Roughing: Use the largest available corner radius unless otherwise specified.

Finish boring: Use the smallest available corner radius to minimize tool deflection.

Best finish: Generally start with your feed at 25% of insert nose radius. Optimal speeds and feeds depend upon material, tool overhang, and setup conditions.
