https://www.axyz.com/when-do-i-use-an-o-flute-bit/ https://www.endmill.com.au/blog/what-the-flute-a-comprehensive-guide-to-cnc-router-bits/ I use for aluminium with a router table the advantage is they are much less likely to gum up than a normal helix and are better at heat dissipation, they are available with flute direction of upcut, downcut and centre profile (for different materials) and given they only have 1 cutting edge have a lower feedrate when used in a router spinning at 20,000 rpm against a higher number of flutes cutter. I haven't needed to use them for a while but they are useful to know about to cut aluminium on a router table.
