Thanks for all the help, and that video. I was a bit frustrated so ordered 1/8 bits and walked away from it. With all the great tips you guys provided, think I’ll mess around with my 1/4 bits today and see if I can get acceptable results.
I think when speaking of these bits there is some confusion on sizing. If your bits are 1/4" radius then you're probably right and they're likely too big. That would make them 1/2" across in total.
If they're 1/4" across in total then they're probably ok. I believe these bits are sized by the radius so a bit that was 1/4" wide overall would be a 1/8" radius. But many times people, and also the places that are selling them, will refer to 1/8" radius bits as 1/4"
