Description
The OSG Carbide 3 Flute End Mill Square is a versatile cutting tool built for general machining tasks. With a 2.5 mm diameter, a regular-length body, and center-cutting geometry, it handles milling, slotting, and profiling across a wide range of materials. The TiAlN coating boosts wear resistance and tool life, helping you complete jobs with fewer tool changes and more consistent results.
- Three-flute design for efficient cutting: The 3-flute geometry delivers steady chip evacuation and strong material removal, enabling faster cycles and smoother finishes on a variety of materials.
- TiAlN coating for extended tool life: Hard TiAlN coating provides superior wear resistance and allows higher cutting speeds, reducing downtime and increasing productivity in demanding machining tasks.
- Regular-length center-cutting design: This rigid, general-purpose end mill delivers reliable plunging and full-width slotting, making it ideal for everyday milling without swapping tools.
Whether you're building prototypes, repairing equipment, or performing routine maintenance, this end mill delivers dependable performance across materials. The combination of carbide strength, TiAlN coating, and a proven 3-flute geometry translates to consistent dimensions, clean finishes, and reduced tool changes, helping you keep projects on schedule and within tolerance.
