User Guide Recommendation for better stability: Use 3xD drill instead of 5xD if possible. Mount the ring as close as possible to the drill shank. In order to get better chamfer insert life it is suggested to apply coolant to the chamfer insert in addition to the through the drill coolant and or external coolant.. A wider difference "X" between the drill body and the replaceable point size is preferred (i.e. for .575" replaceable point select .551" drill body rather than .571"). 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
