Title: Arrangement for keeping tools of the drilling, milling, boring type etc. in readiness for use on machine tools

Abstract: A tool holder for the shank tools of a drilling, boring or milling machine comprises a table having a pair of vertically spaced coaxial horizontal disks including a smaller diameter upper disk and a larger diameter lower disk and spacer holding the disks apart and connecting them together. The table is mounted upon a flanged shaft which is rotatable in a bearing sleeve containing friction means limiting the rotation of the table. The upper disk is formed with rectangular arrays of tapered or nontapered holes adapted to receive tool shanks while the lower disk is provided outside the outline of the upper disk with circular arrays of holes with the holes of each array lying between the holes of an adjacent array.
