Description

The OSG Carbide 4 Flute End Mill with a corner radius and TiSlN coating is a precision cutting tool designed for machining exotic materials. With four flutes and a built-in corner radius, it delivers steady, efficient material removal and tighter control on part geometry. Its TiSlN coating enhances wear resistance, helping the tool stay sharp longer in demanding operations.

This end mill is ideal for machinists, engineers, and shops that require dependable performance in tough materials—from high-temperature alloys to advanced composites—while delivering consistent results in profiling, pocketing, and contouring tasks.

  • Corner Radius for Strong Edges and Finished Corners: The R2 corner radius adds edge strength where it matters most and helps produce cleaner, more accurate corners during profiling and pocketing, reducing rework and improving part accuracy.
  • TiSlN Coating for Durability: The TiSlN coating boosts hardness and wear resistance, extending tool life in high-heat, abrasive environments typical of exotic materials and helping maintain sharpness through more cuts between regrinds.
  • 10 mm Diameter with 4-Flute Design: A stable, efficient cutting geometry that delivers steady chip evacuation and consistent material removal, enabling smoother surfaces and reliable results across challenging materials.

By combining a robust corner radius, four-flute efficiency, and a durable TiSlN coating, this end mill supports faster, more predictable machining with fewer tool changes. It helps you achieve precise pockets and profiles, reduces downtime, and delivers reliable performance when working with exotic materials—so you can finish jobs faster with confidence.
