Eight Faceted
Composite Drill
The point geometries of this
double fluted drill make it ideal for
composites. That’s why it’s become
standard equipment for certain
aerospace applications. The point
concept is similar to the long taper on
the AM12FH drill.
The side angles serve to clean up any
fraying or delamination after the point
exits the material. Like all of our high
performance tools, we can customize
this drill for your application.

With its diamond coating for long life,
118
º point, 8.5º reaming taper, and
5
º flute helix, this is one of AMAMCO
Tool’s primary composite drills. The
geometries make for easy penetration
without breakout or delamination.
In the aerospace industry,
it’s known variously as a “pencil drill,”
“
composite drill,” or “drill reamer.”
The design ensures a clean hole
because any potential delamination
created by the point upon exit, is
immediately cleaned up by the taper.
The four flutes ream the hole to an
extremely tight tolerance.
