T-A® Style Head • UƟlizes both T-A Pro and T-A inserts (0 - 2 series). • MulƟple geometry opƟons are available to achieve opƟmal results in different types of applicaƟons.

GEN3SYS® Style Head • UƟlizes both GEN3SYS XT and XT Pro inserts (15 - 32 series). • ISO geometry opƟons are available to achieve opƟmal results in different types of applicaƟons.

Insert ApplicaƟon RecommendaƟons Carbide Grade OpƟons P35 (C5)

General purpose carbide grade suitable for most applicaƟons. Common application in steels and stainless steels. Toughest carbide grade. Provides the best combinaƟon of edge strength and tool life. Recommended for less rigid applications. Higher wear-resistant carbide suitable for abrasive material applicaƟons. Recommended for grey, ductile, and nodular irons.

K35 (C1)

IC Insert AM300® • The design allows for excellent chip control and aggressive penetraƟon rates. • The proprietary AM300 coaƟngs increase tool life above compeƟtors’ premium coaƟngs.

K25 (C2)

AddiƟonal Geometry OpƟon High Rake (HR)

Provides superior chip control and tool life in long-chipping carbon and alloy steels below 200 BHN.
