T-A® Style Head • Utilizes both T-A Pro and T-A inserts (0 - 2 series). • Multiple geometry options are available to achieve optimal results in different types of applications.

GEN3SYS® Style Head • Utilizes both GEN3SYS XT and XT Pro inserts (15 - 32 series). • ISO geometry options are available to achieve optimal results in different types of applications.

Insert Application Recommendations Carbide Grade Options P35 (C5)

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

K35 (C1)

IC Insert AM300® • The design allows for excellent chip control and aggressive penetration rates. • The proprietary AM300 coatings increase tool life above competitors’ premium coatings.

K25 (C2)

Additional Geometry Option High Rake (HR)

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