• Fillet.  (1) A narrow bar as a design element; also an ornamental headband or small crown (diadem). The fillet as a headband is often lettered in coin and medal design.
  Fillet.  (2) A narrow strip of metal to be rolled into proper thickness for blanking into planchets; a small ingot. When metal is melted and formulated for coinage alloy, the melt typically contains several thousand ounces. Small amounts are taken out of the crucible with a dipping cup and poured into book molds. When cooled these ingots are broken open and the fillet is removed. The fillet ends are trimmed to remove uneven material (see topping machine) and the surfaces are filled smooth on all sides (DEBURRED) and swaged or flattened (tapered) on one end. This tapered end is fed into a break-down ROLLING MILL.
