User Guide
Recommendations for better stability:
1. Use 3xD drill instead of 5xD, if possible.
2. Mount the chamfer ring as close as possible 1mm (1)
to the drill shank.
3. For better chamfering insert life, apply a L
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 head 14.6 mm,
use body of 14 mm rather than of 14.5 mm).
A slightly larger “X” dimension can dramatically
increase the chamfering insert life.
(1) The “L” dimension shown is relative to the X
common 1 mm chamfer. (maximize)
5 For other sizes, adjust “L” accordingly.
