The references demonstrate that one of ordinary skill in the art of designing
machine tools had knowledge of: (1) mounting profiling and vertical inserts in a
recess in the tool shank with two sides of the insert supported by tool-supporting
surfaces of the recess (Max Bar, ETCO, Nikcole, Kyocera); (2) shank widths less
than 9 mm and, in particular, 7 mm and 8 mm widths ('400 patent, col. 3,
lines 40-44; Kyocera and Nikcole disclose an 8 mm width shank for a profiling
tool and a vertical tool, respectively); (3) 8 mm shank widths with inserts having a
7 mm inscribed circle (IC) diameter (Nikcole) or a 0.250" IC diameter (Kyocera);
(4) inserts having an IC diameter less than 90% of the shank width (Max Bar,
ETCO, Nikcole, Kyocera) and a fastener aperture less than 70% of the IC diameter
(Max Bar, Nikcole, Kyocera); (5) mounting inserts using countersunk head screws
(Max Bar, ETCO, Nikcole, Kyocera); (6) a lip thickness of at least 1 mm
(Max Bar, ETCO, Nikcole, Kyocera); and (7) using inserts with a smaller
