Description

The OSG Carbide 4 Flute End Mill with a corner radius, long-length design, and TiSlN coating is a specialized tool engineered for precision machining in exotic materials. Its 10 mm diameter and 1.5 mm corner radius provide accurate profiles on demanding workpieces, while the extended length offers essential reach for deep pockets, slots, and hard‑to‑access features. This end mill is ideal for engineers, machinists, and hobbyists who need reliable performance in challenging applications.

Built for durability and consistent results, the TiSlN coating enhances wear resistance and heat tolerance, helping the tool maintain sharpness over extended runtime. Whether you're tackling aerospace alloys, specialized steels, or other exotic materials, this end mill delivers stable cutting, precise corners, and dependable longevity.

  • Long-length reach for deep features: Extends into deep pockets and complex geometries while maintaining cutting stability, reducing tool changes and keeping workflows efficient.
  • TiSlN coating for durability: Hard, wear‑resistant surface that stands up to high temperatures and abrasive exotic materials, delivering longer tool life and fewer replacements.
  • 4‑flute design with corner radius for precision finish: Optimized chip evacuation and clean corners ensure consistent radii and smooth surface finishes on challenging workpieces.

This end mill helps you complete complex projects with tighter tolerances, faster cycle times, and fewer interruptions. The extended reach combined with a durable coating and precise geometry enables reliable performance across demanding exotic-material applications, empowering you to achieve high-quality results with confidence.
