Description

The OSG Carbide High Helix End Mill (8 mm diameter, corner radius R) Square Edge is a versatile cutting tool designed for general machining. Its regular-length body and square-edge geometry deliver reliable results across milling, slotting, and profiling tasks.

Coated with TiAlN for wear resistance and featuring a high-helix design, it promotes efficient chip evacuation and reduces cutting forces. This combination makes it suitable for demanding operations in aerospace, automotive, and general manufacturing, delivering consistent, high-quality finishes.

  • High-helix geometry for efficient chip evacuation: The aggressive helix pulls chips away from the cutting zone quickly, reducing heat and improving control for smoother cuts and longer tool life.
  • TiAlN coating for extended wear resistance: The coating protects the cutting edge from heat and wear, enabling higher speeds and longer intervals between tool changes in demanding materials.
  • Regular-length body with corner-radius versatility: The balanced length provides rigidity and control for general milling, while the corner radius enables smooth corners and clean profiles in slots and contours.

This end mill is designed to deliver fast material removal, durable edge life, and reliable results across a wide range of materials and applications. The combination of carbide rigidity, TiAlN protection, and thoughtful geometry helps reduce downtime, maintain tight tolerances, and support consistent performance from part to part.
