Thank you very much for that explanation. Yes I primarily use a 1/8" bit, but I have used these: https://www.amazon.com/gp/product/B07178JW9J/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1
I used both the 0.8mm (1/32") and the 3mm (1/8") with good results, but they have a strange crosscut pattern that I haven't figured out how many flutes they have. I think they are upcut because the material is cleaner on the bottom and it throws the chips up and out. I was planning to buy some bits from Inventables, even though I could source them cheaper on amazon, as a beginner having their guides is really helpful.
