respective end of the tool shank," as recited in claim 10. We found that these
limitations are not taught by the small amount that the tip extends beyond the
shank due to the 7° relief angle in Kyocera. Kennametal is applied to show a tool
shank "wherein the first and second tool-supporting surfaces are oriented at an
angle of approximately 35° relative to each other," as recited in claims 1 and 11.
See EA17. Kennametal is a profiling tool like Kyocera where the tip of the insert
extend beyond the shank due to a 5° relief angle, which is even less than the 7°
angle in Kyocera. Therefore, Kennametal does not cure the deficiencies of
Kyocera. Accordingly, the rejection of claims 2 and 11 is reversed.
Claims 17 and 18
The examiner concludes that it would have been obvious to modify the 55°
angle in Kyocera to be 35° given the 35° teachings of Kennametal "in order to
facilitate easier accessing and deeper tool feeding into the workpiece having a
narrow space for the KYOCERA's tool during a cutting process" (FR18). The
examiner's rejection is also based on the finding that a substantial portion of the
sides of the insert in Kyocera extend beyond the end of the tool shank.
