Hi all.
I need to get a countersink bit with a body diameter of minimum .775" for the M8 screws that I'm planning to use in aluminum and mild steel.
The 3/4" bit will be too small so I've been searching online for a good 7/8" or 1" countersink bit,
I have never owned a zero flute bit, all I've used have been single flute and a couple of 6 flutes, which all performed equally well ,what's confusing is what 's called "chatterless" countersink bits ,it seem to suggest the more flutes a bit has the less chatter it'll produce but on the other hand I have read posts here praising the zero flute countersink bit as the better performer , so here's my question: do I stick with a single flute bit since I know what to expect or do I get the zero flute and hope it'll cut a smooth CS ?
I looked around ebay and amazon, there's a lot of cheap bits for sale and almost all claim to cut metal but one item I found that sounds good is KEO brand :

Please let me know what you think.
