Single Flute Router Bits?

[Paul Fitzgerald]

I don't have a router that will accept bits with 1/2" shanks, and I need a 1 1/2" straight bit. The only one I've been able to find is the Freud 03-140, which is a single flute bit with a 1/4" shank.

Is there a big difference between the single and double flute bits in terms of usability or application?

Thanks,

Paul

Paul, I would keep looking. It seems that a single flute bit would put stress on your router due to it being out of balance though I may be wrong. I have a couple 1/4 in bits and they have 2 cutters. Check Whiteside, CMT, Infinity,Sommerfeld. Does it need a guide bearing?

From one particular distributer of Amana bits:

The Single-Flute design allows for faster feed rates, greater chip clearance and maximum stock removal. The 2-Flute design allows for greater balance and a fine finish.

My experience is in line with that statement, single flute for speed, multiple flute for smooth finish.

Paul, generally when people say they want a 1 1/2" bit, they're talking about the diameter. Maybe you're meaning that you need a 1 1/2" cutting length?

Oops! Yes, I need a bit with a 1 1/2" cutter length, not a 1 1/2" cutter diameter.

Enco (www.use-enco.com) has a solid-carbide end mill which is 1/4" shank, 1/4" diameter, and 1 1/2" cutting length. It will cut wood just fine. McMaster-Carr has them too. www.mcmaster.com

that would be the way to go. there will be some flex in it. I have used them on my cnc machine. only take 1/4" to at most 1/2' off at a time with it. then a cleanup pass at full depth.

Hi Paul

Not to take anything away from MLCS, they're fine. These guys are closer to you, however and sell good stuff.
