldnt even try it on metal. The materials also need to be soft enough to exit the side port and not get stuck in the head.
