Default 1/8" EM with 3/4" Cutting Length?

2 Newbie Questions:

[1] When looking at router bit specifications cutting length is the "maximum" material thickness that it can cut correct?

i.e.
Cutting Diameter: 1/8"
Cutting Length: 1/2"
Shank Diameter: 1/4"
Overall Length: 2"

[2] Where is the best place to find a 1/8" EM (Or alternative with 1/8" cutting diameter) that can cut 3/4" thick material?

I have looked around at US Router Tools and can't find a 1/8" EM with cutting length over 1/2"

I did find a bit on Amazon that looks like it might work, but not sure as it is 4 flute and I remember reading the other night on the forum that 4 flute isn't a good idea for some reason:

http://www.amazon.com/gp/product/B00...A1IPHIYKH2PUAP

I've been making some samples of table numbers and other signage for a local wedding. All good on the signage, but instead of 1/2" for their table numbers they want it in 3/4". Some of the words and numbers due to their selected font requires the smaller cutting diameter.

Thanks

I just ran across this thread on long router bits:

Try Toolstoday. Thinks it's a compression bit. Kinda pricey.

Look at Amana 51446 at ToolsToday- If I read specs right it's 3/4" cutting length, single flute upcut.

is this 2d or 2.5d(3d)?

I use a 1.5" 1/8 bit to cut 3/4 mdf but use a 1/4 bit for a rough cut down to .70 then do the last .05 with a 1/8 bit with a 1/2 inch cutting depth.

It will cut closer to the shape than the 1/4 bit does but does it in 12 passes taking .0625 cuts. The majority of the material is cut with the 1/4 bit and make for a lighter load on the 1/8 th bit.

It takes longer but you don't have to worry with deflection of the bit like you would with a 3 inch 1/8 bit

It is one work around, not the quickest but it works

Thanks all. Ordered a couple bits from the above recommendations.

@Dana - 2D. Workaround makes sense. I will give it a try. Thx !!

Found this bit on Amazon. Not sure if I can use this? Doesn't say CNC in the description... Will do more research, but thought to post here to get some opinions:
