No, not an orchestra,
Doing some cedar stuff and was looking at one my older well used CMT trimmers. I have been using two flute flush trim bits forever but wondered what the advantage, disadvantage of a three flute flush trim bit? More even cut? Faster? Just noticed them in the Whiteside book. I use them for “up trimming” in a table for below pattern cutting.
I’m only wondering about the flutes, not the brands : -)
Anyone?
Thanks

Boiler,
Router bits are just like saw blades - more cutters mean a smoother cut, but a slower one. I've seen one-flute bits also. As an aside, I bought a 3-flute set from Dimar Canada sold under the Woodpecker brand. I've been very happy with them, and the bits are top-notch quality. Also quite inexpensive.

Two flutes cut faster. Think of rip blades, less teeth cuts faster.
Find flush trim bits with a "shear" action...The carbide runs at an angle along the length of the bit and shears off the wood, like a scissors.
Most of the shear bits are down angle toward the bearing so it wouldn't work for my needs but if someone ever came up with a two flute upshear well then...Thanks

Try pricecutter.com. They have a 1/2" upshear solid carbide trim bit. Kinda pricey, though...
Couldn't find it At Price cutter with a bearing. Maybe didn't look in right area. The flush trims they did have are two flute.
Thanks though for looking.BB
Try part #P12-2000, and all their spiral carbides with bearings will come up.

P12-2006 might be the ticket,
thanksBB
Great!!
Glad to help.

Also try mlcswoodworking.com, #7399, for thirty bucks less. Or you could order just a solid carbide upcut, then go to your local bearing supply, get a bearing to press fit onto the bit...save lotsa bucks.
Tell ya what..I'll buys it and you presses it. If I did it - the pattern would go spinning off into Dr.Who land. :-)BB
No sense of adventure, eh?
Piece of cake...all you need are a woodworking vise (or even a pipe clamp), a proper size deepwell socket (or pipe) and a drop of oil for lube.
Or a friend who knows how.

Strike that last worthless piece of advice from the record...must have had a case of brain freeze. Wouldn't work for a flush trim. Now, if you have a friend with a metal turning lathe... Forget it, just buy one and it's done right.
You may try these:
http://www.mcfeelys.com/search/upshear
http://www.integratooling.com/prodinfo.asp?number=1054-UP
The top one is pretty pricey, but the bottom one is on clearance if you just want to see how the upshear would do for you.
The Mcfeeleys bits are really interesting. Different spin as it were :)
The carbide and cut pattern might balance out for speed and smoothness.
Thanks,
I don't think the Integra would work for my needs as a table mounted pattern bit without a bearing.Thanks againBB
Hope it works out well for you.
