festool router bits
« on: March 12, 2018, 04:55 PM »
A bought a couple of Festool router bits a while ago and
haven't looked at them till today. I now noticed that
the shaft is not full/solid metal but rather hollow/threaded.
Could someone tell me why they are hollow/threaded -
surely it is not as good as full metal ?

Weird. Ive never owned one. Never thought they were worth the cost when Whiteside bits are so nice!

Sounds like a bit for the Domino. What is the part number / photo..?

For example, here's a Domino 700 cutter / bit

I have a couple of Festool router bits with the interchangeable carbide inserts in 8mm and both shafts are solid.

I just went to check, all of the 8mm shank festool bits out of the caroussel set have solid shafts.

I remember that, what I thought was a 5mm straight bit,  I bought per accident once, had a hollow/threaded shaft, and that bit turned out to be for boring the 5 mm holes for the lr32 system (I wanted to check that one, but I no longer have it (it probably was in my of1010 systainer when it got stolen).

I just found out that one of my most used festool router bits also has a hollow/threaded shaft, it's an 18 mm straight bit with reversible/replacable bottom and side inserts. I don't think it's significantly less strong, because it's only the top 8mm that is hollow, and it's supposed to be inserted at least 25 mm into the collet, according to the markings on the shaft.

I thought that on the 5 mm bit, it was for mounting on different machine, like the bits for the domino mount, but then on a doweling machine; but I think that on the bigger bit it was part of the production process of the bit itself. to temporarily mount it for machining the sides/tapping the screwholes/whatever. (I'm fairly clueless on how those bits are made, just my imagination ;))

/edit: btw: I also checked the festool 45° bit for making folding miters on plasterboard, it has a solid shaft.

The bits that came with my Festo lr32 are hollow/threaded. I've bored thousands of holes with no issues.

For a second I thought I did something stupid - buy domino cutters, but that's not
the case - these are the cutters I bought:
fi5x53.5x8   491066 031 029
fi5x53,5x8   491064 031 029
fi10x60,5x8 491069 031 T31
fi8x53,5x8   491068 031 029

OK, then I don't worry about it and just use them - thanks for all
the feedback !

Those are boring bits. They often have threaded hollow shaft to fix into boring machine (besides plunge router).
