3PKT100408 / 3PKT100404 Milling Inserts

The 3PKT100408 3PKT100404 Milling Inserts are high-performance carbide inserts designed for indexable milling cutters. Manufactured from premium carbide with advanced PVD coating, the 3PKT100408 3PKT100404 Milling Inserts deliver excellent wear resistance, toughness, and long tool life. Featuring a triangular geometry with three cutting edges, the 3PKT100408 3PKT100404 Milling Inserts ensure efficient chip evacuation, reduced cutting forces, and stable performance in steels, stainless steels, and cast irons.

These inserts are commonly used in face milling, shoulder milling, and slotting applications. Thanks to their sharp edges and optimized chipbreaker design, they provide superior surface quality in both roughing and semi-finishing operations. The 3PKT100404 version has a smaller 0.4 mm corner radius, suitable for fine finishing, while the 3PKT100408 version with a 0.8 mm corner radius offers stronger edges for heavier cuts.

The 3PKT series is widely used in automotive, mold-making, and precision engineering industries where productivity, stability, and cost efficiency are essential.
