  • Bought a Used Albrecht Chuck

    Bought a 1/8-5/8 Albrecht chuck for 50 bucks. Seem to work very smoothly. What can go wrong with it and how do I check it for accuracy?

    Just use it and marvel at how well it works.
    I seldom do anything within the scope of logical reason and calculated cost/benefit, etc- I'm following my passion-

      If you're interested in cleaning your chuck, here is the proceedure. It also gives you the opportunity to check the condition of the jaws.

        Try checking with a range of drill sizes and a dti. Hopefully the runout will be 0.003" tir or better.
        I have often wondered what the purpose of the collar is on these and some other makes of keyless.

          The purpose of the collar? Wouldn't that be to hold it still while tightening and opening it? Keyless chucks are a two hand operation. That's one of the reasons why I don't use them. One hand to hold the drill, one to hold the collar, and one to tighten it. OK on a hand drill, but in a drill press or mill.....

            To tighten it up, yes, it takes two hands. To mount a bit into one, one hand to hold the bit, one hand to snug up the chuck. Once snug, the bit will remain where it is, so two hands to tighten it up is what it takes. A good keyless chuck will spin down to the drill bit just as easily as a keyed chuck.

              One for the drill, one for the collar, and one to tighten? That's three hands!

              If it takes you three hands for a keyless chuck, I'd like to know how you manage with one hand for a keyed chuck.It can be done,of course, but if you have a second hand you might as well use it. It is easier and faster.

                left hand on the chuck, index and middle fingers wrapped around the hood, ring and pinky around the drill, start/stop the spindle - but I have hands like leather. Old boot leather.

                  Yes, of course, but if you're using a keyed chuck, you have the key in your other hand ready to use, don't you?

                  And if someone with more delicate hands doesn't care to start the spindle, he still has the thumb and forefinger of the hand holding the drill to snug up the chuck. Either way, it seems more natural and slightly quicker to use the other hand for the key, if the hand is not needed to hold the work on the table.

                  So, normally a two-handed operation, with keyed or keyless chuck.

                    They don't all have the collar, even in Morse taper: https://www.cutwel.co.uk/tool-holdin...al-drill-chuck
                    I have an Albrecht 0-10mm and a Porta 2-16mm with the collar also.

                      Another tip I read.

                      Do not put the drill bit all the way up into the Chuck.

                        Interesting. I usually butt the drill all the way in so I don’t lose my Z offset when drilling on the CNCs.

                          Most people use ER collet holders for holding drill bits in CNC machines.
                          They have a backstop to hold the Z in place.
                          An Albrecht chuck is totally variable where the tool is in the Z.

                            As a side note to this thread...
                            I have bought a few (3) of the Shars brand keyless chucks.
                            Their premium line that is about $55 to $85 depending on
                            if you get it with the shank or not. Anyhow, I am super pleased
                            with them. I have one with the separate shank on my Jig Borer
                            and I get half a thou of runout. I a super pleased with that.
                            So go ahead and flame Doozer for buying import tooling.
                            I am very selective about what I buy on the cheap.
                            But I was not going to pay $300+ for a German Albrecht chuck.
                            I just thought I would pass on my good experience with Shars
                            keyless chucks.

                              My Cutwell 1/2", 13mm with integral R8 shank looks exactly like the Shars chucks, probably made in the same factory. Mine has 0.0015" tir which is good enough for me.
