Domino bits

I havn't try oak yet but have been using cherry, poplar, mapple, birch plywood. I went through a full box of 8x40 dominos (we are talking over 780 dominos) and I do not see any sign of wear on the bit.
My guess is you either hit something either got a lemon.

I've cut a ton and no issues. Luckily, since you no doubt bought the set of cutters, you have that extra 5mm one. ;D ;D

I've cut boxes of tenons in oak, birch, walnut, and other hardwoods and well as plywood of all sorts - still on the original bit and it is still going strong - 5mm. I've done the same with the 6 mm - samo - samo.
They are better than Timex watches ;D

Victor, I for one have not heard of a problem with the bits themselves. I have heard of the tool "jumping" when you try and plunge too quickly. It should be a nice slow steady motion, especially into end grain on hardwoods such as oak.
Side note:
A client of ours just installed and Ipe deck and used the Domino to joint the mitered corners. RW used the 5mm bit, and no issues with it at all. He was so proud, he made me come out in the blistering heat of Nebraska in August just to see it....poor me sitting in a climate controlled facility having to brave the heat.
If I hear anything I will let you know.

Are you using dust extraction with the Domino?
One of my customers came in to purchase 2 more 5mm Domino bits, saying they broke the two they already had in a short period of time.
I asked if they were using dust extraction. The answer was "no". I mentioned the binding I felt when I tried the Domino without the CT running. They didnt want to purchase a CT.
They did, however, purchase the replacement rubber tool connector that fits a D-27 hose to connect to their shop vac hose.

I just broke my 5mm bit today doing some face frame in cherry 
I didn't do anything out of the ordinary, and don't think I hit anything.
The only thing that comes to mine is that I was doing a lot of mortises at once.
Maybe the bit did over heat?

Hello,
I broke a five mm bit. Quite sure I didn't hit anything. Are these bits covered under warranty ?

Hi all,
has anyone tried resharpening the domino cutter bits?
was trying the domino with the 10mm on a piece of scrap and did not notice a hidden nail on the side
ended up with a 1mm rounded end.
if i sharpen it(at a professional shop) would i have the same width of 10mm?
length can be solved with a washer.

As I am reading thru the above posts, and realize some are cutting hundreds of mortices with no problem, while others are evidently havig repeat problems with only the smallest (5mm) bits, I am wondering if experience is possibly the answer in most instances.
I have experienced problems with plunge routing with my WoodRat when i first got it. The mistooks i made at first seemed to disappear as i gained experience with the amount of touch, or lack of force needed for certain operations.
i have had sad experiences with using belt sanders. i would end up with scraps suitable for much smaller projects and finally, when the sander burned up, i decided never to replace it. I figured the problem was not so much the sander, but my lack of everyday experience to get the proper feel for the tool.
In reading above, it seems to be those who ae using the Domino day in and day out, doing literally hundreds of mortices who are having NO trouble. I am thinking it will just be a matter of time=experience for those who are having problems to find the problems disappearing.
Of course, I am speaking from a possition of never having even tried to use the Domino. I will eventually take that step on the SS. Let you all see what happens then :-[

I'm under the impression that the bits can not be sharpened, because they have a unique grind that plays a very important role in how the Domino works, take for instance the chamfered tips, this must prevent burning and make the side to side while plunging possible.
Also, the size of the bit cannot change, the Dominos are so tight with a factory bit.
It would cost near the price of a new bit to sharpen them.

Here is a link to the Festool USA site, Resharpening Domino bits, FAQ section, here is what is says:
Question :
Can the Domino cutters be resharpened?
Answer :
Domino cutters can be resharpened as many as 3 times. After 3 sharpenings they become too short to mortise the necessary depth. Domino cutters will bore between 4,000 and 15,000 mortises before they require sharpening. On average, 4,000 mortises into end grain on hardwood, and 15,000 mortises into side grain on soft wood.
I would gladly buy a new one If they last that long!mastercabman

[/quote]at what cost? and how long will it take to get it back?most of my blades takes at least 2 weeks! i can get a new bit in a day.

Tinker, I don't conisder myself beeing a domino master but I have cut quite some mortises with it.
(I was one of the one chiming in this thread that I went through a whole box of 8X40 dominos).
That's why I was wondering if it could be the bit overheating that could have cause it to break. I don't think I was drilling too fast nor do I think I moved the domino while drilling.
I am not sure how many mortise in a row I did before it happens but I was getting to the end of making the joints for 14 face frames most of them having 16 mortises (8 dominos). I would say I easily did go through over a 100 mortises in a short period of time before the bit broke.
All the cutting parts of the bit have disappeared, maybe the last 5mm of the bit.
