The Tiger-Tec Silver WPP05S insert grade is a wear-resistant, indexable TNGG Insert grade from Walter USA said to deliver high performance and productivity in steel machining, particularly for roughing forged components Cemented Carbide Inserts and long production runs. The insert’s thicker Tiger-Tec Silver coating offers optimized aluminum oxide microstructure, while its post-coating treatment provides greater reliability, increased toughness and reduced downtime due to chipping, especially in high-volume production. The inserts are capable of operating reliably at high cutting speeds with greater metal removal rates, and are said to provide increased tool life at high speeds.

The insert grade is designed with a new substrate said to better resist plastic deformation. According to the company, this is particularly important at higher cutting speeds required for increased productivity. In addition, a thicker cobalt-enriched zone yields greater toughness and process reliability. The inserts are available in MP3, MP5, RP5 and NRF geometries.
