Description
The OSG Carbide 3 Flute End Mill with a corner radius and Diamond-Like Carbon (DLC) coating is a precision cutting tool designed for aluminum work. Its three-flute geometry and built-in corner radius deliver stable, controlled material removal for crisp edges and reliable finishes, even on demanding aluminum projects.
- Three-flute design for efficient aluminum removal: Optimized for aluminum, this geometry provides strong rigidity and effective chip evacuation, helping you work faster with consistent surface quality.
- DLC coating for extended tool life: The Diamond-Like Carbon coating reduces wear and maintains edge sharpness, increasing tool life and reducing downtime in repetitive aluminum milling.
- Corner radius for precise profiles: The R3 corner radius enables accurate inside corners and smoother edge finishes, improving part geometry and reducing the need for additional finishing passes.
In aluminum machining, this end mill helps you achieve precise dimensions and high-quality finishes with reliable, long-lasting performance. The DLC-coated carbide construction is designed to deliver consistent results across production runs, giving you confidence to tackle demanding aluminum applications with fewer tool changes and rework.
