Split Points - DRILL DOCTOR XP Mode D'emploi

Split Points

Split point drill bits prevent walk-around on the material before
they begin to cut. This feature is described as self-centering. The
need to center punch is effectively eliminated. A standard drill
bit chisel point has to wear an area in the middle of the hole to
be drilled before the cutting edges will remove material. Due to
its additional cutting lips along the chisel edge, a split point will
begin cutting immediately. Up to 70% less thrust (when compared
to a non-split or conventional point) is required to drill a hole with
a split point.
