Welcome to the FOG!  You should be able to get the Festool bit thru any Festool dealer.  The  (  Festool USA Website has a dealer locator function.  Additionally there are numerous internet dealers, some of which participate here.  If you scroll down to the bottom of the FOG home page and see a name in blue then you usually will have found a dealer.

I ordered the Festool 20mm bit from Uncle Bob and received it a few hours ago. It looks more like a fostner bit than a router bit.  It really is designed for boring out a clean 20mm hole..

Hey Eoghan,
 Either of these ought to work, if you're just looking for a straight bit, 1/4" shank only though...:

http://www.amazon.com/CMT-811-200-11-Double-Straight-2-Inch/dp/B001NI6PGQ/

I've used the CMT before, it's a good bit.
My first woodworking experience was as a Cro-Magnon. As a six year old, I took silver maple branches, stripped the bark, and washed the sap off the branches. While they were still wet, I would bend them into the shape of a bow, tie them in place, and air dried them for a few days. Then, with my newly made arsenal, I launched homemade arrows at squirrels with miserable accuracy.

I have to disagree. Pls see my thread comparing the two types of bits. That straight bit ain't for plunging.

Looks a lot like the Festool bit. The little perimeter scoring points are the key to a good cut.

Is it really wise to use a forstner bit in a plunge router? I would think the rotation speed of the router is much to high for a forstner bit?

Oops you're right, I stand corrected. It's a fine straight bit of course, the profile isn't that good for plunging those holes the OP wanted. Good catch!

Those CMT bits are meant for boring machines.

The Festool bit I mentioned and the CMT bit that Michael linked to are both hinge boring bits. The Festool bit is for routers and has an 8 mm shaft. The CMT bit is meant for boring machines and has a 10 mm shaft.

Oops... the 10mm shaft spec slipped by me.

I don't have that CMT bit but I do have the Festool bit and while it does bore a clean hole quickly the hole is about .2mm oversize so things like Qwas dogs fit a little loose. But, it's made for drilling holes that cast hardware will be inserted into and for for that purpose slightly over-sized is a good thing.

Well...please notice that Michael and I are not referring to the same CMT part no. The one I'm referring to is a drill/router bit, part no. 392.200.11. According to the CMT catalogue I'm holding in my hand it's a boring bit for hand held drills AND ROUTERS and the shaft is 8 mm.

But it is correct, that Michael is referring to a boring bit part no. 317.200.11
...well according to his link it's a boring bit. But apart from the shaft diameter I don't know the difference.

But I can tell you that I have a lot of both Festool an CMT bits and I consider CMT to be high quality bits.

Kind regards
Henrik

Henrik,

I searched the 392.200.11 number and only came up with the boring bit (if I remember correctly).

Tom is a CMT dealer, I wonder if he can get the 392 router bit and how the price compares to the Festool bit.

But I don't know if it's available in NA. Maybe Tom can answer.  ???

The 392 series bits are NAINA. CMT doesn't offer 8 mm shaft bits here normally.

I showed a pic or two my thread about comparing the 20 mm straight bit with the festool bit. Search for "20mm" may be a space in there). On my iPhone right now.

I didn't think there was much interest in a build thread but I can post one if you want.

I am planning on building one of Ron Paulks work benches. Now that I have this last piece of the puzzle. If the weather holds out I'll start cracking at it.

They're my workbench. Think of it as an MFT/3 that can split in the middle.

Here is another pick of them in use making a 4 foot wide garden gate:

Are your beams torsion box?  It is one of the options I am thinking about as an assembly table.

Almost. I left the bottom skin off so I can  secure the clamping elements from underneath. They will twist a little if unsupported:

I realize this thread is a bit old, but I have the same question: as Michael stated above, if the Festool 491072 produces a larger hole (.2mm) than the standard MFT holes, is there an undersized 20mm bit that produces the same MFT-sized holes?

Or is this something only a CNC machine can cut?

Also, I don't know if CMT's distribution model has changed in the past 18 months, but the CMT 392.200.11 is now available in NA directly thru Amazon: http://amzn.com/B00EV52X64.

Did you ever find a 20mm bit that drills a more proper 20mm hole? Did you try the CMT you linked to?
