  • Patent number: 3957307
    Abstract: A rough cutter rotary mining tool formed of a support lug having an elongated, open ended, cylindrical bore and a cutter bit having a cylindrical shank portion extending through and loosely fitted within the bore, with the cutter head portion extending a distance beyond the forward end of the bore. An integral shoulder portion is arranged between the head and shank portions for engaging the lug at the forward end of the bore and a removable retaining clip is mounted upon the free end of the shank portion for engaging the rear end of the lug at the bore. The shank portion is loosely movable endwise a short distance relative to the bore. Also, the diameter of the shank portion is considerably smaller than the bore portion to form a space therebetween and so that the shank may easily rotate within and move transversely of the bore. Thus, small sand-like particles may pass through the bore around the shank during use of the tool.
