    I was reading up on how to remove TiN ... it requires very concentrated inorganic acids at elevated temps as cited above, all of which are very hazardous. The organic acids in coffee aren't going to do anything. A curious Russian patent application used a combination inorganic salt solution but again, these wouldn't be present in a roasted bean.

    Basically I see no point in the TiN coating since it seems to flake off under minimal duress, and there is no TiN to TiN contact so lubricity isn't an issue.

    I just feel bad for my friend to have to fork out another $400 (GBP equiv + VAT) for what is meant to be a "lifetime purchase". Plus for anyone else who might be experiencing the same.

    One thing's for certain, given that WW insists on supplying and defending TiN coated burrs, they'll never have me as a customer. Not that I'd ever need it, I have 2 BNZ Conicals, a BNZ Flat, and a Sette 270.

    My Dr friend corrected me on my earlier assertion that Ti metal is safe in the body. Apparently after decades of using Ti in hip replacements it now appears that Ti to Ti contact increases metal serum levels and ongoing research is being conducted into the toxicity implications. He said Ti is no longer used in these circumstances.

    "Don't worry sir, it's proven to be entirely safe!!" ... until it's not.

      Well the Indiegogo campaign has closed, lots of DW comments before and after echeung posted this link, and not a breath of interest from WW/DW.

      Thank you echeung for attempting to raise awareness on the Indiegogo campaign.

        I put the initial question on the IG page for the Key grinder because I thought if one person has experienced it, surely there are others as well. But looking at the HB forums... no mention of it... strange.

        I'm hoping it's just an unfortunate one off, surely if it was more widespread there would be a lot more talk about it on various forums.

        one would think if there was an issue with them, there would be many posts about it on other forums. Even if there was a bad batch.
        WW arent the only ones who use this coating.

        No excuse for no communication though.

        Hasnt put me off i am very much looking forward to getting my key grinder

      Dr friend received his genuine Mazzer burr set last week and installed them immediately, happily grinding away each day.

      I agree JohnA, if it was a bizarre one-off occurrence why did he not dig through his emails, contact my friend and even try to sort something out?

      When you get your Key, please post back on this thread after about 8-12mths with an update on how your TiN burrs are coping.

      jasiano ... I don't have a HB login so I didn't post the question there, maybe I will at some stage. Thanks for raising the issue in the thread, it wasn't apparent you did this.
