b. Tools or cutters;
c. Extruder worms;
d. Engraved or faceted jewelry parts; or
e. Dental prostheses.
Note 3:
A machine tool having at least two of the three turning, milling or grinding capabilities (e.g., a turning machine with milling capability), must be evaluated against each applicable entry 2B001.a, .b or .c.
Note 4:
A machine tool having an additive manufacturing capability in addition to a turning, milling or grinding capability must be evaluated against each applicable entry 2B001.a, .b or .c.
