Do you know where I can get that kind of foam that I can use for like a handle? it already has a hole in the middle of it and it has a slit to where you can fit it around something.
I'm assuming that the quality of the hole saws can be fairly low-mediocre since it's just being used for EVA foam. Judging by the case, it looks like you're using the Luckyway 17 piece kit sold on Amazon. Thanks for the video.
Mine are just standard hole saws, nothing special. I use a cheap hole saw kit from harbor freight. It gets the job done but it can leave rough edges if I'm not careful.
