insert is seen in the side view of the vertical tool holder (i.e., looking down the axis
of the part being machined) and in the top view of the profiling tool holder.

1. A small-shank tool for an automatic lathe, comprising:
a tool shank defining a rectangular cross-sectional shape and having a

defined at one end of the shank by two tool-supporting surfaces oriented at
an acute angle relative to each other for receiving and supporting a tool
insert, wherein one of the tool-supporting surfaces is oriented approximately
parallel to an adjacent side of the shank forming an elongated body portion
between the tool recess and the respective side of the shank and having a
thickness of at least approximately 1.0 mm;
an approximately rhomboidal-shape tool insert defined by an
inscribed circle having a diameter less than approximately 90% of the shank
width, and defining a fastener aperture extending through the approximate
center of the inscribed circle having a diameter less than approximately 70%
of the diameter of the inscribed circle, the rhomboidal-shaped tool insert
being received within the tool recess with two sides of the insert each fully
engaging a respective tool-supporting surface of the shank without any
substantial portion of the two sides extending beyond the respective
tool-supporting surfaces, and with a substantial portion of the other two
