    Granted genuine Hakko 900M tips are probably fine. But the aftermarket ones are a total disaster, as you noted. I have an iron/station with those, and I use it mostly for engraving wood and melting plastic - that's about all it's good for. Soldering? -HA! I can maybe solder two 22 AWG wires together if I crank the heat up to 400C, lol.
    Yeah, it's the tip that came with the hakko iron and it works awesome. Excellent heat transmission, durability, cleans and tins like a dream.

    I didn't realize you could buy name brand hakko T12 tips. For some strange reason I didn't realize the chinese kits were knock-offs of a hakko design. I'll have to add this to my list of projects.

    So, do you use legit hakko t12 tips, or knock-offs?

      Mostly knock-offs. I think I do have one genuine Hakko T12... or at least a very good counterfeit as it works and looks good. But for the majority of time, I use my 5 mm bevel tip. It's over 6 years old now, and I've used it for some really heavy jobs, like melting huge pools of used solder on a DVI connector to pull the whole connector out. It managed to do that without issue. I almost pulled even an entire AGP slot using this same method... but almost. Alas, I didn't want to possibly burn my tip, so I decided to abandon the idea after trying for 5 minutes to keep the whole pool of solder on the AGP connector melted. The station was running on 100% duty cycle for almost a minute - not good for the tip nor the station. The only station I wouldn't worry about attempting this with would be JBC.

        Damn, I wouldn't try an agp connector without some serious hot air and maybe some chip-quik. Pretty impressive that it could keep up though.

        My hakko 888 does have some challenges with large ground planes on some motherboards.

          Well, the above was on an older Dell/Foxconn obard with leaded solder. I might have even succeeded, but 2 or 3 of my 8 blobs of used solder turned out to be a mix of lead-free and leaded, so in the end, the whole mixture became slightly tin-heavy and immediately started to harden as soon as I remove heat away from it.
