Topic tags/keywords: router bits three flute mlcs

Does anyone have experience w/ the “TripleWing” router bits from MLCS (and I assume others make them as well). The price doesn’t seem to be that much more than the two-flute counterparts. MLCS claims that they give a “smoother, cleaner cut.”

How about it? Two-flute or three-flute? MLCS or another supplier?

I have not used the CMT triple wing bits but, I have three new Freud Quadra cut bits, of different profiles.
I am more than satisfied with their results.
With that said, I would say you would have to compare a profile cut by a new 2 fluted bit to the same profile of that of a new Quadra cut bit.
Chances are a microscopic examination would be required.
IMO the more shearing surfaces passing over the wood should give you a cleaner finished product, -or- allow an increased feed rate, and less waste being removed by each shearing edge the carbide edge should stay sharper longer, if in fact the carbide is of equal thickness and quality on each of the two styles of bits.

For what it’s worth, I have not read an unbiased controlled test of either brand. I have only read the promotional hype printed in the Company’s advertising and promotional material.

CMT is a respected Mfg. of quality bits, no reason to think their new product would be any less.

I’ve used CMT triple wings and an off brand from Peach Tree.
Both give a very smooth cut. Not enough milage on either to test durability.

I did find however, the triple wings “seem” to leave a smoother finish than the quad cut Freuds.

Would like to do a “definitive” test comparing all brands with the same profile.
Hardwood, softwood, feed rates etc.

Whether with a router bit or a saw blade, when all other parameters are equal, more cutters should equate to a cleaner cut. Along with a cleaner cut comes higher resistance and more chance of burning. The number of cutters is only one of several parameters that effect the cut…it just happens to be the easiest one to spot.

Is CMT the same as MLCS?

I prefer the whiteside compression spiral bits to any amount of flutes when I need a really clean cut (especially pattern routing)

”Is CMT the same as MLCS?”

No…AFAIK CMT is an Italian company with no association to MCLS that I’m aware of.

If you have a variable speed router and can reduce speed, then the 3-wing bit will indeed stay sharper longer (speed kills). Actually it’s heat that dulls edges. Faster feed rates don’t mean much since handheld operations need to be carefully done anyway. So reduce rpm but maintain normal feed rates. If you don’t have variable speed then you need to increase feed rates to avoid burning (this doesn’t sound good to me).

I run large custom router bits on stationary, power-fed machines and switched to 3 wing cutters years ago. They run at half speed.

There are other opinions (especially from manufacturers who don’t offer them).
