What's the best way to punch a hole for an airlock grommet in a plastic bucket lid?
This is what my grommets look like:
I measured the width in the middle area and it's about 12mm or almost 1/2 inch.
I know a regular 1/2" drill will leave a mess of a hole. I was thinking a punch like these from Harbor Freight would be good for the job:
Is there a better way to get a nice clean 12mm hole in a bucket lid?
