  • countersinking tool

    i made this recently and use it all the time now. you can get the taper pretty straight by pressing a finger on the bearing and turning the plastic thumb screw. its a $5 chuck and a quick way to debur a hole.

    Cool use of a spare chuck. Assume allows you to use whatever size counter sink tool you might need eh?
    Thanks for sharing.

      I've been using a brace for deburring holes lately. I'm not 100% sure I like it better than other tools yet, but I'm still using it after several weeks.
      *** I always wanted a welding stinger that looked like the north end of a south bound chicken. Often my welds look like somebody pointed the wrong end of a chicken at the joint and squeezed until something came out. Might as well look the part.

        A $5 fancy mechanically adjustable handle for a hand counter sink. What's not to like? And a nice way to get a hand driven countersink rapidly and with little fuss.

        I didn't use an old chuck but I have made up a few hand countersinks over the years. I got carried away a bit with the aluminium one because I found three of the tips that thread into something originally. Having spares it seemed like a good idea to make up the handle shown. So far I'm still on the original tip despite frequent use on smaller holes. It's stamped 21-07-07. So almost 13 years old. The other two I made from old file handles by grinding notches into the shanks of the countersinks and epoxying into the handles. Two of them live in the drawer below the drill press and one in the tool box next to the lathe.

          I still keep a Shaviv carbide deburring tool on the lathe. Even when the blade gets dull and worn it can still make a hole burr free by rocking it from inside to out.

            I have something similar, but adapted a random wooden handle to fit the chuck thread. It's a crappy chuck that doesn't close on small drills due to one of the jaws having a couple of broken teeth, but for countersinks it works just fine.

              I'm lazy...and arthritic. I have a couple of deburing bits/countersinks with 1/4" hex shanks. They fit perfectly in my rechargeable electric screwdriver. It will change from pistol grip to straight with press of a button. I typically keep a 1/2" countersink in it all the time. It works great.

                Now THAT is one SLICK idea ! ! ! ! I might just have to keep an eye open for something along that line in the cheap tools boxes or used.

                  I've been using spare, inexpensive chucks for that and various other uses for years now. I am presently looking for a smaller one to make a dedicated deburring tool for small holes. Oh, I just remembered that I have an old battery powered drill in a box somewhere, with a small, 1/4" chuck. Perhaps I can find it.

                  I have several old Xcelite screwdriver handles with ratchets. I may fit it to one of those. Have to sacrifice a screwdriver tip to do that.

                  And if you look REAL close at an analog signal,
                  You will find that it has discrete steps.

                    the point here is that the pressing and turning motions are separate. with the regular handhelds i usually dont get a symetrical camfer except maybe on the lathe, but then you have to slow it down and your hand is close to the cutting tools. and the noga type tools dont work very well for me either, not even on straight edges, i still prefer a file.

                      It's funny but I recall when it was easy to pick up small Jacobs style chucks all over the place because they came off all the power hand drills that wore or burned out. With the full takeover of cheap keyless chucks for those and the cordless hand drills now we are all scrambling to find any of those old keyed chucks.

                        I just had a idea, some where I have on old automatic screw driver that a counter sink or a stone could be mounted to. You would just hold it on the hole and press down.

                          One is sitting on my desk as we speak . Made by Millers Falls- I can't read the rest of it. I'll have to find a shank that will fit it-

                            I started looking for a small drill chuck. Then I remembered that they make countersinks with 1/4" hex shanks to fit the screwdriver handles. And wonder of wonders, I have a set of them, sitting on my drill press. All I really need to do is bring a screwdriver handle there when I am drilling and I can deburr any size hole I am likely to drill.

                            Boy, that was an inexpensive solution.

                            Perhaps I will buy a new ratchet style handle just for the drill press. But then, there is the milling machine. I guess I need a set there too.

                              I took a picture of mine yesterday. I had forgotten it was a Ryobi. It's a few years old but still works great. I think it was one of the first Lithium rechargeable tools I ever bought.
