bottom of the tool insert, so it is a "profiling" tool. The tool holder accepts an
insert with a 0.250" IC, so the elongated body portion (corresponding to lip 24 in
Fig. 2 of the '400 patent) is 8 mm - 6.35 mm = 1.65 mm, and, so, has a "thickness
of at least approximately 1.0 mm," as recited in claims 1, 10, and 16. A
representative insert is DCMH-21.50HQ, which has a rhombus shape with an IC
diameter of 0.250" (= 6.35 mm), which is "less than approximately 90% of the
shank width" (0.9 x 8 mm = 7.2 mm), as recited in claims 1 and 16, and falls
"within the range of approximately 5.5 mm through 6.5 mm," as recited in
claims 4, 10, and 19. The insert has an acute angle of 55° between sides at the
cutting tips and a hole diameter of 0.110" (= 2.794 mm) (page 11 (number not
shown); also Bates numbered "E618") to accept the 2.5 mm diameter SB-2570
screw. SB-2570 is a countersunk screw having a 60° countersink angle having a
head diameter of 0.138" (= 3.505 mm) (Exhibit 7). Thus, the head diameter is
"less than approximately 70% of the diameter of the inscribed circle"
(0.7 x 6.35 mm = 4.45 mm) as recited in claim 1 and is "within the range of
approximately 3 mm through 4.5 mm," as recited in claims 5 and 10; and has a
countersink angle within the range of claim 6, and is specifically 60° as recited in
