What is a Pilot?
Pilots go through the center of the cutter. They
retract up into the mag drill arbor as the hole
is made. Pilots last a very long time and can be
used with multiple sizes of cutters.
Slot allows coolant to flow
to the cutting teeth
Other Types of Annular Cutters
Hougen makes many different annular cutters even ones for sheet metal. Below are two
styles of annular cutters for use in hand-held drills and drill presses. They offer many of
the same advantages as the mag drill annular cutters such as speed, quality of hole and
longer tool life.

A Pilot is a large nail looking object
that must be used when using
an annular cutter. It serves
three very important
functions:
1. Locates the center of
the hole
2. Allows coolant to flow down
around the slug and to the
cutting teeth
3. Ejects the slug at the end of the cut
