With Tiger-tec® Silver, Walter offers a coating technology for indexable inserts that is unique worldwide, recognizable by the designation key "-S" at the end of the grade description - The special aluminium oxide layer with optimized microstructure reduces wear during turning, milling and drilling operations and increases toughness and temperature resistance at the same time. This enables users to achieve significantly higher cutting data.
