Description

The OSG Carbide 4 Flute End Mill with a corner radius and TiSlN coating is a purpose-built cutting tool designed for machining exotic materials. This 4 mm diameter end mill features a precise 0.3 mm corner radius (R0.3), delivering fast material removal while maintaining stability and dimensional accuracy across challenging jobs.

Built for machinists who work with tough, non-standard materials, the TiSlN coating enhances durability and wear resistance. This combination of coating and geometry helps you push demanding operations with confidence, delivering dependable performance from roughing to finishing.

  • Four-flute design for efficient material removal: Provides increased rigidity and better chip evacuation, enabling faster cuts and smoother finishes even in exotic materials.
  • Corner radius of 0.3 mm (R0.3): Strengthens edges to reduce chipping and improve contour accuracy on complex profiles, extending tool life and part accuracy.
  • TiSlN coating for durability: Enhances wear resistance and lowers friction, delivering longer tool life and more reliable performance in demanding materials.

This end mill combines a robust carbide body, a precise corner radius, and TiSlN coating to support consistent, high-quality results. Its stability and efficiency help streamline your workflow, reduce tool changes, and improve overall productivity on projects that demand both precision and longevity.
