S791 BARREL END MILL SOLID MILLING CUTTERS

INTRODUCTION We have launched an advanced barrel-shaped end mill for efficient five- axis machining in die and mold and aerospace applications. The new S791 cutter provides excellent surface quality and is suitable for semi-finishing

and finishing in steels, stainless steels, cast iron and super-alloys. Its design includes a nose radius for fillet milling and a tangential form radius for curved and deep wall surface machining.

FEATURES & BENEFITS

This enables:

• A greater area of contact with the workpiece, increasing tool life and reducing cycle time. a

• Fewer passes, leading to more than 50% time savings.
• Better surface quality and characteristics, minimizing the time spent polishing. An AlCrN coating for thermal stability, reduced
• All the benefits usually associated with a robust ball friction, excellent wear resistance and prolonged nose end mill. durability.
• Positive rake angle for smooth cutting action in stainless steels and super-alloys, reducing the risk of work-hardening .
