    Domino Question

    Hi guys, I was using my Domino 500 the other day with the 5mm cutter. To my dismay all of a sudden I heard this grinding sound. I discovered that the bit had broken off about quarter of an inch from it's end and was floating around in the mortise hitting the remaining bit. Is this a weak point with this bit.... have this ever happened to any of you. If not, I suppose there could have been a flaw in the metal or if not... something with my technique? Maybe I was plunging too fast. It didn't seem like that was the case. I was using cherry, so the wood was not particularly hard. Thanks.

    They break, keep a spare.

    Were you using dust extraction with the domino? I've read the bits are more prone to breakage without a DC hooked up to it. I've used my 5mm cutter a good bit for smaller parts and never had an issue.

    It's Festool. Comes with the territory.

    CMT makes cutters for a lower price than the Festool-branded ones. I have had decent luck with them. At least, if you find yourself having to pony up for replacements, then this may be a compelling option.

    You could have hit something in the wood or perhaps it was a "4:45 pm Friday" time when your cutter was made.

    I haven't broken any of mine but I am on second bits for the 4 and 5 mm ones just from wearing them out.

    It is always a good idea to take a quickie scan of your cutters before using them just in case you find any raised burrs that one stroke of a file could remove.
    Wood: a fickle medium....

    Did you know SMC is user supported? Please help.

    Sound advice.
    If at first you don't succeed, redefine success!

    Yeah I am pretty sure nothing was in the wood. I am guessing it was the "4:45 pm Friday" thing
