.375" Top Expanding Pilots

Expanding pilots are a great alternative when you can't find a tapered pilot that fits an odd-sized guide. These pilots are designed to fit a range from approximately .003" smaller to .017" larger than the listed size. They can be used with Neway Valve Seat Cutters and valve seat grinding, but we don't recommend using they for Valve Seat Cutting with the 3-D Fast Cut or other multi-angle cutting systems.

Expanding pilots come complete with an expander and collet. Replacements are available separately.
