Description
The OSG Carbide 4 Flute End Mill with Corner Radius is a versatile cutting tool designed for general machining tasks. With a 5 mm diameter and a corner radius (R2), this regular-length, center-cutting end mill is ideal for milling, slotting, and profiling across a wide range of materials and applications.
Coated with TiAlN, it offers enhanced wear resistance and longevity, helping you achieve consistent results even in demanding operations. The four-flute geometry delivers efficient material removal, while the corner radius promotes smoother cuts, reduced chatter, and superior surface finish.
- TiAlN coating for enhanced durability: The TiAlN coating extends tool life and resists wear in high-heat cutting, helping maintain precision and repeatability through long production runs.
- Corner radius for smoother finishes: The R2 corner radius reduces edge chipping and produces cleaner, flatter surfaces with better overall surface quality.
- Center-cutting, four-flute design for versatile cutting: Center-cutting enables plunging and profiling with stable, efficient material removal across a range of general milling tasks.
With this end mill, you’ll experience dependable performance from setup to finish. Its TiAlN coating guards against wear, while the corner radius and four-flute geometry deliver smooth finishes and efficient material removal. This combination supports faster cycles, fewer passes, and consistent results, helping you complete projects with confidence and improve overall productivity.
