  • Drilling A Square Hole, MUST SEE

    I have to say that this is a first for me other than using a mortising chisel.
    However ............ not going to work with a hand drill or light duty drill press.

      Joe your link isn't working for me.
      Is this perhaps what you are linking to?

        It`s a Watts drill. The original patent was applied for back in November 1916 and the patent, #1241176, was granted September 25, 1917 to Harry J. Watts of Turtle Creek, Pennsylvania.

            I'll be........... I guess they never gained popularity, I've never seen them in any tool catalogs.

                It figures that it was invented here and reinvented years later across the pond.

                  Has anyone here used one? I have a question. How do you "index"
                  the square?

                      Thats a good point. You would have to locate an edge of the cutter in relation to where you want your corners to be or no telling where your corners will end up.

                          That's Dijet -- a Japanese company. Their headquarters is in Osaka.

                            Square Hole

                            I called them and tried to buy one. The person at Dijet told me they are only sold in Japan, not available here.

                              Look at this video to see how it is done. The cam rides in a form that establishes the path of the cutting edges.

                              At the end of the project, there is a profound difference between spare parts and extra parts.
