Interesting video of him testing 10 bits from different manufacturers:
TL;DW:
Basically, no bits broke, the more expensive bits did somewhat better, watch out on the real cheapies that you actually get what you ordered.
I watched it a couple of days ago. I thought it was an interesting comparison, but it still had a fair amount of subjectivity to it. Because of that variable, I feel that any of the top 5 would be good choices for me, with the caveat that going cheap might be warranted if I have some ‘one off’ project that I think I will only need a bit for that one project.
As a company that sells cutters, this is what we tell customers when we speak 1-on-1:
Buy a good cutter and it’ll work well. There’s not much magic in anything, especially at the power levels and materials that we’re talking about here. Some geometries work better for one application or another (like single-flute cutters), but generally speaking, if two quality cutters have similar specs, they’re going to perform similarly.
