T Style Inserts

T-style inserts, also known as triangle inserts or triangular 60° inserts, are widely used cutting tools in turning operations. Engineered with three cutting edges, T-style inserts offer versatility and efficiency in machining various materials including carbide, ceramic, and coated carbide, T-style inserts are particularly well-suited for roughing, finishing, and profiling tasks and provide excellent chip control and surface finish quality. WIDIA Victory inserts are available for light-heavy-duty applications and can be found in several sizes and grades.
