  • Broken drill save.

    A #6 drill snapped off yesterday as it broke through the 3/4" steel table top & caught the edge of the cross-brace underneath it. Knew it should have had a stop collar on it!

    Anyway the method used to extract the piece actually worked so it's worth a picture & a post. Who knows, it might work for someone else down the road.

    It was broken off flush with the surface. 2 pieces of 1/16" music wire were tapped down as far as they would go into the gullets between the flutes. The wire ends were clamped in a large Vise-Grip & a firm CCW twist applied. The table was whacked right next to it with a brass hammer & voila! The drill instantly turned & almost jumped out of the hole. Who'd a thunk a crazy idea actually works as planned sometimes!

        Shoot, you never know when a broken drill might come in handy. I'm so tight I take my glasses off when I'm not looking at anything!

              I must be mean, I'd resharpen any broken drill, sometimes the web needs thinning on thick drills, but they do work as spotting drills, I'm getting better at free handing again, lost it when I had access to the old brierly drill sharpener in work, brilliant machine but you get to rely on the thing and loose the ability to sharpen drills, one of the most used things I ever learned in school, the teacher gave us all a 3/8 drill, we had to regrind it every week till we ran out of drill, then you got another one!
              Why don't they teach metalwork anymore?, it's crazy, or woodwork.
              It was my favourite lesson.

                I read it that the "save" was the drill got pulled out of where there should be a hole, not that the drill was inherently valuable......

                The emoticons suggest that is where most of the odd replies are with it, but you never know.......

                    Yup, Mr. Hindsight is yelling in my ear: "Why didn't you name this thread 'Broken drill removal'."

                      What you are describing is the same as a broken tap extractor . The wires for 2 or 3 flutes are built into a handle and extend into the flutes as far as possible and unscrew the broken stub. You did it freestyle with 2 wires and a vise grip.

                        Don't forget the hammer. Everything works better with a hammer.

                          I'm wondering... Why not slide a sleeve over the broken part of the bit and solder/weld the bit back together? It needed a stop collar anyway, right? (-:

                          Hey DICKEYBIRD, good tip! I'll add it to the list for when this inevitably happens to me.

                            Just out of curiosity, was the broken drill Asian or Made in USA?

                              Naw, there is a HUGE difference between them.......

                              The difference is that THIS approach WORKED. I do not recall EVER having a tap extractor work. But I have the busted remains of several extractors to show for trying.
