THREAD TURNING TIP Double-Ended Peripheral Ground Insert with a Flat Top Rake
(without Chipformer)
Designed for threading on short chipping materials such as brass and cast iron. The use
of the flat top rake inserts on these materials results in improved surface quality and less
chatter, compared to inserts with a chipformer. As a result, cutting speeds can be increased.
The following picture shows the excellent surface quality obtained by using a TIP.... A-Type
insert on a brass workpiece. These types of inserts are available for partial profile.
