These are simple tools suitable for all types of lathe machines, available with and without
coolant channels. There are 2 types of boring bars for GEPI inserts and 2 types of boring
bars for TIPI inserts. The bars (in the CUT-GRIP family) can be produced from steel or solid
carbide. The solid carbide boring bars expand the current boring overhang range and provide
improved performance due to their high rigidity feature.
