A slightly larger “X” dimension can dramatically increase the chamfer insert life. Trouble Shooting • Bad chamfer surface finish (vibrations) Solutions: • Use a shorter drill. • Move the ring closer to the drill shank. • Reduce the cutting speed while cutting th chamfer. • Chips packed on the ring flutes: • Ensure that the ring is positioned as shown in the mounting instructions. • Adjust the cutting speed. • Use a pecking cycle. 683
