Festool Domino cutter stuck

[yellowtruck75]

My 6MM cutter is stuck on my standard size Domino.  I don't want to twist it to hard and have the threaded end snap off.  I used the Domino a few weeks ago and put it away with the cutter on it.  Today when I went to change out the cutter I can't get it off.  The Domino works fine with the 6MM cutter.

Thanks

They do get tight.  Mine was really stuck last weekend and I had to really apply pressure before it popped loose.

It may (or may not) be recommended but I always just screw my cutters on by hand (no wrench) and remove with a wrench.

Yes best to not tighten much at all,I use a spanner but apply v little pressurewhen fitting a cutter  and they do seem to tighten during use, and you do sometimes need to apply more pressure than you are comfortabe with to loosen

Me too. I also put a bit of graphite grease/oil on the thread every now and again which makes it much easier to release a cutter. Perhaps someone with the experience can help further - I seem to remember that there is a place to put a spanner (US wrench) to help counteract the extra force from the spanner used to remove the tool - or am I thinking of something else?

When i change cutters on mine i have to put so much pressure that i wonder how it doesn't snap, i should probably not tension them so much if at all when i put them on again.
Like the saw blade, the cutters tension themselves and hand pressure is probably enough.
So don't worry, just put you whole body weight on the wrench to get it loose, i occasionally put oil on the threads but it doesn't seem to help.

Depending what type of oil or grease it can be a "double-edged sword" -- allowing the cutter to self tighten in use and heat from the cutter during mortising drying (baking) and eliminating lubricity for removal.

...but that is why I use the graphite additive - it does not get removed and does the job.

You notice I didn't highlight "graphite" -- graphite would be good, care of choice of grease or oil is the message.

I'm with Ron, no need for more than finger tight.

I'd prop the shaft on a piece of wood with the wrench parallel to the bench top and then give the end of the wrench a sharp whack with a screwdriver handle. I think that would be less potentially damaging than persistent torque.

just finger tightened for me too. its the same on a mini grinder, you see lots of people tighten the hell out of the disk and can open it then. i neveruse the spaner to tighten the disk only catch the disk and lightly turn it to close it , then catch the disk and turn to open (usually)

They are a bugger once in a while to get off, and I do recall reading that it is known that the "crack" they make when dislodged is quite normal and customary when removing the bits.

I wonder if one of the solutions is by heating or cooling the bit to remove.  You could simply try blowing for a bit the bit with compressed air to cool it, or a hair dryer to heat it and trying to remove (don't recommend a heat/paint stripper gun though).  Not sure which one, heat or cold, is the correct potential solution.  If you do try this, let us know which one works.  On the one hand, I was taught one trick to remove lids on jars was to run the lid under hot water, but then if I understand the old high school physics experiment of the ball and ring experiment, it is cold that should work.

Kevin,

Rather than the "Tool Problems" board I will move it to the "Ask Festool" Board.

Thanks for pointing this out.

The idea would be to quickly heat the cutter (threads) which would expand it & make a looser thread fit to the Domino machine spindle.  The serious point is that it would need to be heated quickly so that the spindle threads don't also expand & null out the advantage.  If you've ever worked on old farm equipment or old cars you know the trick works great on rusty fasteners.
I really question that any Domino cutter could get so tightly stuck to require this process.  [scared]

It could be as simple as debris got threaded in there accidentally when he put it on last.

I was wondering which one of the two in fact would be the right one.  [huh]  [smile]

 

[Jaybolishes]

Just swapped the cutter for the first time a couple hours ago,  wish I had of read this. I snugged it real tight, I can't possibly see how it could get tighter than how tight I set it, but I'll take your words for it. 

 

[Jesse Cloud]

I usually just finger tighten the cutter myself, seems much tighter when I take it off.  Never had a problem.

Would be curious to know what Festool recommends.

Shane, are you there?.....

 

[Rick Christopherson]

When your cutter gets stuck like this, you want to be careful that you don't force the machine out of alignment in the process. Make sure that the force of the wrench is being applied up/down with respect to the pivot motion of the machine. Do not pull sideways. Notice how the wrench in the image below is horizontal and not vertical. If the wrench was vertical, your force would be pushing the mechanism sideways, and this could throw the sweep off-center. When the wrench is horizontal like this, your force will be either up or down.

I hope that makes sense. This was a tip passed on to me from David McGibbon from the service department.

Rick, that is a great tip that I've never paid attention to myself.  I assume this is another of the plethora of omitted user rules that are not included in the fortune cookie length type Festool instruction manual that came with my Domino.  

But does that have anything to do with a bit jam in itself?  Or is that just an aside you're bringing forward somewhat related to this thread in proper bit administration?

I sincerely remain your faithful servant and eagerly await your reply oh master.
