Expanding pilots are a great alternative when you need a pilot size that's just a little larger or a little smaller than you can find in a static size. These pilots have a .385" top so will work in most applications that use that size. Do not use expanding pilots with a Valve Seat Cutting system such as the 3-D Fast Cut or other multi-angle cutting system.Â
Expanding pilots come complete with an expander and a collet. Replacements are available separately.
