To fulfill the need for a smaller bushing extractor than the Series 86, Crozier developed the
Series 100 for the automotive, aircraft engine and component, and electronic instrument fields.
Shown to the right is a cut-away view of the Series 100 extraction of a part from a blind hole.
The series is offered in a variety of sets, or may be purchased individually. The smallest
bushing, which the series will extract, is ¼ inch diameter. The maximum size is ¾ inch diameter.
This offers an overlap with the larger series 86.
