I'm mainly going to be using them to open up small holes in 3D printed material and definately not with a dremel. I manage down to 0.5mm in my pin vise but the kit I am working on has lots of 0.3 and 0.2 holes that need opening up to take tiny pins and bolts. Broke my last 0.3mm bits last night and figured I need ones that have a shank that will give me some grip to turn by hand.
The advise is good about buying sets of the most popular smaller sizes as well as multi sized sets
Thanks guys
