purchasing router bits, you have the option of selecting either
piloted or un-piloted bits.
Router Bits are used when cutting a decorative profile
on the edge of a straight or curved workpiece where the entire
edge of the stock is not to be removed.
selecting piloted bits, you have a choice of bits with a solid
pilot...or a bearing pilot. Although solid pilot bits are
less costly, they can easily create friction which results
in unsightly burn marks when making the cut.
pilot bits are more expensive, but provide the advantage of
smoother running operation and no burning of the workpiece
Router Bits offer no edge guides and have flutes that
will cut all the way to their tips. They are therefore designed
for use on projects where the entire edge of the workpiece
is to be removed - or a decorative cut is to be made somewhere
within the perimeter of the stock (usually on its surface).
a result, un-piloted bits are most commonly guided during
use by a fixture, guide pin or a fence...although many practiced
craftsmen create incredible designs free-hand.
