Compression spiral.
Seen lots of debates about which is the best bit for mdf.
I find 2 flute 6mm upper cut reliable, but leaves a fuzzy edge at the top edge. (And I hear Down cut does same to bottom edge).
Is a straight single flute a better option? Will it plunge as well?
I have made a small table and its a pain sanding the edges after cutting. Want to know for future projects.

Not sure what you mean? They are made for making full depth cuts in one pass.

You shouldn't be plunging at all. Always try to ramp into the cut.

Thanks for your answers ger21.
Does that apply to holes too? it only plunges to start the cut and a few holes here and there.
I'm cutting at approx 24,000rpm (Kress 1050) 3mm passes in mdf with 6mm twin flute spiral upcut atm. (top edges are very furry and require sanding).
