User Guide Recommendations for better stability: 1 Use 3xD drill instead of 5xD, if possible. 2 Mount the chamfering ring as close

as possible to the drill shank. 3 For better chamfering insert life, apply a coolant to the chamfering insert, in addition to the internal and/or external coolant. 4 A wider gap “X” between the drill and the head size is preferred (i.e. for a 14.6 mm head, use a 14 mm body rather than 14.5 mm). A slightly larger “X” dimension can dramatically increase the chamfering insert life. (1) The “L” dimension shown is relative to the common 1 mm chamfer. For other sizes, adjust “L” accordingly.
