    Default Where can I get a quality miniature drill chuck?

    As above, looking for a miniature drill chuck that isn't hobby quality, and isn't one of those finger-feed ones. For holding drills and reamers in a CM-1, ISO-20 taper, max chuck body diameter 1.250". Straight shank 3/8" or 1/2" would be good.

    Thanks

    If an "Albrecht style" keyless chuck is what you're after, I have a number of extra new in box Llambrich 0-3mm (not 1/8") chucks available. Like this, except a J1 mount taper, not J0:

    Llambrich Usa JKP-30 J-0 $278.25 Keyless High Precision Drill Chuck 0.118" Cap., 0JT Mount Size, Steel | Zoro.com

    Llambrich is in the Albrecht class for accuracy and quality, made in Spain. These go for ~$275, I'd sell my extras for $115/ea including shipping. Send a pm or email through my contact if interested.

    If that doesn't work out, Misumi sells some small chucks, but they won't be as good a deal as Milland is offering.

    I would also be interested in this but a CAT40. I was drilling some 0-80 holes recently and our standard keyless chucks were not holding the shank correct because the shank is so short. Had to use our old beaten shars import mini chuck. Obviously I would like a solution that is better

    I hate to admit it, but we bought some of the cheap-ass $5 chucks on eBay and they proved to be surprisingly good. Still, you can't go wrong with the little Albrecht.

    Mhajicek, got your payment (thanks!), but didn't get a shipping address. Would you send it when you get a moment?

    Three chucks mailed, along with a tracking number sent. Should be there Monday, but give it a day or two if not due to the delivery person issues...

    Three chucks received. They look like just the ticket, thanks!

    Very good! Before you set them on their arbors, buy a Class X 3mm gauge pin, and use that to help with looking for a rotational positron on the arbor (lightly pressed on) that gives best TIR. Once you find it, do your final press to seat the chuck. Don't use a ZZ pin, those aren't necessarily straight enough.

    Nice thing about a JT1 over a JT0 is that it's much less likely to be tweaked during the full mate onto the arbor. Even so, don't go overboard with the press load.

    We used this one many moons ago. It lets you self feed.

    That's mostly what I was able to find when I was searching. I didn't want that style for use in a CNC, because the drill could resist retracting from the hole, and still be stuck in when I move in X/Y.

    Thanks
