Hunger Expanding Pilots With Collet
Expanding pilots are available to fit valve guides from 5,9 to 12,9 mm in diameter.
Two or more collets are available for each pilot size. Collets of different length L are available for most pilot sizes 7/1 - 12/1 to achieve perfect centering in case of very short valve guides.
When selecting a pilot make sure that the length L of the collet is shorter than the length of the valve guide.
