Aloris Series D80 and D80L dovetail holders accommodate all varieties of standard 80° diamond shaped carbide inserts — positive, negative or neutral rake and either left or right lead angle. Inserts are not supplied. They are designed for use with Aloris quick change tool posts and allow turning and facing operations without removing the holder from the tool post. Repeat positioning accuracy within millionths is assured when used with Aloris tool posts.
