One difference between the subject matter of independent claim 10 and
Nikcole is that Nikcole does not disclose the limitations indicated by underlining in
"two sides of the insert each fully engaging a respective tool-supporting surface of

disclose a "head having a maximum diameter within the range of approximately

One difference between the subject matter of independent claim 11 and
